According to Osho, reincarnation is the continuity of one’s unfulfilled desires and karmic tendencies, not the travel of a fixed ego. Body dies; the mind-stream, driven by desire, seeks new forms—moment to moment and between lives. Through awareness and meditation, desires dissolve, the witness is realized, and the wheel of birth and death ceases; then there is freedom.
It’s like your habits and wants jumping to a new body until you wake up inside and stop the jumping.
