YV 1.3e

In that he prepares (them) with these two (verses), verily by addressing him with them he secures him, so that his self is not injured. He prepares (them) with two; the sacrificer has two feet; (verily it serves) for support. Having prepared them, he offers five libations; cattle are fivefold; I verily he wins cattle. Now the victim is led to death, and if he should lay hold on it, the sacrificer would be likely to die. ' The breath of the sacrifice is apart from the victim', he says, for distinction [1]. 'If the victim has uttered a cry'--(with these words) he offers a libation, for calming. 'O ye slayers, come to the sacrifices', he says; that is according to the text. When the omentum. is being taken, the strength goes away from Agni. 'Thee they keep to carry the offering'--(with these words) he pours a libation over the omentum; verily he wins the strength of Agni; (it serves) also for making (the victim) ready. In the case of some gods the cry of 'hail!' is uttered before (an offering), in the case of others the cry of 'hail!' is uttered after. 'Hail to the gods, to the gods hail!'--(with these words) he pours a libation on either side of the omentum; verily he delights both (sets of gods). a 'He who performs the sacrifice not according to the deities falls a victim to the deities, he becomes worse. He who (performs) in accordance with the deities does not fall a victim to the deities, he becomes better. He should rub the Agnidh's place with a verse addressed to Agni, the oblation-holder with one addressed to Visnu, the offering-spoons with one addressed to Agni, the Vayu cups with one addressed to Vayu, the Sadas with one addressed to Indra. Thus he forms the sacrifice in accordance with the deities, he does not fall a victim to the deities, he becomes better. b I yoke earth for thee with light, I yoke wind for thee with the atmosphere [1], I yoke speech for thee with the sun, I yoke the three spaces of the sun for thee.
