YV 5.5d

' They gave it to the Rudras; they bore it for six days, thereby they created three hundred, three and thirty; therefore should it be borne for six days; verily is he propagated. To them the Adityas said, 'Ye have been propagated; let us [6] be propagated'. They gave it to the Adityas, they bore it for twelve days, thereby they created three hundred, three and thirty; therefore should it be borne for twelve days; verily is he propagated. Thereby they created a thousand, the pan being the thousandth; he who knows thus the pan as the thousandth obtains a thousand cattle. 'With a Yajus it is made, with a Yajus it is cooked, with a Yajus it is set loose, this pan; it is therefore exhausted, it cannot be used again', they say. 'O Agni, yoke thy (steeds)', 'Yoke them that best invoke the gods', (with these words) he offers in the pan; verily he yokes it again and thereby is it not exhausted. He, who yokes Agni where the yoking is to be performed, yokes him (best) among those who are yoking. 'O Agni [1], yoke thy (steeds)', 'Yoke them that best invoke the gods', he says;' this is the yoking of Agni; verily he yokes him, and yokes him (best) among those who are yoking. The theologians say, 'Should the fire be piled up with face down, or face upwards?' Now the fire is piled in the likeness of birds; if he were to pile it face downward, the libations would reach it behind; if upwards, it could not fly, it would not be heavenly for him; he puts down the human head towards the east, face upwards [2]; verily the libations reach it in the mouth; he does not pile it face upwards; verily it is heavenly for him. He offers with (a verse) addressed to Surya; verily he bestows sight upon it; twice he offers, for there are two eyes; he offers with the same verse, for sight is the same, for prosperity.
