According to Osho, satchidanandghan Paramatma is the inner, changeless center of consciousness—the witness from which seeing and hearing happen—whose nature is sat (eternal being that never changes), chit (unbroken awareness untouched by bodily states), and ananda (intrinsic bliss). It is the base before birth and after death, the still presence amid all passing phenomena.
It’s the unchanging real you inside that is always awake and peaceful, even while your body and thoughts keep changing.
