Seidr (High Seat)

Identification

Seiðr names the divinatory and magical practice at the center of Norse shamanism, in which a völva (seeress) entered trance from a raised platform (seiðhjallr) to prophesy and communicate with spirits. Mythologically, the goddess Freyja is credited with bringing seiðr to the Æsir, teaching it to Odin himself. The practice's roots reach into the Iron Age, with its documented flowering during the Viking Age (roughly 793–1066); Eiríks saga rauða and the Poetic Edda's Völuspá remain central primary sources, alongside Snorri Sturluson's Edda.

Context

Performed at communal gatherings, feasts, and war councils, with a traveling völva invited into a settlement specifically to prophesy. Access was restricted to trained völvur, predominantly women; men who practiced seiðr (seiðmenn) faced social stigma associated with unmanliness (ergi). Prerequisites included lengthy training, possession of a ritual staff (seiðstafr), and knowledge of the varðlokur, the chants central to the rite. The traditional aim spanned prophecy, communication with the dead, weather and luck manipulation, healing, and cursing. In mechanical terms, the ritual induces a controlled altered state of consciousness through a combination of acoustic pressure and social-spatial isolation, suppressing analytical thought and surfacing associative, intuitive material that is then voiced and interpreted as vision.

How the tradition explains it

Singing the varðlokur draws helper spirits — nature spirits, ancestral dead — who show the völva what is hidden. The high seat lifts the seeress closer to Yggdrasil, the World Tree, letting her see further than ordinary sight allows.

What the science says

A continuous, monotonous, rhythmic vocal drone is a well-documented driver of frequency-following response, in which brainwave activity entrains to the frequency of an external rhythmic stimulus, shifting from beta (ordinary waking) toward theta (4–8 Hz) and, in some reports, gamma activity — theta specifically is associated with hypnagogic states and a loosening of ordinary associative censorship. Physical elevation on the platform functions as a form of social separation from the group, plausibly easing dissociation by reducing the pressure of ordinary social context. Combining sound overload — the chant enveloping the seer from every direction — with visual deprivation (closed eyes or a covering veil) creates conflicting input at the level of the reticular formation, a documented pathway toward dissociative states. The underlying principle is best understood as suppressing analytical, critical filtering long enough to let associative and intuitive processes generate imagery and narrative on their own, material the tradition then interprets as vision.

The classical völva ritual, described above, used a raised platform and a full choral chant. A solitary Odinic form, self-induced through isolation, hunger, and pain — echoed in the myth of Odin hanging on Yggdrasil — dispensed with the group entirely. Modern reconstructionist practice ("oracular seiðr," associated with Diana Paxson) adapts the ritual as a group ceremony using drums and chanting for a contemporary audience.

Traditional sources describe the risk of spirit possession, becoming "stuck" in the trance state, and severe psychic exhaustion. From the science: dissociative episodes in predisposed individuals, the potential provocation of psychotic episodes in those with schizophrenia, seizures triggered by monotonous rhythmic stimulation in people with epilepsy, and depersonalization or derealization are all documented risks. The practice is contraindicated for schizophrenia, epilepsy, dissociative identity disorder, PTSD with marked dissociation, and bipolar disorder during a manic episode.

Correct execution produces a felt lightness and "dissolving" of the body, spontaneous vivid visual imagery with the eyes closed, a loss of the sense of elapsed time, emotional neutrality, and a sense of observing from outside oneself. Escalating anxiety, headache, nausea, a panicked sense of losing control, and an inability to return to ordinary awareness all mark the practice going wrong.
