Osho: I hope there will be a day when the whole humanity will understand this buddhahood. Spread this experience to all those who are groping in darkness. But never be a missionary; just be a message ... loving, compassionate. Let your whole body, your actions, make them aware that something immensely valuable has happened within you; that you are carrying a flame, that you are carrying a fragrance, that your eyes have become as blue and as vast and as deep as the sky itself. This I call "to be a message." Except becoming a buddha, there is no way to convey what you are experiencing. And remember: once a buddha, forever a buddha.
