YV 5.5b

When about to consecrate himself, he offers to Agni and Visnu on eleven potsherds; all the deities are Agni; the sacrifice is Visnu; verily he lays hold of the deities and the sacrifice; Agni is the lowest of the deities, Visnu the highest; in that he offers to Agni and Visnu on eleven potsherds, the sacrificer envelops the gods [4] on both sides and wins them. By the cake the gods prospered in yonder world, by the oblation in this; he who desires, 'May I prosper in yonder world', should offer a cake; verily he prospers in yonder world. In that it is offered on eight pot sherds, it is connected with Agni, in that it is offered on three potsherds, it is connected with Visnu; (verily it serves) for prosperity. He who desires, 'May I prosper in the world', should offer an oblation; the ghee belongs to Agni, the rice grains to Visnu, therefore [5] an oblation should be offered; verily he prospers in this world. It is (an offering) to Aditi; Aditi is this (earth); verily he finds support in this (earth); verily also be extends the sacrifice over this. He who piles the fire without keeping it in the pan for a year-(it is with him) as when an embryo is dropped prematurely would go to ruin; he should offer before (the others) on twelve potsherds to Vaiçvanara; Agni Vaiçvanara is the year; even as (an embryo) attaining a year's growth [61 is born when the due season' is come, so he having obtained the year when the due season is come, piles the fire; he goes not to ruin. Vaiçvanara is the form dear to Agni; verily he wins the form dear to him. These offerings are three; these worlds are three; (verily they serve) for the mounting of these worlds. Prajapati after creating creatures in affection entered into them; from them he could not emerge; he said, 'He shall prosper who shall pile me again hence.' The gods piled him; then they prospered; in that they piled him, that is why the piling has its name. He who knowing thus piles the fire is prosperous.
