Largely ignored in transpersonal studies to date, dark magic involves socially-transgressive processes called becoming-intense and becoming-animal that produce non-ordinary
states useful in the arts, hunting, sex, and fighting. War magic, a form of dark magic that involves powers of destruction and invulnerability, is ubiquitous and universal, and
one of its primary features is the production of helpful, nonordinary states in combat. Berserkergang (going berserk) is one such state, the latest documented in a long history
of Indo-European ecstatic warrior cults. Berserkergang was the battle-trance of the elite consecrated warrior-shamans of Odin, god of magic, poetry, battle, and death. Distinguishing features of berserkergang include invulnerability to fire and bladed
weapons, shapeshifting, superhuman strength, laughing at death, and transpersonal identification with comrades and Odin. Cross-cultural interpretations have tended to
denigrate berserkergang, including modern arguments that attribute it to intoxication, genetic flaws, or pathology. Not only are such arguments inadequate to account for the data, but also the features of berserkergang are considered signs of spiritual attainment in various traditions up to the present day, and the techniques for achieving berserkergang remain in use in many spiritual traditions as well as on the battlefield.

anally rape them with the tail of an iguana or armadillo
until the intestinal wall is shredded and the rectum
sufficiently ripped to be stuffed with bags of astringent
herbs, bringing on a slow, agonizing death (Whitehead,
2002). The shamans later violate their victims’ corpses to
eat some of the liquifying remains for magical purposes.
Motives for such assaults are typically power, status,
jealousy, or revenge.
Not all war sorcery is as revolting as that of the
kanaimà shamans. In fact, a quintessentially Western form
of war magic, berserkergang (going berserk, the common
English rendering of Old Norse berserksgangr), a virtually
unknown bit of the spiritual heritage of people of European
descent, features practices and qualities utilized by different
religious traditions as signs of spiritual attainment. The
battle trance represented by berserkergang, which died out
during the Viking Age, was the last version of an Indo-
European ecstatic warrior cult dating back to the Bronze
Age (Speidel, 2002, 2004), yet the practices for cultivating
it remain in use by different religious traditions and on
the battlefield today. Berserkergang was a nonordinary,
transpersonal state that provided a combat advantage in
addition to its spiritual attributes.
The Origins of War Magic
People have always needed the power to survive
physical threat, so it is natural that magical practices,
inherently about acquiring power, would have coalesced to
cope with danger (limited to warfare for this discussion).
Humans share a repertory of aggressive displays with other
vertebrates for con-specific conflict designed to frighten the
opponent to the point of preferring to avoid confrontation
(e.g., MacLean, 1973, 1990). For Homo sapiens, however,
conflict frequently exceeds dominance displays to involve
mass killing of fellow humans. But even in bellicose
cultures it is not easy for humans to kill their own kind in
close combat, the predominant form of warfare for most
of human history, which employs bladed and blunt-force
weapons in addition to short-range projectiles, such as
slings, arrows, and throwing spears. The closer combatants
are physically, the greater their need to dissociate from their
humanity (Grossman, 1996). The opponent must be made
into “other” in the attacker’s mind, while the attacker must
also become “other” so that the prohibitions against killing
do not apply (Grossman, 1996; Roscoe, 2007).
Whereas religious forms of spirituality tend to
promote socialization and morality for civilized living, a
process called becoming-human (Deleuze & Guattari, 2004),
war spirituality promotes dehumanizing processes that put
people into a liminal, socially-transgressive state, referred to
as becoming-intense and becoming-animal. By dissociating
from his humanity and, therefore, society’s norms, the
combatant has no conscience and no guilt over killing. (War
is by no means the only venue for becoming-intense and
becoming-animal; these processes are invoked in numerous
activities, including hunting, theater, dance, sex, shamanic
trance, sports, and martial arts; Farrer, 2009, 2014).
Over time instinctive defensive and aggressive
behaviors became patterned activities to enhance becoming-
intense and becoming-animal when people fought, that
occur universally (Carlson, 2006; W. Miller, 1990; D.
Miller, 2000; Lincoln, 1991; Roscoe, 2007). Loud noises
and vigorous, threatening movements evolved into ritual
behaviors for combat (Ehrenreich, 1997; Gibson, 2011;
Jordania, 2011; Kogan, 1997; Nettle, 1961; Roscoe, 2007):
1) taunting and other forms of verbal aggression raise
the combatants’ anger before they physically engage; 2)
rhythmically-organized vocalizations, such as singing and
the battle cry, often amplified by horns and drums, invoke
the gods, inflame mood, unify the group, communicate
determination, and intimidate the opponent; and 3)
repetitive, rhythmic group movements, such as war-
dancing and marching, promote solidarity. War-dances
performed in advance of battle invoke the gods and ésprit
de corps, and when performed in front of the enemy blunt
the opponent’s will to fight. A familiar warrior magic
display that combines taunting, war cries, and dance is
the Maori peruperu haka, versions of which have become
the trademark of Pacific Rim sports teams (notably
the New Zealand All Blacks). The war haka involves
swaying, stamping, grimacing, sticking out the tongue,
widening the eyes, grunting, crying, slapping the body,
and brandishing weapons. Originally it was performed
in unison to loosen up the body, promote solidarity, and
invoke victory from the war god Tumataueng; it was also
danced on the field to intimidate the enemy.
Such practices, documented in ancient Greece
and Akkadia (Burkert, 1992; Speidel, 2002, 2004) and
enacted today (Pieslak, 2009; Rosco, 2007), can provide
a physical advantage in the field. For instance, since the
16th century, when rhythmic drilling became standard
training in some cultures, soldiers who drilled routinely
defeated larger forces trained without drills (McNeill,
1995). Jordania (2011) cited the 19th-century example
of the Imam Shamil, military and spiritual leader of the
Dagestanian people, whose warriors had withstood an
International Journal of Transpersonal Studies23Going Berserk
80-day siege by the Russian empire, with losses in the
thousands on both sides. The few surviving Dagestanians
were surrounded and overwhelmingly outnumbered.
Instead of surrendering or fighting to the last man, Shamil
began singing and dancing a traditional dance until all his
fellows joined him. Accelerating the dancing and singing
to a peak, the Dagestanians broke out of their stronghold,
swords flashing and screaming war cries. Despite the
odds, the shock and ferocity of their attack prevailed, and
most of Shamil’s troop fought their way clear.
Jordania (2011) has argued that prehistoric
defensive, rhythmic, polyphonic singing was ubiquitous
because a very specific harmonic style, which creates a
loud, piercing, dissonant sound, is found among isolated
peoples in Asia, Africa, Europe, the Pacific Islands, and
South America. He further asserted that its function was
“to put our distant ancestors into a very specific altered
state of consciousness,” the advantageous “battle trance”
state (p. 98) characterized by: analgesia that reduces pain;
fearlessness; the neglect of personal survival instincts for a
group goal; and supernatural strength. Jordania postulated
that the increase in endorphins and oxytocin during a life-
threatening situation blocks pain and fear while amplifying
group trust and exhilaration at being part of a bigger
unity, a transpersonal identification. People can go into
battle trance suddenly and instinctively in high-demand
conditions (such as when a parent sees her child in a life-
threatening situation) or through deliberate cultivation
using ritual means. Today American soldiers in Iraq rely
on rock and heavy metal music played at deafening volume
to generate warrior spirit (Pieslak, 2009; Roscoe, 2007),
but in traditional societies, ritual cultivation of battle
trance was—and still is—the purview of warrior-shamans.
