How is it possible to be a child again? Once you have tasted knowledge you cannot fall back. You can transcend it but you cannot go back, there is no way to go back. You can go ahead, you can go beyond it, but you cannot go behind it now; there is no way. You cannot be an ordinary child again. How? How can you lose that which you have known? But you can go beyond, you can transcend.
Remember this, otherwise you may start imitating a child and that imitation will be a cunningness, it will again be a calculation: because Jesus says, “Be like a child,” so you start practicing how to be like a child. But a child never practices. A child is simply a child, he doesn’t even know that he is a child, he is not aware of his innocence. His innocence is there, but he is not self-conscious about it. But if you practice then self-consciousness will be there. Then this childhood will be a false thing. You can act it but you cannot be a child again, in the literal sense.
A saint, a sage, becomes like a child in a totally different sense. He has transcended, he has gone beyond mind, because he has understood the futility of it. He has understood the whole nonsense of being a successful man in this world. He has renounced that desire to succeed, the desire to impress others; the desire to be the greatest, the most important; the desire to fulfill the ego. He has come to understand the absolute futility of it. The very understanding transcends: the very understanding and immediately you are transformed into a different dimension.
Then there is again a childhood; that is called the second childhood. Hindus have called that stage “the twice-born,” dwij. Again you are born, but it is a different birth, not out of a father and a mother. It is out of your own self, not out of two bodies meeting, not out of duality. It is through your self that you are born.
This is the meaning of Jesus’ birth: that he was born out of a virgin. But people take everything literally and then they miss. Out of the virgin means out of the one: there is no other, so who can corrupt it? Who can enter into it? The virginity remains absolutely pure because there is no other. When the other is there you have lost your virginity. If in the mind the other is there, you have lost innocence. So the consciousness of the other, the desire for the other, is losing virginity. This second birth can be virgin; the first birth is bound to be out of sex. There is no other way, there cannot be.
Jesus is born out of sex like anybody else, and it is right that it should be so. Jesus is just like you in the seed, but in the flowering he is absolutely different, because a second birth has happened; a new man is born. Jesus who was born out of Mary is no longer there, he has given birth to himself. In the old Essene sect it is said that when a man is transformed he becomes his own father. This is the meaning: when we say Jesus has no father, it means now Jesus has become his own father. This looks absurd but this is how it is.
