Rebirth stands among the most densely theorized concepts in the depth-psychological corpus, drawing together archetypal psychology, transpersonal research, comparative religion, and evolutionary metaphysics into a field of sustained interpretive tension. Jung provides the architectonic foundation, taxonomizing rebirth into five phenomenological forms — metempsychosis, reincarnation, resurrection, renovation, and participation in a transformation process — and anchoring all of them in the archetype as the primordial affirmation underlying cross-cultural concurrence. Eliade approaches the term from the history of religions, demonstrating that water symbolism, initiatory death, and cosmogonic repetition structurally encode a regenerative logic operative from Brahmanic sacrifice to Christian baptism. Stanislav Grof relocates rebirth experientially, mapping the death-rebirth sequence onto perinatal matrices accessed through psychedelic and holotropic states, insisting on its empirical reality within the therapeutic encounter. Aurobindo integrates rebirth into a philosophical cosmology of evolutionary ascent, arguing that the rational necessity of soul-continuity underwrites each successive embodiment. Harrison, Vernant, and Neumann supply the mythological and archetypal groundwork — Pythagorean palingenesia, eschatological Mnemosyne, and the Terrible Mother’s womb as vessel of return. Campbell reads rebirth as the universal formula underlying heroic mythology worldwide. The central tension in the corpus is ontological: whether rebirth names a literal metaphysical fact, an archetypal psychic structure, or a symbolic grammar for psychological transformation.
