Everybody sacrifices, even the beasts erect altars and fires![24] That one should sacrifice without the ulterior motive of gain is unknown.

Brahmanic India knows no thank-offering.

Ordinarily the gain is represented as a compensating gift from the divinity, whom the sacrificer pleases with his sacrifice.

Very plainly is this expressed.

"He offers the sacrifice to the god with this text: 'Do thou give to me (and) I (will) give to thee; do thou bestow on me (and) I (will) bestow on thee'" (_V[=a]j.
