Jaiminīya (Talavakāra) Brāhmaṇa 2-7.261

'Vauṣaṭ!'—this is what we saw." He knew: "They have indeed seen it!" Because they were five, the sacrifice is fivefold. By that he knew: "They have indeed seen it!" And because of those being five, there were seventeen syllables; Prajāpati is seventeenfold, the sacrifice belongs to Prajāpati. By that too he knew: "They have indeed seen it!" He said: "With what will you make offering? In what will you make offering?" They said: "Having extracted your own omentum, we will offer it as a complete oblation into the fire in your own heart." They extracted Prajāpati's own omentum. Of them, breath called for recitation, and downward breath responded. Mind was the Hotṛ. Prajāpati himself, as the fourth, sat as the Brahman on the south. They offered it as a complete oblation into the fire in Prajāpati's own heart. That they scattered it, that is the omentum-nature of the omentum. That they offered it then, that was their scattering of it. Therefore, indeed, sowing must be done. For from what is sown, all this is born. From that [omentum] offered, a goat—

—white, shaggy, hornless, with dewlaps, having teeth on one side, four-footed, was born.

In it they saw all forms.

They said: "All these forms, indeed, are in it.

Come, let us seize this very one!"

They seized it.
