Sama Veda II.7.1.3: They have drained forth from out the great

1. They have drained forth from out the great depth of the sky the old divine primeval milk that claims the laud:
They lifted up their voice to Indra at his birth.

2. Then, beautifully radiant, certain heavenly ones proclaimed their kinship with him as they looked thereon:
Savitar opens, as it were, the fold of heaven.

3. And now that thou, O Pavamana, art above this earth and heaven and all existence in thy might,
Thou shinest like a bull supreme among the herd.
