Visionary experience occupies a contested but central position across the depth-psychology corpus, traversing the boundary between clinical observation, mystical theology, and psychopharmacological research. Johnson grounds the term within a Jungian-mystical register, identifying it as an eruption of the medieval ‘unitive vision’ into consciousness — a momentary apprehension of the self’s underlying wholeness that operates on unconscious attitudes long after the event’s intensity has faded. Huxley approaches the same territory from a perceptual-philosophical angle, distinguishing visionary experience from mystical experience proper: the former remains within the realm of opposites, the latter transcends it — a distinction with significant soteriological consequences. Jung and his interpreters (von Franz, Corbin) press the phenomenon toward questions of ontological status and phenomenological legitimacy: are such experiences psychic events with genuine transformative force, or pathological intrusions? Corbin, reading through Iranian Sufism, theorizes a ‘visionary apperception’ that is irreducible and primary, demanding its own epistemology. The psychedelic researchers — Huxley, Grof, Strassman — contribute empirical and phenomenological taxonomies, mapping the content and neurological correlates of visionary states. Across the corpus, a persistent tension runs between the impulse to pathologize or reduce visionary experience and the equally strong impulse to honor it as a legitimate mode of knowing.
