Celtic Shamanism: Vision Quests, Otherworld Travel, and Inner Druidry

By Thalira Wisdom | Updated March 2026

Defining Celtic Shamanism

The term "Celtic shamanism" requires immediate clarification of both components. "Shamanism" is a word derived from the Tungusic šaman, a specialist among the indigenous peoples of Siberia and Central Asia. Mircea Eliade, in Shamanism: Archaic Techniques of Ecstasy (1951), broadened the term to describe a cross-cultural complex of practices defined by: the practitioner's ability to enter controlled trance states, travel through multiple cosmological levels in spirit form, communicate with spiritual beings (ancestors, nature spirits, gods), and return to ordinary consciousness bearing knowledge or healing power for their community.

By Eliade's definition, the Celtic tradition contains clear shamanic elements. The question is not whether Celtic peoples had shamanic practices but what to call their practitioners. The relevant figures include: the Druid (the Gaulish, British, and Irish philosopher-priest trained in cosmology, law, and ritual); the filid (Old Irish: plural of fili, the seer-poet of the Irish aristocratic tradition); the awenyddion (Welsh: those inspired by the Awen, visionary seers); the ban fheasa (Irish: woman of knowledge, wise woman); and the ovate or vate (the prophetic class identified by Strabo and Diodorus alongside the bards and Druids).

John Matthews, in his foundational work The Celtic Shaman (1991), and Philip Carr-Gomm, through the OBOD Ovate grade curriculum, have done the most to articulate the shamanic dimensions of Celtic spirituality in accessible modern form. Both draw on the primary sources: the Irish mythological cycles, the Welsh Mabinogion, the classical accounts of Druidry, and the surviving Irish texts that describe specific trance and vision practices in unusual detail.

The Filid: Seers and Poet-Shamans

The filid (singular: fili) of ancient Ireland occupied a social position without direct modern equivalent. They were simultaneously poets, historians, legal experts, genealogists, and visionary seers. Their training lasted seven to twelve years (some sources say up to twenty). They memorised hundreds of stories, thousands of verse forms, the genealogies of the aristocratic families they served, and the mythological traditions of Ireland in their full complexity.

But the filid were not merely scholars. The highest grade, the ollam, was considered to possess imbas (inspired knowledge) that exceeded rational learning: a direct perception of truth that came through trained trance states, not through study alone. The ollam's praise could elevate a king's reputation and his satire could strip it: both because the ollam's words were understood to have real cosmological force, not just social influence. In Celtic understanding, the word shaped reality. The poet who could perceive the truth of things and speak it clearly was not making arguments; he was doing something closer to magic.

Kuno Meyer, who produced the first major scholarly editions of early Irish literature in the late 19th and early 20th centuries, and Proinsias Mac Cana, in The Learned Tales of Medieval Ireland (1980), document the social and intellectual world of the filid with scholarly rigour. Their picture of a class of specialists who held living tradition, served as community memory, and possessed trained access to visionary states of consciousness is one of the most complete portraits of a functioning shamanic intellectual class in any documented culture.

Imbas Forosnai: Illumination from Within

Imbas Forosnai (Old Irish: "illumination that encompasses" or "knowledge that illuminates") was one of the three primary visionary techniques of the Irish Druidic and filid tradition. The other two were Dichetal do Chennaib (spontaneous fingertip inspiration) and Teinm Laida (illumination by verse, a form of divinatory chanting). Of the three, Imbas Forosnai was the most elaborate and the most dangerous to practice, which is perhaps why it was the one specifically banned by Saint Patrick.

The ninth-century Irish text Cormac's Glossary describes the process: the practitioner chews raw flesh (typically pig, dog, or cat) while calling on the gods and asking for the revelation of what they seek to know. They then place their two palms on their cheeks and sing an incantation. Then they sleep. The answer comes in the sleep as a direct revelation. On waking, if the revelation has not come, the practice may be extended for up to nine days.

The sensory elements are significant from a neurological standpoint. The chewing of raw flesh (unusual and somewhat disturbing) creates a physiological disruption that activates the body's stress response and heightens alertness. The ritual darkness reduces external sensory input. The incantation (mantric in structure) induces rhythmic respiratory changes associated with trance. The sleep that follows is likely hypnagogic rather than ordinary sleep: the threshold state between waking and sleeping in which spontaneous imagery, symbolic experience, and genuine intuitive knowledge are more accessible than in either waking or deep sleep.

