I am suggesting that, for Kazantzakis, it is God who is "Immortal." What this means is that Kazantzakis is searching neither for heaven nor Nirvana nor ataraxia.This negativity is not absolute, but rather indicative of the psychic renewal consistent with Buddhism and Christianity (including Greek Orthodoxy). It is a "rest in the life force's evolution toward ever-increasing value."
