"Vaisampayana continued, 'Hearing these words of that God of gods, all those deities and great Rishis and Brahman became filled with such delight that the hair on their bodies stood on its end. They forthwith made arrangements for a sacrifice in honour of Vishnu according to the ordinances laid down in the Vedas. In that sacrifice, Brahman himself dedicated a portion of the offerings to Vishnu. The deities and the celestial Rishis also, after the manner of Brahman, dedicated similar portions each unto the great God. The portions, thus offered with great reverence unto Vishnu, were, in respect of both the measure and the quality of the articles used, according to the ordinances laid down for the Krita age. The deities and the Rishis and Brahman, in that sacrifice, adored the great God as one endued with the complexion of the Sun, as the foremost of Beings, situate beyond the reach of Tamas, vast, pervading all things, the Supreme Lord of all, the giver of boons, and possessed of puissance. Thus adored by them, the boon-giving and great God, invisible and bodiless, addressed those assembled celestials from heaven and said unto them:--"The offerings dedicated by you in this sacrifice have all reached me. I am gratified with all of you. I shall bestow rewards on you that will however, be fraught with ends whence there will be return.[1846] This shall be your distinctive feature, ye gods, from this day, in consequence of my grace and kindness for you. Performing sacrifices in every Yuga, with large presents, ye will become enjoyers of fruits born of Pravritti. Ye gods, those men also that will perform sacrifices according to the ordinances of the Vedas, will give unto all of you shares of their sacrificial offerings. In the Veda-sutras I make him the receiver (in such sacrifices) of a share similar to that which he has himself offered one in this sacrifice.