The fact that Saint Patrick specifically banned Imbas Forosnai confirms both its practice and its power. He would not have bothered banning a technique that did not work. His objection was theological: the practice called on pagan gods for revelation. This is precisely the form of evidence historians find most useful: external hostile testimony confirms the practice more reliably than sympathetic internal accounts.

Dichetal do Chennaib: Spontaneous Inspiration

Dichetal do Chennaib (Old Irish: "incantation from the fingertips" or "chanting from the ends") was the most spontaneous of the three filid visionary techniques. Where Imbas Forosnai required elaborate preparation and incubation, Dichetal do Chennaib was practiced in the moment: the seer touched a person or object and immediately received inspired knowledge about it.

The touching of fingertips to the subject, followed by immediate prophetic utterance without any preparation, parallels practices documented in multiple shamanic traditions involving direct bodily contact as a diagnostic and visionary tool. The practitioner's trained body becomes a receiver: the hands, held to a specific point of contact, transmit information that bypasses rational processing and comes directly as knowing.

Dichetal do Chennaib was the one technique Saint Patrick allowed to continue, because it did not require the explicit invocation of pagan gods. It could be recontextualised as a Christian charismatic gift rather than a pagan magical technique. This practical accommodation preserved the practice, even if in altered form, through the conversion period.

In modern Celtic shamanic practice, Dichetal do Chennaib is the model for intuitive divination: the trained practitioner's ability to receive direct knowledge through physical contact, attentive presence, or spontaneous insight without methodical calculation. It is the shamanic mode of knowing: immediate, embodied, pre-rational, and often more accurate than analytical reasoning about the same subject.

The Awenyddion: Welsh Prophetic Seers

One of the most remarkable pieces of evidence for Celtic shamanic practice comes from an unlikely source: Gerald of Wales, a Norman-Welsh cleric writing in 1188. In his Itinerarium Cambriae (Itinerary through Wales), Gerald describes a class of seers he personally observed called the awenyddion (singular: awenydd), meaning "those inspired by the Awen."

Gerald's account: when consulted about future events or important questions, the awenyddion fell into what appeared to be a trance or possession state. They roared and shook. They spoke in poetic, symbolic, and often oblique language that required interpretation. When they came out of the trance, they remembered nothing of what they had said. They could not repeat their visions on command. The inspiration came and went of its own accord.

This description matches the "possession" end of the shamanic spectrum (as opposed to the "controlled trance" model of the filid). The awenyddion did not ride the Awen; the Awen rode them. Their role was not to control the visionary state but to be sufficiently clear as vessels that accurate knowledge could pass through them. The interpretation required by their audience is also consistent with prophetic traditions across cultures: the vision arrives in symbolic and mythological language that a trained interpreter must translate into practical meaning.

Otherworld Journey in Celtic Practice

The Otherworld journey is the defining act of Celtic shamanism, as it is of shamanism generally. In the mythology, heroes travel to the Otherworld through burial mounds, across seas, under lakes, and through forest clearings where the veil between worlds thins. These narrative journeys are both literal mythological events and maps of inner experience.

The Immrama (voyage tales), the echtrai (adventure tales), and the hero tales of the Ulster and Fenian cycles all encode the structure of the Otherworld journey. The hero crosses a threshold (often involving water, a bridge, or a forest passage), encounters beings of increasing power and strangeness, receives knowledge or transformation, and returns (usually with difficulty) to the ordinary world. The return is typically as significant as the journey: the hero who cannot return has been swallowed by the Otherworld and is lost to the community.

In Druidic practice, the Otherworld journey is undertaken through trance states induced by drumming, chanting, breath practices, or extended sensory reduction. The practitioner sets a specific intention (to visit the lower world of nature spirits and ancestors, the middle world of the living landscape, or the upper world of cosmic intelligence), allows their consciousness to shift from ordinary waking awareness to the imaginal-visionary mode, and travels with purpose rather than passively drifting. The guidance of a trained teacher and the holding of the group (for group workings) provides safety: someone maintains the ordinary-world anchor while the journeyer travels.

