Hades' realm is contiguous with life, touching it at all points, just below it, its shadow brother giving to life its depth and its psyche. Because his realm was conceived as the final end of each soul, Hades is the final cause, the purpose, the very telos of every soul and every soul process.
Hillman establishes Hadean consciousness as the teleological ground of all psychic life, a coextensive underworld perspective that gives depth to every soul process rather than standing as a remote afterlife.
