YV 3.2h

There are three cakes, these worlds are three; (verily they serve) to obtain these worlds; each one above the other is larger, for so as it were are these worlds; (verily they serve) for prosperity; he cuts off from all (the cakes) as he sets them up without making a failure; be recites (the verses) alternating, to prevent burning. The gods and the Asuras were in conflict: the Asuras conquered the gods, the gods being defeated became the servants of the Asuras; from them power and strength departed; Indra perceived this; he departed in pursuit of it; he could not win it. Then he departed from it, he had recourse to Prajapati; he made him sacrifice with this (offering) with all the Prstha (Stotras); verily with it he bestowed upon him power and strength. Him who desires power [1], desires strength, he should make him sacrifice with this (offering) with all the Prsthas; verily he has recourse to these deities with their own share; verily they bestow upon him power and strength. In that he offers to Indra of the Rathantara, verily he wins the brilliance of Agni; in that (he offers) to Indra of the Brhat, verily he wins the brilliance of Indra; in that (he offers) to Indra of the Vairupa, verily he wins the brilliance of Savitr [2]; in that (he offers) to Indra of the Vairaja, verily he wins the brilliance of the creator; in that (he offers) to Indra of the Çakvara, verily he wins the brilliance of the Maruts; in that (he offers) to Indra of the Raivata, verily he wins the brilliance of Brhaspati. So many are the brilliances, verily he wins them; he places (the cakes) on potsherds face upwards, for variety; the cake is on twelve potsherds [3], to secure the All-gods. He cuts off all around; verily all around he bestows on the sacrificer power and strength; he recites (the verses) alternating, to prevent burning. A horse, a bull, a ram, a goat, these are the sacrificial fee; for manliness.