Berserkergang is a Norse pagan battle-trance
tradition, the latest descendent of an Indo-European
ecstatic warrior cult represented in the Rig Veda, the Iliad,
and Assyrian and Roman sources, among others (Kershaw,
2000; Speidel, 2002, 2004). Price (2002) relates the berserk
tradition to a circumpolar shamanic war-magic culture
spanning the Pacific northwest, Siberia, and Baltic and
North Sea, including the Sami peoples based on material
finds and oral history traditions, but its roots are well
established in other cultures. Berserkergang per se is known
from hostile Christian writers describing events centuries
old and poorly understood by the time they were recorded
in the 13th-14th centuries. Only one fragment (Eyrbyggja
saga, 28) may be traceable to heathen times, but even this
is doubtful (Simek, 1993). Christianity was mandated in
Iceland in 1000 CE, and berserks were outlawed by 1015
in Norway and by the Grágás, the medieval Icelandic legal
code. No organized berserk war-bands existed by the
13th century when Christian historian Snorri Sturluson
(1987, 1990) wrote down what he knew of the pagan oral
tradition before it was entirely wiped out, nor when even
later Christian transmitters recorded the sagas of events
occurring from 200-500 years earlier. By this time—and
by these sources—berserkers were stereotyped as either the
elite bodyguards and front-line shock troops of famous
kings, in keeping with their traditional high status as holy
champions (e.g., Egils saga Skalla-grímsonnar, Vatnsdæla
saga, Hrólfs saga kraka), or as uncouth, brutal outlaws who
forced duels on weaker opponents and/or demanded their
women (e.g., Grettis saga, Hervarar saga ok Heiðreks). Even
in the “outlaw” texts, scholars have discerned evidence that
the berserks were enacting ritual challenges to adolescent
males as part of a pagan warrior initiation ceremony,
including a death or ancestor cult (e.g., Blaney, 1972;
Danielli, 1945; Davidson, 1988, 1990; Hasenfratz, 2011;
Kershaw, 2000) misunderstood and distorted by Christian
transmitters. In fact, Indo-European sacred warriors had
been marked out from the rest of society by various means
for millennia, including by ritually distinctive grooming
(Kershaw, 2000; Miller, 1998) and being forbidden to own
land or farm (later confused with outlawry; Blaney, 1972;
Kershaw, 2000). Consecrated warriors were supported
by the community, especially the chieftain to whose
court they belonged, for centuries before the Viking Age
(Blaney, 1972; Kershaw, 2000). For instance, stories of
the berserk-style Irish heroes Cú Chulainn and Finn and
his warrior band reflect their right to take property and
women. Tacitus, writing of the Chatti tribe in 98 CE,
described sacred warriors’ duties and privileges:
Every battle is begun by these men. They are always in
the front rank, where they present a startling sight…
. None of them has a home, land or any occupation.
To whatever host they choose to go, they get their
keep from him…until old age leaves them without
enough blood in their veins for such stern heroism.
(Germania, 31)
The meaning of berserkergang can only be
appreciated within its culture, but given the bias of Christian
transmitters, earlier pagan observers of European battle
practices, like Tacitus, augment the record. Price (2002)
has argued convincingly for similarities among shamanic
traditions in circumpolar cultures ranging from Europe
International Journal of Transpersonal Studies24 Wade
to the Pacific Northwest, as Speidel (2002, 2004) did for
a Indo-European ecstatic warrior tradition in the heroic
mode from the second millennium BCE to the Viking
Age. Thus accounts and material finds from a variety of
sources support not only the ubiquity of this type of war
magic among northern European peoples but also provide
greater insight about how it was practiced.
Odin’s Warriors
Berserks were the warrior-shamans of Odin, god of
magic, poetry, battle, and death. His name comes
from the Old Norse óðr, which scholars have often glossed
as fury, after Adam of Bremen (a hostile missionary; Gesta
Hammaburgensis ecclesiae Pontificum 4.26), but which also
means mind, intelligence, or soul as well as poetry, eloquence,
and inspiration (e.g., Davidson, 1988, 1990; Simek, 1993;
Sturluson, 1987; from the proto-Indo-European root
*uat-). Odin is the god of mental powers and spiritual
awakening, not merely fury, which is only one form of
animating excitement.
Odin is a shapeshifter, as his numerous sobriquets
indicate, such as Many-Shaped, Swift-in-Deceit, and hard-
to-translate names that contain the root changing.
It was said that he understood such tricks of cunning
that he could change himself and appear in any form
he would….
Odin often changed himself; at those times his
body lay as though he were asleep or dead, and he
then became a bird or a beast, a fish or a dragon, and
went in an instant to far-off lands on his own or other
men’s errands. (Heimskringla, Ynglinga Saga, 6-7)
Limiting discussion to relevant portions of Odin’s
warrior magic for the scope of this paper, his powers
included: clouding the mind with fear and confusion, or the
reverse, instilling courage and mental clarity; weakening or
strengthening the body; magically constraining movement
(“the fetters”); breaking or strengthening weapons and
armor; and invulnerability magic. For example, Odin lists
some of his battle enchantments:
That third [spell] I know if my need be great
To fetter a foeman fell:
I can dull the swords of deadly foes,
That nor wiles nor weapons avail….
That fifth I know, if from foeman’s hand
I see a spear sped into throng,
Never so fast it flies but its flight I can stay,
Once my eye lights on it.
(Hávamál, 148, 150; Hollander’s translation)
Odin’s magic was shared by his warrior-shamans:
In battle Odin could make his foes blind or deaf or
terrified and their weapons were as nothing more than
sticks; but his own men went about without armour
and were mad like hounds or wolves, and bit their
shields and were strong as bears or bulls; they slew
men, but neither fire nor steel would deal with them.
This was called a berserk’s-gang. (Heimskringla,
Ynglinga Saga, 6)
Scholarly opinion (e.g., Blaney, 1972; Geraty,
2015; Price, 2002; Guðmundsdóttir, 2007) has remained
hopelessly divided about whether berserk means bare of
shirt (sark) for fighting without armor or completely bare-
chested; or bear-shirt for the donning of animal skins in
a shamanic rite of transformation. Odin’s warriors were
likened to bears (single-combat champions? Davidson,
1988, 1990; Speidel, 2002, 2004) and to wolves (ùlfheðnar,
wolf-skins often translated as wolf-warriors, who fought
as a group? Davidson, 1988, 1990; Price, 2002; Speidel,
2002, 2004), Odin’s totem animal. Both berserks and
ùlfheðnar represent the same battle trance, regardless of
combat style.
