By the Brahman class he piled its front half, by the lordly class its right wing, by cattle its tail, by the people its left wing, by hope its middle. He who knowing thus piles the fire piles it with the seasons; verily he wins all [1]; they hearken to him who has piled the fire, he eats food, he is resplendent. The first layer is this (earth), the mortar the plants and trees; the second is the atmosphere, the mortar the birds; the third is yonder (sky), the mortar the Naksatras; the fourth the sacrifice, the mortar the sacrificial fee; the fifth the sacrificer, the mortar offspring; if he were to pile it with three layers, he would obstruct the sacrifice, the fee, the self, offspring; therefore should it be piled with five layers; verily he preserves all. In that there [2] are three layers, (it is) since Agni is threefold; in that there are two (more), the sacrificer has two feet, (it is) for support; there are five layers, man is five fold; verily he preserves himself. There are five layers, he covers (them) with five (sets of) mortar, these make up ten, man has ten elements; he preserves man in his full extent. Again the Viraj has ten elements, the Viraj is food; verily he finds support in the Viraj and the eating of food. The sixth layer is the year, mortar is the seasons; there are six layers, six (sets of) mortar, they make up twelve, the year has twelve months; verily he finds support in the year. The Horse Sacrifice (continued) The red, the dark red, the jujube red, these are for Prajapati; the brown, the reddish- brown, the parrot brown, these are for Rudra. The white, the white-eyed, the white- necked, these have the fathers as their deities. Three black barren cows are for Varuna, three white barren cows for the Sun; the dusky-spotted hornless ones are for Mitra and Brhaspati.
