The ‘Primordial Condition’ names, across the depth-psychology corpus, that originary state of undifferentiated wholeness which precedes and undergirds all subsequent differentiation — whether psychological, cosmological, or ontological. Jung treats it as the living ground from which consciousness emerges: the union of opposites before conflict has arisen, symbolized by the hermaphrodite, the uroboros, and the Tao. In his reading, this condition is not merely a historical or evolutionary antecedent but a perpetually available psychic stratum — one that consciousness can descend into or ascend from at moments of transformation. Neumann extends this into a developmental schema, locating the primordial condition within uroboric consciousness, where body and psyche remain undivided. Eliade approaches it through the mythic and ritual repetition of origins, the illo tempore recovered in sacred practice. The Taoist tradition, represented here by Liu I-ming, frames it as the xiantian state — ‘before Heaven’ — from which temporal conditioning diverges and to which alchemical cultivation seeks return. What unites these voices is the conviction that the primordial condition is not archaic residue but an active structural fact, simultaneously the most regressed and the most ideal, the foundation of individuation as well as its perpetual gravitational undertow.