Berserkergang reflects a strong Indo-European
war sorcery heritage involving: stunning the enemy
with terror; rendering their weapons harmless; scorning
to wear armor; shapeshifting into predator forms; and
invulnerability to fire and blades (Speidel, 2004). (The
formulaic language referring to berserks, á þá bitu eigi
járn, translates as “iron would not bite them,” e.g., Egils
saga Skalla-grímsonnar, 9; Grettis saga, 2.) According to
Speidel (2002), the earliest description of this kind of war
magic occurred in a poem celebrating the victory of the
Assyrian Tukulti-Ninurta over the Babylonians in 1228
BCE: They are furious, raging, taking forms strange as
Anzu [a magical bird-god].
They charge forward furiously into the fray without
armor, They had stripped off their breastplates, discarded
their clothing, They tied up their hair and polished (?) their…
weapons, International Journal of Transpersonal Studies25Going Berserk The fierce heroic men danced with sharpened weapons. They blasted one another like struggling lions, with eyes aflash (?), While the fray, particles drawn in a whirlwind, swirled around in combat. (p. 255)
Odin determines the outcome of battles, and
with the Valkyrie goddesses, selects the outstanding
heroes among the slain who deserve glorious afterlife
in Valhalla disporting themselves until they will fight
the forces of evil at the cataclysmic battle of Ragnarök.
Heroes were immortalized on the earthly plane by having
their deeds sung in poetry so that their memories never
perished. The desire for everlasting fame commemorated
in poetry was a prime motive for Indo-European warriors
(e.g., Duchesne, 2009; Fortson, 2010; Gurevich, 1995;
Poliakoff, 1987Speidel, 2004). Champions engaged
in conspicuous acts of bravery, laughing at danger and
scorning to protect themselves—especially in conditions
of certain death—to win immortality.
To fight in such a [berserk] style was a ritual, acting
out a myth. Groups of wolf-warriors and berserks had
their own weapons, tactics, and war dances….Their
excesses meant glory: Wolf-warriors, berserks…no
doubt won the “unwilting glory” held out by the
Iliad and the Rig-Veda. (Speidel, 2004, p. 193)
Berserks held the most valued and dangerous
roles in armed forces, serving in the king’s bodyguard
and/or in the vanguard. The earliest historical account
of berserks was written in the ninth century by Harald
Hairfair’s court skald (poet) Þorbjo' rn hornklofi
describing the king’s consolidation of Norway and his
deployment of berserks as shock troops. It is one of the few
contemporary accounts since most were recorded from
oral traditions centuries after the events they describe by
Christians to whom the old ways were incomprehensible
and anathema. In one section, the poet uses the device
of a dialogue between a Valkyrie, a warrior-goddess
associated with Odin, and a raven, Odin’s familiar and
battlefield scavenger. The Valkyrie asks the raven:
“Of the berserkers’ lot would I ask thee, thou who batten’st on corpses: how fare the fighters who rush forth to battle,
and stout-hearted stand ‘gainst the foe? “Wolf-coats they are called, the warriors unfleeing, who bear bloody shields in battle; the darts redden where they dash into battle and shoulder to shoulder stand. ‘Tis men tried and true only,
who can targes [shields] shatter, whom the wise war-lord
wants in battle.” (Hrafnsmál, 20-21) The later Icelandic sagas reflect the key roles of the berserks and their prowess on the field, although by this time berserks are stereotyped and demonized to a greater or lesser degree (Price, 2002). “Then the king cried on his bearserks [sic] for an onslaught, and they were called the Wolf-coats, for on them would no steel bite, and when they set on naught might withstand them” (Grettis saga,
2). Angrim’s sons “were all of them berserks…. And they
were never in a battle they didn’t win. Because of this,
they became famous in all the lands, and there wasn't a
king who did not give them what they wanted” (Hervarar
saga ok Heiðreks, 2). Elsewhere a band of berserks was sent
to eliminate enemy soldiers on a long ship:
[Kveldulf] then had a fit of shape-strength [i.e., went
berserk, involving shapeshifting], as had also several
of his comrades. They slew all that came in their way,
the same did Skallagrim where he boarded the ship;
nor did father and son stay hands till the ship was
cleared. (Egils saga Skalla-grímsonnar, 27)
Even taking into account the stereotyping of
Christian writers about berserks, the use of ecstatic warriors
as elite shock troops has a long heritage (Duchesne, 2009;
Speidel, 2002; Reid, 1998), so these late accounts retain
elements of truth. The Greeks and Romans by their
classical periods were beginning to abandon their own
sacred warrior styles for well regulated, massed fighting and
to distance themselves from battle trance as “barbarian”
tactics, which they viewed as restricted to the “blond
nations” by the sixth century CE (Speidel, 2004, p. 194).
Northern Europeans practiced it until technological and
strategic advances—as well as Christianity—rendered
it ineffective. But before then, these holy warriors were
greatly revered, and a vestige of this regard even survived
into a late religious romance, the 13th century Barlaams
ok Josaphats saga that calls Jesus God’s “young berserk”
International Journal of Transpersonal Studies26 Wade
(“hinn vgni berserkr guðs”) and his twelve disciples “his
berserks” (197). Berserkergang, even when rendered as
battle-fury or -madness, meant something hallowed:
being possessed by Odin (e.g., Kershaw, 2000). Berserks
were his consecrated warriors, dedicated to a life of
privation and the ultimate self-sacrifice to serve him and
their communities and attain everlasting life.
Going Berserk
The act of becoming berserk features the classic
dimensions of war magic. Taunting to work up
anger prior to an engagement was a part of a refined
flyting convention between opposing champions in pagan
European culture (e.g., Sayers, 1991). (Flyting is a ritual
contest of insulting an opponent in a way that displays
verbal virtuosity, such as rap today.) Greek historian
Diodorus Siculus (90-30 BCE) said of the Gauls:
It is also their custom, when they are formed for
battle, to step out in front of the line and to challenge
the most valiant men from among their opponents
to single combat, brandishing their weapons in front
of them to terrify their adversaries. And when any
man accepts the challenge to battle, they then break
forth into a song in praise of the valiant deeds of their
ancestors and in boast of their own high achievements,
reviling all the while and belittling their opponent,
and trying, in a word, by such talk to strip him of his
bold spirit before the combat. (The Library of History,
5.29)
In Brennu-njal’s saga (118), Skapheðinn insults
Skapti Þorodsson’s intelligence, courage, and appearance.
Beowulf (literally Am-a-Wolf, a typical berserker name)
engages in a flyting provoked by Unferth, who sneers
that Beowulf, who could not best a man named Breca in
a swimming match, will never prevail over the monster
Grendel (Beowulf, ll. 506-528). Beowulf, after saying
that he had slain nine sea-monsters during the swimming
contest, taunts:
Now, I cannot recall
Any fight you entered, Unferth,
That bears comparison. I don’t boast when I say
That neither you nor Breca ever were much
Celebrated for swordsmanship
Or for facing danger on the battlefield.
