YV 6.3d

The oblation is a bolt, the portions of the oblation are a bolt [4], the Vasat call is a bolt; thus forges be a threefold bolt and hurls it at his foe, so as not to make a failure. He utters the Vasat call in anger, to lay low his foe. The Puronuvakya is the Gayatri, the Yajya the Tristubh; verily he makes the ruling class dependent on the priestly class; therefore the Brahman is the chief. The chief he becomes who knows thus. He proclaims him with the Puronuvakya, leads him forward with the Yajya, and makes him go with the Vasat call. He takes him with the Puronuvakya, he gives him with the Yajya, and [5] establishes him with the Vasat call. The Puronuvakya has three feet; these worlds are three; verily he finds support in these worlds. The Yajya has four feet; verily he wins four footed cattle. The Vasat call has two syllables, the sacrificer has two feet; verily afterwards he finds support in cattle. The Puronuvakya is the Gayatri, the Yajya, the Tristubh, and this is the sevenfooted Çakvari. Whatever the gods were fain to do by it, that they were able to do; he who knows thus can do whatever he is fain to do. Prajapati assigned the sacrifices to the gods. He placed in himself the oblation. The gods said to him, 'The oblation is the sacrifice; let us have a share in it.' He said, 'Lot them offer to you the portions of the oblation, let them pour out (a layer), let them sprinkle (it).' Therefore they offer the portions of the oblation, they pour out (a layer), and sprinkle (it). The theologians say, 'For what reason are the other offerings worn out, but the oblation fresh?' He should reply, 'Because it is Prajapati's [1], for Prajapati is of the gods the fresh one.' The metres ran away from the gods (saying), 'We will not bear the offering, if we have no share.' They kept for them (the offering) divided into four parts, for the Puronuvakya, the Yajya, the deity, the Vasat call.
