Mahabharata Aswamedha Parva Chapter 91:2

Mahabharata Aswamedha Parva (Anugita Parva) Chapter 91:2 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). That Brahmana of uncontrolled conduct, who acquires wealth by sinful acts, ever overwhelmed by passion and stupefaction, attains at last to the goal of the sinful. Someone, overwhelmed by cupidity and stupefaction, becomes bent on strong wealth. He is seen to persecute all creatures, urged by a sinful and impure understanding. He who, having acquired wealth by such means, makes gifts or performs sacrifices therewith, never enjoys the fruits of those gifts or sacrifices in the other world in consequence of the wealth having been earned by unrighteous means. Men endued with wealth of penances, by giving away, to the best of their power, grains of corn picked up from the fields or roots or fruits or pot-herbs or water or leaves, acquire great merit and proceed to Heaven. Even such gifts, as also compassion to all creatures, and Brahmacharyya, truthfulness of speech and kindness, and fortitude, and forgiveness, constitute the eternal foundations of Righteousness which itself is eternal. We hear of Viswamitra and other kings of ancient times. Indeed, Viswamitra, and Asita, and king Janaka, and Kakshasena and Arshtisena, and king Sindhudwipa,—these and many other kings, endued with wealth of penances, having made gifts of articles acquired lawfully, have attained to high success. Those amongst Brahmanas and Kshatriyas and Vaisyas and Sudras who betake themselves to penances, O Bharata, and who purify themselves by gifts and other acts of righteousness, proceed to Heaven.'"