You killed your own kith and kin,
So for all your cleverness and quick tongue,
You will suffer damnation in the pits of hell [Christian
bowdlerization].
The fact is, Unferth, if you were truly
As keen or courageous as you claim to be
Grendel would never have got away with
Such unchecked atrocity, attacks on your king….
But he knows he need never be in dread
Of your blade….
He knows he can trample down you Danes
To his heart’s content, humiliate and murder
Without fear of reprisal. But he will
find me different. (ll. 582-601)
European pagan warriors routinely used noise-
making tactics alone or with dancing to bring on battle-
trance and frighten opponents. According to Livy (64?
BCE-17 CE), Celtic fighters sang and danced to provoke
fear: “Their songs as they enter into battle, their war-
whoops and dances, and the horrible clash of arms as
they shake their shields in the way their fathers did before
them—all these things are intended to terrify and appall”
(The History of Rome, 38.17). Tacitus referred to the songs
Germanic warriors sang before battle, especially a chant,
by which
they not only kindle their courage, but, merely by
listening to the sound, they can forecast the issue of
an approaching engagement. For they terrify their
foes or themselves become frightened, according
to the character of the noise they make upon the
battlefield; and they regard it not merely as so many
voices chanting together but as a unison of valor.
What they particularly aim at is a harsh, intermittent
roar; and they hold their shields in front of their
mouths, so that the sound is amplified into a deeper
crescendo by the reverberation. (Germania, 3)
Berserks not only held their shields in front of
their mouths, but also bit down on the iron rim of the
shield as part of their battle trance. Bears snort and clack
their teeth when on the defensive, and berserks made the
same sound by biting on their shields’ metal rims (Speidel,
2004, p. 45). “And as he came forward on the field to the
ground of combat, a fit of Berserk [sic] fury seized him; he
began to bellow hideously, and bit his shield” (Egils saga
Skalla-grímsonnar, 67). The rooks of a 12th century chess
set from the Hebrides are warriors biting their shield rims.
In particular, berserks were known for howling
like animals in battle trance: “Now bearserks'-gang [sic]
International Journal of Transpersonal Studies27Going Berserk
seized them, and they howled like dogs” (Grettis saga, 19).
Greek historian Leo the Deacon was an eyewitness of the
Byzantine emperor’s Bulgarian campaigns in 970-971
CE against Rus’ warriors fighting in berserk style. The
Rus’, whose culture is closely associated with the Norse or
Varangian peoples and whose name is retained in Russia
and Belarus, unnerved seasoned Byzantine troops by
“roaring like beasts and uttering strange and weird howls,”
according to Leo (History, 8.4), and their leader Sviatoslav I
of Kiev is described as “charging the Romans in a frenzied
rage” (History, 9.8). The earliest Norse record of berserks
commemorated Harald Hairfair’s victory at Hafursfjord
around 872 CE:
The berserks bellowed
as the battle opened,
The wolf-coated shrieked loud
and shook their weapons.
(Hrafnsmál,8; also cited in Heimskringla, The History
of Harald Hairfair, 18)
Archeological finds throughout northern Europe
have shown war dancing involving the ritual donning of
animal skins and masks and leaping with weapons prior
to battle as a shapeshifting device (e.g., Davidson, 1990;
Price, 2002; Speidel, 2004). Scandinavian, British, and
German sites have yielded ornamental plates from helmets,
scabbards, and buckles depicting warriors dancing naked
along with warriors clad in animal skins brandishing
swords and spears. For example, a die dated to about 600
CE from Torslunda shows a naked dancer, probably Odin,
wearing only a horned helmet and sword-belt waving a
spear in each hand followed by a man completely covered
by a wolf skin and mask except for his human feet and
hands, one of which clutches a spear while the other draws
a sword from its scabbard. The wolf’s raised head with
jaws agape seems to be howling. Tacitus (Germania, 6)
reported youths dancing naked in and out of spears and
swords pointed at them, and a legacy of weapon dances
persisted well into the 19th century in Germany and the
British Isles (Kershaw, 2000).
Dancing, singing, howling, and donning animal
skins in Norse war magic conferred the animal’s strength
and speed on the shamans. Transformation into beasts by
wearing animal pelts and masks has been well established
in Indo-European culture (Cebrián, 2010; Kershaw,
2000; Price, 2002; Speidel, 2002, 2004). It was inherent
in the terms berserk and ùlfheðinn, and in the personal
names of warriors, which included the element for bear
and wolf, such as Gunbjorn, Thorbjorn, Wulfgang, and
Hildulf, respectively (e.g., Kershaw, 2000). Berserks were
specifically called shapeshifters, eigi einhamr (not of one
shape) or hamrammr (shape-strong; Blaney, 1972, p. 39).
The degree to which their transformation was
regarded as psychic or physical is unknown. Ecstatic
dancing and fighting in animal skins seem to have
conferred certain supernatural and feral qualities on
berserks, but they seem to have remained essentially
human. Two marked exceptions exist in the earlier,
more legendary literature in which no dancing was
involved and people actually did become animals. The
celebrated hero Sigmund and his son Sinfjotli appear to
have become werewolves to avenge their dead kinsmen
in the Poetic Edda (Helgakviða Hundingsbana I, 36-37).
They found magic wolf skins, and when they put them
on, they could not get them off, during which time they
communicated in the voice and language of wolves and
hunted like them (Volsunga Saga, 8). Each could kill up to
seven men alone, and Sigmund forbade his son to attempt
more, but Sinfjotli once successfully killed eleven. After a
certain number of days, the skins came off. They burned
them and thereafter remained in human guise but with
increased lethal powers. The most famous bear warrior,
known from multiple sources, is Boðvar Bjarki, who, like
Odin, bi-located in a shapeshifting trance. His human
body was observed apparently sleeping in the hall while a
giant bear fought in King Hrolf Kraki’s bodyguard on the
battlefield, perceived not only by Boðvar’s comrades but
also by the enemy:
Then Hjorvard and his men [the enemy] see a huge
bear going before the King Hrolf's men, always
nearest to where the king was. He kills more men with
his paw than any five of the king's other champions.
Blows and missiles glance off him. But he bursts under
him both men and horses of King Hjorvard's army;
and everything that comes in his way, he crushes in
his teeth, so that panic sweeps King Hjorvard's army.
(Hrólfs saga kraka, 50).
When Boðvar was awakened from the trance,
the bear disappeared. As a man, Boðvar fought in
berserkergang, but less effectively than as the bear when
he was in the trance.
Consistently in the earlier literature, berserkergang
was cultivated through certain techniques prior to conflict
or evoked by highly emotional events. However, the later,
more Christianized sources began to suggest otherwise.

