YV 7.2e

When the Hotr utters the name of the sacrificer, then he should say, 'Hither these blessings have come, fain for milking'; verily he milks the deities which he praises together; verily he milks the sacrifice on both sides, in front and behind. 'With the red steed may Agni convey thee to the god', he says; these are the steeds of the gods [3], the straw is the sacrificer; in that he casts forward the straw with them, he makes the sacrificers to go by the steeds of the gods to the world of heaven. 'I unyoke thy head ropes, thy reins', he says; that is the unyoking of Agni; verily thereby he unyokes him. 'By sacrifice to the god Visnu, by the sacrifice may I attain health and wealth and security', he says; Visnu is the sacrifice; verily the sacrifice finds support at the end. 'By sacrifice to the god Soma, possessing good seed [4], may I impregnate seed', he says; Soma is the impregnator of seed; verily he confers seed upon himself. 'By sacrifice to the god Tvastr, may I prosper the form of cattle'; Tvastr is the form-maker of the pairings of cattle, and thereby he confers upon himself the form of cattle. 'The wives of the gods, Agni, the lord of the house, are the pair of the sacrifice; by sacrifice to these deities may I be propagated with a pair.' 'Thou art the bundle, thou art gain, may I gain', he says; by the bundle (vedena) the gods won (avindanta) the desirable wealth of the Asuras, and that is why the bundle has its name. Whatever of his foe's he may covet, the name of that he should utter; verily he wing it all from him. 'May the bundle bestow increase of wealth, rich in ghee, rich in houses, a thousandfold, strong', he says; he obtains a thousand cattle. In his offspring a strong one is born who knows thus. Through the emptying of the Dhruva the sacrifice is emptied, through the sacrifice the sacrificer, through the sacrificer offspring.
