The first is conception: the seed, the strength gathered from all the limbs, is placed in the woman, and she nourishes the child as her own self; the father, caring for the child before and after birth, cares for himself. The second birth is when the child is born, and the son takes the father's place in holy works. The third is when the father, his work done and old age come, departs and is born again. The rishi Vamadeva declared while still in the womb that he had known the births of all the devas, and broke out like a hawk from a hundred iron walls. Knowing this, he rose from the body, gained all desires in the world above, and became immortal.
First, the embryo arises in the man as seed. This seed is the vigour gathered from all his limbs; he carries himself within himself. When he places it in the woman, he gives it birth. That is his first birth.
She who nourishes should herself be cared for. The woman carries the child in her womb. The father cares for the child from its birth onward, and in caring for the child he cares for himself, for the continuance of these worlds; so these worlds go on. That is his second birth.
This self of his, the son, is set in his place to carry on the holy works. Then the father's other self, his duties done and his years complete, departs. Departing from here, he is born again. That is his third birth.
So the rishi said: while still in the womb I knew all the births of these devas. A hundred iron fortresses held me, yet like a hawk I broke out swiftly. Vamadeva spoke thus while yet lying in the womb.