For instance, both Kveldulf, who was “very shape-strong”
and whose name meant Evening Wolf, and his son became
stronger and more belligerent as daylight waned, so people
avoided them then (Egils saga Skalla-grímsonnar, 1). In
another saga, a man named Thorir who felt compromised
‘“because a berserk fury always comes over me when
I would least wish it to’” (Vatnsdæla saga, 37) would do
anything to get rid of it. Prayers to the Christian god
and keeping a vow succeeded so that “a berserk fit never
again came over Thorir” (Vatnsdæla saga, 37). It is hard to
know how to take these sources because of their bias and
distance from the original events.
The Berserk State
In combat the berserk state was characterized by
supernatural strength, fearlessness, and invulnerability.
Even in a literature describing a time when fighters routinely
hacked one another with halberds, spears, swords, and
axes, it is possible to gauge extraordinary feats of strength.
They are reported with sufficient detail and in so many
records from different sources that they undoubtedly
reflect eyewitness accounts of real events, even if not those
ascribed to a particular actor. For example, Kveldulf
“brandished high his battle-axe, and smote Hallvard right
through helm and head, so that the axe sank in even to the
shaft; then he snatched it back towards him so forcibly that
he whirled Hallvard aloft, and slung him overboard” (Egils
saga Skalla-grímsonnar, 27). The Rus’ prince Sviatoslav I
of Kiev managed to escape capture by Byzantine troops in
971 CE even though he had “lost a lot of blood and been
stricken by many arrows,” according to hostile eyewitness
Leo the Deacon (History, 9.10). In 1066, the Anglo-
Saxons surprised the invading Norwegians at the River
Derwent and began cutting them to pieces as they fled
over Stamford Bridge to their camp. The Vikings sent a
single berserk to hold the bridge and buy time. The bridge
was wide enough for four men abreast, yet the champion
held it alone with his battle-axe for hours, slaughtering all
comers. William of Malmesbury (1847) echoed the awe
this hero inspired among the enemy:
Yet, however reluctantly posterity may believe it, one
single Norwegian for a long time delayed the triumph
of so many, and such great men. For standing on the
entrance of the bridge…after having killed several
of our party, he prevented the whole from passing
over. Being invited to surrender, with the assurance
that a man of such courage should experience the
amplest clemency from the English, he derided those
who entreated him; and immediately, with stern
countenance, reproached the set of cowards who were
unable to resist an individual. (p. 256)
As bodies choked the bridge, one of the Anglo-
Saxons realized it was useless to meet this juggernaut
head-on, so he launched a boat underneath the bridge, and
jammed his spear up between the boards of the bridge,
killing the hero. The lone Viking “stayed the advance of
the whole English army till the ninth hour,” killing forty
and wounding countless others, and even his enemies
believed that his “name ought to have been preserved”
(Henry of Huntingdon, 1853, p. 209)—alas it was not.
Stripping before or during battle signaled
fearlessness (Kershaw, 2000; Speidel, 2002, 2004). Fighters
would throw off their armor and even their clothes in front
of the enemy to demonstrate courage, disdain for the
opponent, and love of glory. In addition, it signaled that
the warrior had invoked powerful invulnerability magic.
According to Polybius (200-118 BCE), the Celts
“calculated to inspire terror” among the legions by tossing
their clothing away and moving into the front lines naked
except for their weapons (Histories, 2.28). Diodorus
Siculus observed of the Gauls: “Certain of them despise
death to such a degree that they enter the perils of battle
without protective armour and with no more than a girdle
about their loins” (The Library of History, 5.29). Germanic
berserks, barefooted and bare-chested except for animal
skin cloaks, are honored for fighting in the Roman
emperor’s bodyguard on Trajan’s column (Speidel, 2002,
2004). Norway’s king Hacon the Good was Christian,
but when surprised and badly outnumbered by an enemy
army in 961 CE, he took the berserk approach:
Flung off his war clothes,
Slipped off his byrnie,
Before he began.
The gladdest of fighters…(Heimskringla,
The History of Hacon the Good, 32)
Laughing at danger, like discarding armor,
especially when defeat and death seemed inevitable, was a
bid for Valhalla and fame. When Byrhtnoth, the Anglo-
Saxon leader of the battle of Maldon, was impaled by a
Viking spear, he pushed his shield hard enough against
it to break off the shaft, killed his attacker with a spear-
thrust through the neck, and then slew another by driving
his spear through his mail coat and into his heart:
International Journal of Transpersonal Studies29Going Berserk
The earl was the blither:
the brave man laughed then, said thanks to Metod
[Christian God]
for the day-work God gave him.
(The Battle of Maldon, ll. 146-148)
Similar to fighting bare-chested was discarding
one’s shield in battle or wearing it on the back instead of in
front (Speidel, 2002, 2004). In the Viking version of the
battle of Brunanburh in 937 CE,
Then Thorolf became so furious [berserk] that he cast
his shield on his back, and, grasping his halberd with
both hands, bounded forward dealing cut and thrust
on either side. Men sprang away from him both ways,
but he slew many…. He slew the man who bore the
earl's standard, and cut down the standard-pole. After
that he lunged with his halberd at the earl's breast,
driving it right through mail-coat and body, so that it
came out at the shoulders; and he lifted him up on the
halberd over his head, and planted the butt-end in the
ground. There on the weapon the earl breathed out his
life in sight of all, both friends and foes. Then Thorolf
drew his sword and dealt blows on either side, his men
also charging. (Egils saga Skalla-grímsonnar, 53)
Two-handed sword or spear work in the text
indicates that the warrior has discarded his shield (Speidel,
2004). For example, Asmund went berserk and sang,
“‘Now without shield let us ply our warfare bare-breasted,
with flashing blades….’ When he had said this, he gripped
his hilt with both hands, and, fearless of peril, swung his
shield upon his back and slew many” (Saxo Grammaticus,
The Danish History, 1). At Stamford Bridge, Harald
Hardrade “grew so heated [berserk] that he rushed
forth right out of the line and struck with both hands;
then neither helm nor byrnie could stand against him”
(Heimskringla, The History of Harald Hardrade, 92).
In battle trance, berserks were invulnerable to fire
and blades. Imperviousness to fire is attested in two forms:
the ability to swallow live coals and to walk through fire.
Sivald’s seven berserk sons “were such clever sorcerers that
often, inspired with the force of sudden frenzy [berserk],
they would roar savagely, bite their shields, swallow hot
coals, and go through any fire that could be piled up….”
(Saxo Grammaticus, The Danish History, 7).
Invulnerability to bladed weapons was sometimes
attributed to animal skins worn into battle. According to
one account of the battle of Stiklestad (1030 CE), Tore the
Hound (Thorir hund) and his band of berserks wore magic
reindeer coats made by the Sami, who were considered
master wizards, “and the king’s sword would not bite
where it struck the reindeer skin coat” (Heimskringla, The
History of King Olav, 228). But in an earlier version, the
Sami-crafted coats were made of wolf skins, “And men
say that Bjorn the Stout hewed with his sword at Thorir
that day. Yet wherever he attacked his sword refused to
bite as though its edge had been turned” (Heligasaga Ólafs
konungs Haraldssonar, 91, cited in Blaney, 1972, p. 86).
