Once your understanding has become perfect about what death is and what life is…OSHO
Soul never dies, body is never alive. With the soul-body together, the body reflects the life of the soul. It is simply luminous with the life of the soul. The life is borrowed; it is like the moon. The moon has no rays of its own, it reflects the sun. The rays come from the sun, are reflected from the moon, but you see them as if they are coming from the moon.
It is as if you burn a small lamp in a room and somebody passing outside looks inside through the glass window. The glass window spreads the light of the lamp outside also, but the light is not coming from the glass window, it is coming from an interior place.
Your body reflects life — your body is luminous with the life of the soul. That's why when the soul disappears the body is dead. The body was always dead. Go and put off the light inside the room and the window will be dark. It was always dark because it has no light of its own.
Body is the stream of death, and if you continue to be attached to the body, you will again and again be falling into the stream of death. You will be born and you will be dying, and you will be born and you will be dying — this is what the Hindus call 'the wheel of life and death'. Go in, withinwards, and find the source of life. It is totally different from the body.
It has made its abode in the body, but it is not the body. That is the stream of life. Watching, gazing, witnessing these two…THE STREAM OF LIFE AND DEATH, THEY SEEK INTEGRITY.
And once your understanding has become perfect about what death is and what life is, you become integrated, you become centered. Because then no more is your center in the body. Then there is no longer any illusion that you are in the body. Then you are suddenly aware of the real center of your being, of your innermost shrine.
