According to Osho, you need not believe in reincarnation at all—drop the concern and live this very life totally. He urges inquiry over belief: become meditative, alert, and experiential rather than accepting others’ claims. By living consciously, doors open to see for yourself—past, future, or not. Until then, keep doubting and exploring; only firsthand experience has value, not borrowed belief.
Don’t believe or disbelieve—just live fully and meditate until you see for yourself.