Usually it is impossible to tell what berserks
are wearing, but they cannot be cut. “When the roll of
Harold's army was called, many were they that had fallen,
and many were sore wounded…nor was there a man
unwounded in the king's ship before the mast, except
those whom iron bit not, to wit the Berserks” (Egils saga
Skalla-grímsonnar, 9). In one epic battle two berserks Egil
and Atli “went at it with a will, blow upon blow,” and
hacked their shields to pieces.
And when Atli’s shield was of no use, then he cast it
from him, and, grasping his sword with both hands,
dealt blows as quickly as possible. Egil fetched him a
blow on the shoulder, but the sword bit not. He dealt
another, and a third. It was now easy to find parts in
Atli that he could strike, since he had no cover; and
Egil brandished and brought down his sword with all
his might, yet it bit not, strike where he might. (Egils
saga Skalla-grímsonnar, 68).
So effective was this invulnerability magic that
berserks were said to blunt their enemy’s blades with
sorcery (e.g., Saxo Grammaticus, The Danish History, 7)
like Odin (Poetic Edda, Hávamál, 148). Nevertheless
its limitations were exploited by contemporaries, usually
with blunt-force weapons, at least according to Christian
sources. For instance, Halfdan, knowing that Hakon
could dull swords with spells, made a huge mace to club
him to death (Saxo Grammaticus, The Danish History,
7). Bludgeoning, Christian magic, and the limitations
of fire invulnerability were combined in a story from
several sources. An Icelander named Thorkell wanted to
kill two berserks who “walked barefoot on burning coals”
(Vatnsdæla saga, 46), and agreed to convert to Christianity
if Bishop Fredrek would help him do it. The bishop had
Thorkell build three fires on the floor of the hall, which
he hallowed in the name of the Christian god. He told
Thorkell to surround the fires with benches full of brave
fighters armed with clubs, “For no iron bites them, and thus you shall beat them to death” (Vatnsdæla saga, 46).
The berserks walked through the first fire unscathed, but
the second one began to burn them, and when they tried
to step out onto the floor the warriors on the benches
bludgeoned them to death.
When berserks fought each other in single combat,
they tried to bypass their opponent’s invulnerability.
Leading his berserk band on horseback and wearing an
unfastened helmet, Snaekoll challenged an old farmer
to give them his daughter. Grettir, a berserk, who was
accompanying the farmer, refused, found a way to wound
Snaekoll severely early in the trance state and then kill
him.
[Snaekoll] began to howl and to bite the rim of his
shield. He held the shield up to his mouth and scowled
over its upper edge like a madman. Grettir stepped
quickly across the ground, and when he got even with
the berserk's horse he kicked the shield with his foot
from below with such force that it struck his mouth,
breaking the upper jaw, and the lower jaw fell down
on to his chest. With the same movement he seized
the viking's helmet with his left hand and dragged
him from his horse, while with his right hand he
raised his axe and cut off the berserk's head. (Grettis
saga, 40)
Beowulf’s duel with Grendel was hand to hand.
“Not blade on earth, no blacksmith’s art / Could ever
damage” Grendel who “had conjured the harm from
the cutting edge / Of every weapon” (Beowulf, ll. 801-
804), so Beowulf, after a terrible struggle, dealt Grendel
a fatal wound by tearing off his arm, including part of
the shoulder (ll. 816-821). In the duel above, when Egil’s
sword would not bite Atli, he threw down his arms, “and
bounding on Atli, gripped him with his hands. Then the
difference of strength was seen, and Atli fell right back,
but Egil went down prone upon him and bit through his
throat. There Atli died” (Egils saga Skalla-grímsonnar, 68).
In the battle trance, berserks could not always
distinguish between friends and foes. In one account (Egils
saga Skalla-grímsonnar, 40), Grim, subject to wolfishness
toward evening, was playing ball late in the day, and in
the heat of competition, killed one of his opponents and
started to come after his own son in such a frightening
way that a servant-woman intervened. He killed her.
Except in the heat of battle, it took time to work
up to the battle trance, which did not last forever; when
the state wore off, warriors were unusually vulnerable.
It is said of shape-strong men, or men with a fit of
Berserk fury on them, that while the fit lasted they
were so strong that naught could withstand them; but
when it passed off, then they were weaker than their
wont. Even so it was with Kveldulf. When the shape-
strong fit went from him, then he felt exhaustion from
the onset he had made, and became so utterly weak
that he lay in bed. (Egils saga Skalla-grímsonnar, 27)
Not surprisingly, people waited for post-combat
exhaustion to overcome berserks before trying to kill them
(e.g., Hervarar saga ok Heiðreks, 4; Eyrbyggja saga, 28)
Explanations of Berserkergang.
Berserkergang is so well attested in the historical and
legendary accounts that it has attracted a fair amount
of scholarly attention, virtually none of it transpersonally
oriented, to account for its unusual effects. Most
explanations involve the ingestion of psychotropic drugs,
with present-day touchstones being the superhuman
strength demonstrated by people resisting restraint,
commonly called excited delirium syndrome (EDS). EDS
is a controversial diagnosis because it is usually given post-
mortem. Neither the American Medical Association nor
the American Psychological Association recognize it as
a medical or mental health condition, but the National
Association of Medical Examiners has recognized it for
more than twenty years, especially in accounting for the
sudden death of violent individuals whose restraint did not
involve mechanical cause of death (such as asphyxiation
from a chokehold). The American College of Emergency
Physicians has also recognized EDS since 2009 (Flosi,
2011). EDS is characterized by bizarre, violent, and
agitated behavior; combativeness; altered mental states
and delirium; shouting; hyperactivity; extreme endurance
and unusual strength; and autonomic dysregulation,
including hyperthermia (raised body temperature)
and sweating (Gill, 2014; Ross & Chan, 2006) usually
followed by sudden death. Its precursor was Bell’s mania,
first described in 1849 (Benzer, Najad, & Flood, 2013)
among the institutionalized insane. Most modern
documentation comes from the autopsies of detainees who
died suddenly in police custody, and the post-mortems
typically show long-term use of drugs not available in
the ancient world, especially cocaine and amphetamine
in various forms (Flosi, 2011; Gill, 2014) often in
combination with alcohol, other recreational drugs, or
excessive pharmaceutical drugs.
International Journal of Transpersonal Studies31Going Berserk
A related but non-delusional state, hypomania,
is one of a range of poorly understood manic states in
which people exhibit extraordinary powers, whether
euphoric or aggressive, yet do not require hospitalization
or result in catatonia or death (Lee, Huang, Hsu, & Chiu,
2012). Hypomania is characterized by inflated self-esteem
or grandiosity, decreased need for sleep, talkativeness,
distractability, increased involvement in goal-directed
activities, and either elevated or irritable mood in the
absence of hallucinations or delusions (APA, 1994).
Hypomania, while far more congruent with aspects of
berserkergang, like EDS, is considered an involuntary
state, rather than one deliberately induced.
