Buddhists believe that the body is made of four elements, states Osho.
And the fifth is your consciousness, which is not part of the body but lives in the body; which can go out, can enter into another womb. This fifth is your reality. In your deep silence you start disentangling yourself from the body, from the mind, from the heart. And what remains is just a pure space.
This pure space is the origin of you and of all. This pure space has never changed, it is always here and now. It knows no time, no space. It fills the whole universe, which is infinite. Once you have known it, your life changes.
Remember, it should not only be a view. If you experience such a space, you will then be free to go or stay. Once you have known this space you have known freedom. And then it is up to you to remain in your form, to change the form, or simply to disappear into the infinity of existence.
As far as I know, nobody who has known this space has ever entered into another form. The enlightened man’s life is his last life. Why should he bother to get into another headache? Why should he get into another imprisonment, which has illness, sickness, oldness, death and thousands of miseries?
It is only the unconscious human being who goes on groping from womb to womb. The conscious one simply leaves this body and becomes part of the sky. There is no need to be confined unless you love to torture yourself. Nobody has done that up to now. Perhaps nobody can do it. Seeing the freedom of infinity, who is going to look back towards a form, a body, with all its suffering, misery, troubles? It is just against nature.