Three Misconceptions About Celtic Shamanism

Power Animals and Shapeshifting

Across the Celtic mythological tradition, certain animals carry specific qualities of spiritual power and serve as intermediaries between the human world and the Otherworld. The salmon, the raven, the stag, the horse, the boar, the hare, the bear, and the crane all appear consistently as significant spiritual beings rather than mere fauna.

The salmon of the pool of Connla holds all wisdom (its story is discussed below). The raven is the omen-bird of the Morrigan, appearing before death or transformation. The stag is the animal of Cernunnos, the lord of wild things, and signals the presence of the deep wildness of nature that exceeds the human order. The white horse is the mount of sovereignty: in the Irish kingship inaugurations, the king symbolically mated with a horse representing the land itself. The boar appears repeatedly as an animal of terrible power that heroes must overcome to prove themselves.

Shapeshifting, the practitioner's ability to assume animal form in spirit or in actuality, appears throughout the Celtic tradition as a marker of shamanic ability. Taliesin's account of his transformations in Hanes Taliesin (a hare, a fish, a bird, a grain of wheat, a hen who swallows the grain) maps a classic shamanic initiatory death-and-rebirth sequence. Cú Chulainn's riastrad (warp-spasm) in the Ulster Cycle is a form of animal possession: he temporarily becomes something non-human, beyond human control, channelling a power that exceeds his ordinary self.

In modern Celtic shamanic practice, working with a power animal involves entering the Otherworld in a specific Lower World journey and encountering the animal that presents itself as a companion and teacher. The practice is not decorative: a power animal relationship provides a specific mode of perception and action that the practitioner's human consciousness alone cannot access. The stag gives the quality of the forest's patience. The salmon gives the quality of deep knowledge. The raven gives the ability to see between worlds.

The Salmon of Wisdom

The Salmon of Knowledge (Old Irish: Bradán Feasa) is one of the most important shamanic symbols in the entire Celtic tradition. It lives in the pool of Connla, where nine hazel trees surround the water. The hazels drop their nuts into the pool. Each nut contains all knowledge: poetry, wisdom, and the memory of all things that have ever happened. The salmon eats the nuts as they fall and becomes the repository of all wisdom in the world.

The poet-seer Finnegas has spent seven years by the pool, waiting to catch and eat this fish, believing that according to a prophecy he will be the one to do so. When the salmon is finally caught, the young Fionn mac Cumhaill is given it to cook. He burns his thumb while turning it, instinctively puts his thumb to his lips, and in that moment receives the salmon's wisdom. He does not receive all knowledge permanently: he receives access to it through the technique of putting his thumb to his lips (an act that corresponds to Imbas Forosnai's emphasis on the hands and the mouth as the sites of visionary transmission).

The symbolism is precise and consistent with Celtic shamanic cosmology. The hazel is the tree of wisdom and inspiration. The pool represents the unconscious depths from which wisdom arises. The fish is the wisdom itself, moving through those depths. The accidental burning of the thumb, the spontaneous placing of the lip: this is the Dichetal do Chennaib model, inspiration arriving without preparation, through the direct physical contact of the inspired seeker. Fionn's entire subsequent career as the greatest seer and warrior in Irish tradition flows from this moment of accidental grace.

The Awen: Celtic Shamanism's Central Force

All Celtic shamanic practice ultimately centres on the concept of Awen (Welsh and Irish: "flowing spirit," "divine inspiration," "the divine current"). The Awen is not a personal possession but a cosmological force: the flow of divine intelligence through creation that, when a practitioner aligns with it, produces poetry, prophecy, healing, and wisdom.

The Awen cannot be manufactured through technique. What technique does is create the conditions in which the Awen can flow: by clearing the practitioner's inner obstructions (fear, ego-attachment, distraction), by aligning consciousness with the natural rhythms of the world (seasonal observation, time in nature, ritual), and by developing the specific receptive quality that allows the force to pass through rather than be stopped by the practitioner's personality.

This is precisely the distinction Carr-Gomm makes between the Bardic level (learning to be open to inspiration) and the Ovate and Druid levels (developing the capacity to work with what the inspiration reveals). The Awen flows freely at the Bardic level through creative practice. At the Ovate level, it becomes the engine of the Otherworld journey. At the Druid level, it is the source of the wisdom that allows the philosopher to see the pattern of reality and act within it with clarity.

