The House of Hades is a psychological realm now, not an eschatological realm later… 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’s central claim: Hades functions not as a post-mortem destination but as the immanent teleological ground of all psychic life, operative simultaneously with ordinary waking existence.
