According to Osho, Buddhahood means awakened consciousness: the breaking of spiritual sleep and intoxication (ego, wealth, status) so one stands up and walks home to one’s source. It is not a person or role but formless awareness beyond all identities and states. Anyone asleep can awaken; a little conscious effort suffices.
It’s like waking from a long, drunken dream, remembering your real self, and starting the journey home inside.
