According to Osho, yes—the theory of reincarnation is largely an interpretation layered on a common spiritual experience. Different traditions translate the same inner reality through their own lenses: Hindus and Jains affirm rebirth and a soul, Buddhists speak of continuity without a fixed soul, while Christians and Muslims reject reincarnation. Hence, doctrines vary; direct experience matters more than beliefs.
People may feel the same deep truth, but religions tell different stories about it—so look within and see for yourself.
