vii. 20 (xxxiv. 2). Then comes the begging of a place of sacrifice. They say 'Seeing that a Brahman, a Rājanya, a Vaiçya, when about to consecrate himself asks a Kṣatriya for a place of sacrifice, whom is the Kṣatriya to ask?' 'He should ask the divine lordly power' they say. The divine lordly power is the sun; the sun is the overlord of these beings. On the day on which he is going to consecrate himself, on that day in the forenoon he should revere the rising sun; with

'This is the best of lights, the highest light.'

With 'O god Savitṛ, give me a place of sacrifice for sacrifice to the gods' he asks for a place of sacrifice. In that being asked here he goes on his upward course, 'Yes, I give it' he says in effect. No harm befalls him instigated by the god Savitṛ; ever increasing prosperity he attains; he attains lordship over offspring and supremacy, who having thus paid reverence, having asked for, having settled on a place of sacrifice, consecrates himself, being a Kṣatriya.
