Osho – The last statement of Gautama the Buddha to his disciples was: Be a light unto yourself. They were crying and weeping, naturally — the master was leaving and they had lived with the master for almost forty years; a few older disciples had lived with him the whole time. These forty years were of tremendous joy, of great experiences. These forty years had been the most beautiful time possible, humanly possible. These forty years had been days of paradise on earth. And now the master is leaving! It was natural, they started crying and weeping.
Buddha opened his eyes and said, “Stop crying and weeping! Have you not listened to me yet? Why are you crying?”
His chief disciple, Ananda, said, “Because you are leaving, because our light is leaving. We see, we feel darkness descending upon us. I have not yet become enlightened and you are leaving. If I could not become enlightened while you were alive, what is the hope for me now when you will be gone? I am in great despair, my anguish is incalculable, I have wasted these forty years. I have been following you like a shadow, it was tremendously beautiful to be with you, but now you are leaving. What is going to happen to us?”
Buddha said, “You are crying because you have not heard me yet. I have been telling you again and again: Don’t believe in me — but you have not listened. Because you have believed in me, and now I am dying, your whole structure is falling apart. Had you listened to me, had you created a light into your being rather than becoming knowledgeable through me, if you had experienced your own self there would have been no need to cry.
“Look at Manjushree!” he said — Manjushree was another disciple of Buddha, one of the greatest. He was sitting under a tree just close by, with closed eyes, so serene, so quiet, so utterly blissful, that Buddha said, “Look at Manjushree! Go and ask him why he is not crying.”
They asked Manjushree. He laughed and said, “What reason is there to cry? Buddha has helped me to know my own light. I am thankful, I am grateful, but there is no darkness descending. And how can Buddha die? I know I cannot die — how can Buddha die? He will be here. Just as a river disappears in the ocean he will disappear into the cosmos. But he will be here! He will be spread all over the cosmos. It is going to be something tremendously beautiful. Buddha was confined to a small body; now his fragrance will be released, he will permeate the whole of existence. I am tremendously happy that now Buddha will be spread all over space. I will be able to see him rising in the sun and I will be able to see him flying in a bird and I will be able to see him in the waves of the ocean… and I will be able to see him everywhere.
“He is simply leaving his body. It was a confinement. And how do I know it? I know it because I have known my own soul. I listened to him and you have not listened to him — that’s why you are crying.”
Buddha said, “Let me repeat again: APPA DIPO BHAVA — be a light unto yourself.” Then he closed his eyes and disappeared into the cosmos. But his last statement was also his first statement. In fact that was his whole message — the whole of his life he was repeating the same message again and again and again.