The dominant theory is that berserkergang was
produced by consuming the hallucinogenic mushroom
Amanita mascaria (fly agaric), an idea introduced
in 1784 by Samuel Lorenzo Ödman without much
evidence (Wasson, 1968). The hardihood of this falsity
is attributable to a canard presented at an American
Psychiatric Association conference and later published
by physician Howard D. Fabing (1956). While the
possibility of drugs cannot be dismissed in the limited
situations when such preparation was possible (prior
to battle), it is difficult to comprehend why Fabing’s
argument continues to be influential, despite glaring
flaws: 1) Fabing cited no primary Viking Age sources
and referred to a character named Berserk, who does not
exist in the literature; 2) he drew spurious comparisons,
noting that Siberian tribes used Amita muscaria
“orgiastically” (not in combat) and reported “prodigious
feats of physical strength” (1956, p. 232), as though
their behavior inexplicably bears on Norse warriors; 3)
Fabing cited research that Amanita mascaria produces
dilated eyes, convulsive gestures, visual and auditory
hallucinations, singing and dancing (Jochelsen, cited in
Fabing, 1956, p. 232) and “explosive diarrhea, profuse
sweating, excessive salivation and vertigo” as well as
complete disorientation, irrationality, and violence
(Drew, cited in Fabing 233)—all of which would
render a warrior unfit for combat; 4) he stated that
bufotenine, the active ingredient of some poisonous
toads, trees and seeds (none native to Europe or Iceland,
nor related to Amanita muscaria), also brought on
berserkergang because when he injected bufotenine into
subjects—a technology not available to berserks—their
faces darkened and they became “relaxed and languid”
with severely impaired spatial perception (p. 236),
symptoms contrary to those of fly agaric intoxication,
to berserkergang, and to combat. Fabing aside, all fly
agaric mushrooms are known for the unpredictability of
their effects, depending on the variety, habitat, amount
ingested, and individual metabolism (persons with the
same body weight taking similar doses have very different
reactions; Benjamin, 1992; Buck, 1963; Hoegberg,
Larsen, Sonne, Bang, & Skanning, 2008; Satora,
Pach, Butryn, Hydzik, & Balicka-Slusarczyk, 2005).
Symptoms include nausea, twitching, drowsiness, drop
in blood pressure, sweating, salivation, auditory and
visual distortions, mood changes, euphoria, relaxation,
ataxia, and loss of equilibrium. Large doses can
produce agitation, confusion, irritability, hallucinations,
and seizures. Even if ingestion selectively sharpened
perceptions and reflexes or heightened aggression—the
opposite of what is suggested—the extreme variability
and unpredictability in response would mitigate against
it for combat.
Other intoxicant arguments are similarly flawed.
Wernick (1979) suggested that berserks were drunk on
alcohol, which may have included bog myrtle (Myrica gale
or Gale palustris), a plant used in Scandinavia to flavor
alcoholic beverages. Drunkenness does not conduce to
effective fighting, and bog myrtle, an abortificant that
causes gastric upset and severe headaches in large doses,
would further reduce battle fitness. Drug arguments
are frequently used to rationalize outstanding warrior
feats by the losing side, with similarly little grasp of
combat demands, toxicology, and extraordinary human
capability. The British, for example, alleged that spear-
toting Zulu warriors defeated them at Isandlwana
because the Zulus ate dagga (marijuana), which rendered
them fearless and trancelike in the face of the imperial
forces’ technologically superior breech-loading rifles,
rockets, and small cannons (Booth, 2003). Marijuana is
not a stimulant, but even today confusion is propagated
by “forensic battle experts,” such as Ian Knight (2011)
who specializes in South African historical battles
and alleges that tetrahydrocannabinol (THC), the
most psychoactive ingredient in cannabis, produces
frenzy. THC may increase anxiety and reduce physical
discomfort, which would be useful in battle, but it also
impairs coordination, reaction time, and concentration
(e.g., Heishman, Huestis, Henningfield, & Cone, 1990).
The most intelligent arguments have ascribed the combat
ingestion of psychotropic substances to a desire to
obscure full realization of the horrors of battle (Roscoe,
2007) rather than to improve fighting capabilities.
International Journal of Transpersonal Studies32 Wade
Other explanations for berserkergang have
included self-induced hysteria poorly distinguished from
self-induced ecstatic states but described as a pathology),
epilepsy, mental illness, or genetic flaws (Byock, 1995;
Carlson, 2006; Foote & Wilson, 1970), but none accounts
for more than a fraction of the Norse data, much less for
historical accounts of similar pagan ecstatic warriors from
different cultures. Geraty (2015) advanced a theory that
“berserk behavior is due to heightened exposure to extreme
violence, otherwise known as post-traumatic stress disorder”
(p. 11), based on comparisons with psychiatrist Jonathan
Shay’s (1994) book Achilles in Vietnam, regarding his work
with American veterans of the Vietnam War. As brilliant
as Geraty’s analysis is in some areas, many comparisons just
do not hold up beyond universal behaviors seen in combat.
Her most cogent argument was that some of the later-
documented berserks and traumatized veterans exhibited
persistent hypervigilance and potential for explosive
violence when no longer in combat. Such a judgment is
somewhat difficult to assess owing to the bias of Norse
sources and a cross-cultural gap spanning a millennium:
given the unpredictable, ubiquitous violence of medieval
societies, aggressive hypervigilance was, in fact, appropriate
and highly adaptive, including for noncombatants.
The APA has confused and pathologized
berserkergang with comparisons to other poorly understood
states from different cultures. The last three Diagnostic and
Statistical Manuals (DSM; APA, 1980, 1994, 2013) have
listed a category called intermittent explosive disorder
(IED) likened to berserkergang and other “culture-bound
syndromes,” such as the Malaysian amok, with which
berserkergang is clinically compared (APA, 1994, p. 845;
i.e., “going berserk” and “running amok”). Culturally-
bound syndromes were dropped from the DSM-5 as
a category. IED, poorly defined (e.g., Ahmed, Green,
McCloskey, & Berman;, 2010; Parzen, 2003), is considered
a disruptive impulse control and conduct disorder
characterized by unpremeditated explosive outbursts of
rage disproportionate to the situation, which may happen
more or less chronically and frequently, or with relatively
infrequent, high-intensity outbursts resulting in injury
or destruction of property (APA, 1980, 1994, 2013). An
illustration given of the way the APA understands amok,
similar to the way it regards “going berserk,” was that of a
Filipino man who, upon learning that his wife was having
an affair, killed her parents, injured her and their son,
and then set fire to the house of his wife’s lover’s brother,
which killed two children living there (Parzen, 2003, p.
142). IED and the related culturally-bound conditions
as defined by the APA match little in the primary berserk
sources.
