According to Osho, upon attaining the fifth body one is awakened and no longer needs the first four bodies, so there is no return as human, deva, or preta. From the fifth you can function without form; a wholly new birth begins—an entry into the sixth plane of consciousness, beyond ordinary reincarnation.
After the fifth level, you don’t come back as a person or spirit; you begin a new, higher birth beyond the old bodies.
