YV 5.7l

Again the fire which is piled up is cruel, and if one were not to cast upon the fire which has been piled up these oblations, the cruel fire would spring up in wrath, and injure the offspring and cattle of the sacrificer. In that he casts the oblations on the fire which has been piled up, he appeases it with its own portion, and the cruel fire [1] does not spring up in wrath and injure his offspring and cattle. There are ten oblations. Nine are the breaths in man, and the navel is the tenth; verily he places breaths in the sacrificer. Again the Viraj is of ten syllables; the Viraj is food; verily he finds support in the Viraj as food. 'It must be piled with the seasons, the metres, the Stomas, and the Prsthas', they say. In that he casts these oblations, he piles it with the seasons, the metres, the Stomas, and the Prsthas. 'The quarters can be won by one who has pressed the Soma' they say [2]. In that he casts these oblations, (it is) for the winning of the quarters. The gods made Indra sacrifice with it, and therefore is it Indra's pressing; men made Manu sacrifice with it, and therefore is it Manu's pressing. As Indra among the gods, as Manu among men, becomes he who knowing thus sacrifices with this sacrifice. The Puronuvakyas contain the word 'quarter', for the conquest of the quarters. vii. 6. 16. a Who is the sole lord of the world, Which breatheth and winketh, through his greatness, Who is the lord of biped and of quadruped here, Who is the god whom we are to worship with oblation? b Thou art taken with a foundation. I take thee dear to Prajapati. Of thee the sky is the greatness, the Naksatras the form, the sun the splendour; to his greatness, to Prajapati, thee (I offer). Hail! vii. 5. 17. a He who is the giver of soul, the giver of strength, On whose instruction all, on whose (instruction) the gods depend. Whose shadow is immortality, whose shadow is death; Who is the god whom we are to worship with oblation? b Thou art taken with a foundation.
