The vagina as a psychological term traverses several distinct registers within the depth-psychology corpus. In classical Freudian formulations, it enters principally through developmental theory: the boy discovers it and is horrified, precipitating the castration complex; the girl, denied a visible penis, negotiates her libidinal economy through clitoris, envy, and eventual vaginal orientation. Rank extends the clinical picture by reading penetration of the vaginal opening as a partial symbolic return to the womb, forging the connection between genital sexuality and the primal uterine state. Campbell, drawing on ethnographic material and Jungian archetypal theory, maps the vagina onto the mythological ‘toothed vagina’ — a power-image generated not from outer nature but from the nervous structure itself, released as a sign stimulus of considerable psychic force. Neumann situates female genitalia within the Great Mother’s transformative symbolism: the cleft, the fissure, the gateway between life and death. Bleuler documents how schizophrenic symbolic systems substitute mouth for vagina, registering the oral-genital conflation that psychoanalytic theory tracked from the outset. Estés recovers the vulvar imagery of the Baubo goddess tradition as a locus of sacred-sensual autonomy belonging to the body rather than the intellect. Across these accounts a persistent tension organises the field: whether the vagina signifies lack, danger, and castration anxiety (the Freudian axis) or threshold, transformation, and generative mystery (the archetypal-mythological axis).