Anthropologists of war magic provide much more
valid insights for berserkergang, especially the spiritual
foundations of war magic in general. Southeast Asian
cultures, for example, have an ecstatic champion tradition
very similar to the Indo-European heritage. “Amok, far from
being an individual, disorganized and insane activity”—as
it, and going berserk, are now understood popularly and by
the APA—was a “coordinated, group form of violence…
unleashed through invulnerability rituals” (Farrer, cited in
Reid, 1988, p. 125). The Javanese, noted for ferocity in
combat, used a vanguard of amok warriors as shock troops
to intimidate, scatter, and kill the enemy in the opening
moves of a battle (Reid, 1988). Amoks, after cultivating
a trancelike state of invulnerability through elaborate
spiritual and martial arts rituals, furiously charged the
enemy, slashing with swords and krises. Even the Balinese,
whose strategies relied more on systematic formations, used
amoks, who wore white to symbolize their self-sacrifice, in
leading the attack. If these initial amok attacks succeeded
in killing the enemy leader, it was often enough to decide
the battle before the regular troops were engaged.
Although cross-cultural shapeshifting magic
lags in systematic research, the invulnerability claims of
berserkergang now have considerable backing. In fact,
invulnerability demonstrations have figured prominently
in almost all religions since ancient times (e.g., Boles,
1997; Kane, 1982; William & Hood, 2015). Fire-
walking, common to many religions as a demonstration
of attainment, is now a popular activity at Western self-
development seminars bolstered by intense group bonding,
singing, and dancing. Silat, the foundational martial art of
southeast Asia, retains its spiritual basis, as do most other
Asian martial arts. Invulnerability is considered a sign of
spiritual attainment, including fire-walking, eating broken
glass, climbing barefoot up a ladder of knives, and dipping
one’s hands into cauldrons of scalding water, boiling oil,
or molten tin (Crystal & Yamashita, 1987; Farrer 2009;
Waterson 1995). Public displays involve withstanding
blows from iron spikes, washing in sulfuric acid, slicing
one’s tongue with a machete without shedding blood, and
regurgitating live bats “without suffering any physical
harm” (Wilson, cited in Nilan, Demartoto, & Wibowo,
2014, p. 74). Silat folklore describes techniques that
allow the fighter to attack from afar using energy alone
without physically touching the opponent (Farrer, 2009),
International Journal of Transpersonal Studies33Going Berserk
similar to Boðvar Bjarki’s bi-location, something modern
athletes and martial artists attest (M. Murphy, personal
communication, October 8, 2015).
North African Isawiyya Moslem sects are noted
for “eating fire and cutting themselves in ecstasy” (Brett,
1988, p. 38). Adherents give public displays of trance-
dancing, slashing their torsos or heads as a sign of devotion
and personal relationship with saints (Crapanzano, 1973).
According to an early account, becoming-animal was also
involved:
Moreover, the human body can only endure
so much, as the overwhelmed berserks’ deaths indicate.
Zatsiorsky (2006) has calculated the theoretical
maximum an individual’s muscles, tendons, and bones
can lift or withstand, an absolute strength that cannot
be exceeded. The maximum an ordinary person can
lift, for example, using conscious effort (as in a gym)
is about two-thirds of his or her absolute strength,
but some professional athletes in intense competitions
have reached 92% of their body’s absolute strength.
Similar limits have been identified with tragic results in
extreme martial arts tests of invulnerability. In 2012,
students of pencak silat (an Indonesian form) died in the
course of progressively difficult tests of invulnerability
(Fointuna, 2012). A trio of men from one silat school
ingested rat poison, and when none sickened, they lay
down in the street while motorcyclists drove over their
bodies several times without causing injury. Then they
had a four-wheel vehicle loaded with passengers roll
over their bodies, which crushed and killed them. In
a separate incident the previous day, two other pencak
silat practitioners died from severe burns. They had
been testing their invulnerability to weapons and fire
but were unable to withstand being doused with an
unspecified acid. Reports of snake-bite fatalities among
Appalachian Christian snake handlers make headlines
with some frequency (e.g., Ball, 2015).
These few examples demonstrate the similarity
between apparently superhuman abilities to withstand
blades and fires demonstrated by berserks and the
spiritually-based invulnerability techniques from other
cultures that may be an unrecognized, universal human
capacity (c.f., Murphy, 1992; Kelley, 2007). The stories
of the berserks were not far-fetched, and if anything,
point to a significant gap in transpersonal and body-
mind studies.
Conclusion
Warrior-shamanism and dark magic are universal
phenomena in which becoming-intense and
becoming-animal are not only adaptive but also
productive of nonordinary states and transpersonal
identifications that take people out of their individual
concerns, rendering them willing to sacrifice personal
safety and even survival for a greater goal. Berserkergang
is a particular version of war magic, probably the best
documented of an ancient Indo-European ecstatic warrior
tradition celebrated in classic texts that remain influential
One of the Tunisian soldiers ... seized a sword and
began to lacerate his stomach. The blood flowed
freely, and he imitated all the time the cries and
movements of the camel. We soon had a wolf, a
bear, a hyena, a jackal, a leopard, and a lion.... A
large bottle was broken up and eagerly devoured....
Twenty different tortures were going on in twenty
different parts of the hall. (Littell & Littell, 1882,
p. 424).
According to Hall (2001, 2004, 2011), adepts
of the Sufi Tariqa Casnazaniyyah school, who pierce
their bodies with spikes, blades, glass, and the like, have
demonstrated such complete control over pain, bleeding,
and infection that their wounds heal within 4-10
seconds. Followers have been observed demonstrating
instantaneous healing of deliberately caused bodily
damage, such as jamming spikes and skewers into their
bodies, hammering daggers into their skulls and clavicles,
and chewing and swallowing glass and sharp razor blades.
Hall, trained in the practice himself, has reproduced it
reliably in laboratory conditions (2004, 2011; Hall,
Don, Hussein, White, & Hostoffer, 2001). He averred
that anyone could develop the capacity, as a transferable
ability (not the result of years of practice) “based on a
spiritual link…to the current Shaikh Master of the
Tariqa Casnazaniyyah Sufi School” (2004, p. 93), but
that the same phenomena have also been observed among
Brazilian trance surgeons. In such procedures, there was
“apparently no postoperative infection or pain, bleeding
is minimal” (Hall, 2004, p. 93). Based on EEG readings
of Sufi participants during the wounding process, Hall
claimed that these phenomena were not related to
“hypnosis, realization, altered states of consciousness, or
trance states such as relaxation or meditative states” (2004,
p. 93; 2001, 2011). However, the Sufi demonstrations
were a deliberate, planned activity; if adepts were wounded
accidentally, they did not experience rapid healing.

today, such as the Rig Veda and the Iliad. Part of the
largely unknown European pagan heritage, berserkergang
as a form of battle trance illustrates only a fraction
of the horizons war magic opens up for exploration,
especially transcendence through self-sacrifice, spiritual
trial by ordeal, different ways of understanding
transpersonal identification and existential meaning,
and supraphenomenal mind-body capabilities with an
emphasis on embodiment. Though part of a specific Indo-

religiously-inspired violence. Berserkergang can provide
insights for effective battlefield preparation and recovery.
