Mbh 14.91.2b

The deity of a hundred sacrifices, however, influenced by pride and overwhelmed by stupefaction, did not accept these words uttered by the Rishis. Then, O Bharata, a great dispute arose in that sacrifice of Sakra between the ascetics as to how sacrifices should be performed, that is, should they be performed with mobile creatures or with immobile objects. All of them were worn out with disputation. The Rishis then, those beholders of truth, having made an understanding with Sakra (about referring the matter to arbitration) asked king Vasu, "O highly blessed one, what is the Vedic declaration about sacrifices? Is it preferable to perform sacrifices with animals or with seeds and juices?" Hearing the question, king Vasu, without all judging of the strength or weakness of the arguments on the two sides, at once answered, saying, "Sacrifices may be performed with whichever of the two kinds of objects is ready." Having answered the question thus, he had to enter the nether regions. Indeed the puissant ruler of the Chedis had to undergo that misery for having answered falsely. Therefore, when a doubt arises, no person, however wise, should singly decide the matter, unless he be the puissant and self-born Lord himself of creatures. Gifts made by a sinner with an impure understanding, even when they are very large, become lost. Such gifts go for nothing. By the gifts made by a person of unrighteous conduct,--one, that is, who is of sinful soul and who is a destroyer, just fame is never acquired either here or hereafter. That person of little intelligence who, from desire of acquiring merit, performs sacrifices with wealth acquired by unrighteous means, never succeeds in earning merit. That low wretch of sinful soul, who hypocritically assuming a garb of righteousness makes gifts unto Brahmanas, only creates the conviction in men about his own righteousness (without earning true merit).
