According to Osho, when a person returns as a human being, it is the astral mind’s unfinished desires that pull it back into a human body. At death—like deep sleep—whatever couldn’t be completed stands present, and upon re-entry those cravings seek conditions to fulfill themselves, shaping the new life’s initial impulses, tendencies, and circumstances.
Your leftover wishes chase you back into a human body so you can try to finish them.