The Druidic Training as Shamanic Initiation

The ancient Druidic training of up to twenty years was not merely an education in facts. It was a systematic initiation into shamanic consciousness. Caesar's observation that the Druids memorised vast amounts of material rather than writing it down is not evidence of technological limitation but of deliberate methodology: oral transmission requires the total engagement of memory, imagination, and body in a way that written transmission does not. The material is inscribed not just in the mind but in the whole organism.

The training included what modern scholars recognise as shamanic initiation elements: extended periods in nature, fasting, sleep deprivation (the dark-house practices associated with Imbas Forosnai), ritual immersion in water, the cultivation of specific trance techniques, and the gradual assumption of responsibility for holding and transmitting the tradition. The Druidic initiation was not a one-time event but a decades-long transformation of the entire being.

The physical ordeals documented in the Irish initiatory tradition (the warrior initiations of the Fianna involving running through a forest while being hunted, composing verse while being speared from nine directions, standing neck-deep in water) are shamanic initiation tests: they push the practitioner beyond their ordinary capacities and force the emergence of something beyond the personal self. What emerges from these tests is not technique but presence: the quality of being that allows the practitioner to function in the Otherworld as effectively as they do in the ordinary world.

Modern Celtic Shamanic Practice

Contemporary Celtic shamanism draws on both the ancient sources (the Irish mythological cycles, the Welsh Mabinogion, the classical accounts of Druidry) and the modern revival initiated by figures including Caitlin and John Matthews, Philip Carr-Gomm, Danu Forest, and John Michael Greer. The OBOD Ovate grade curriculum remains the most systematic introduction to Celtic shamanic practice available, covering Otherworld journeys, ancestor communication, power animal work, and the cultivation of the inner senses.

Practical Celtic shamanic work today typically involves: daily time in nature with the quality of attention the tradition calls "Ovate awareness" (listening rather than looking, feeling rather than thinking); seasonal rituals aligned with the Celtic festival cycle; Otherworld journeys using drumming, chanting, or breath practices as trance induction; work with specific deities and nature spirits from the Celtic tradition; and the cultivation of the Awen through creative practice, dream work, and contemplative inquiry.

What distinguishes authentic Celtic shamanic practice from casual mythology consumption is commitment to the specific cosmological framework of the Celtic tradition. The Otherworld is not any old imagination; it is a specific cosmological reality with consistent features documented across the Irish and Welsh sources. The Tuatha De Danann are not generic "light beings"; they are specific personalities with specific domains and specific ways of working. The practitioner who engages with the tradition as a living system, rather than a collection of colourful images, accesses something qualitatively different from the practitioner who merely borrows its aesthetic.

The Hermetic Connection

Celtic shamanism and the Hermetic tradition converge on a common cosmological insight: reality has multiple dimensions, the human being has the capacity to perceive and act within all of them, and the development of that capacity is the highest purpose of human life. The Hermetic practitioner's work with the planetary spheres and the Druidic Ovate's Otherworld journey are different cultural maps of the same inner geography.

Hermes Trismegistus embodies the same archetype as the ollam of the filid: the figure who holds philosophy, prophecy, and sacred knowledge in a single integrated vision, who has descended into the depths of reality and returned with the full account. The Corpus Hermeticum's description of the soul's ascent through the planetary spheres is structurally identical to the Celtic hero's Otherworld journey through multiple islands, each with a different quality of reality. Both are maps of consciousness discovering its own dimensions.

The most direct convergence is in the concept of divine inspiration itself. The Hermetic Nous (divine Mind) that illuminates the practitioner who has sufficiently emptied themselves of ego-attachments is functionally identical to the Awen that flows through the practitioner who has become a sufficiently clear channel. Both traditions agree that the deepest knowledge is not manufactured by intellect but received by a consciousness that has learned to be still enough to allow the deeper current to flow through it.

The Hermetic Synthesis course at Thalira develops exactly this territory: the cultivation of the inner receptivity that makes genuine contact with the deeper dimensions of reality possible. Celtic shamanism offers one of the most practically grounded paths to this cultivation, because it is rooted in the natural world and in the specific practices of a tradition that was refined over centuries of direct experience. You do not need to become Irish or Welsh to benefit from this tradition. You need to learn to listen.
