According to Osho, Christianity is not a philosophy but a theology based on belief and faith that forbids real questioning. He, instead, offers no philosophy or theology: he rejects both belief and doubt, proposing an experiential way—search, silence, watchfulness, meditation—until awareness turns back on itself (no-mind), which he calls enlightenment. Thus, dogma is replaced by direct personal consciousness.
Christianity says “believe”; Osho says “look within and experience truth yourself through meditation.”
