Mbh 12.79.4a

"'Bhishma said, "No man acquires blessedness or merit by disregarding the Vedas or by deceit or falsehood. Never think that it is otherwise. Dakshina constitutes one of the limbs of sacrifice and conduces to the nourishment of the Vedas. A sacrifice without Dakshina can never lead to salvation. The efficacy, however, of a single Purnapatra is equal to that of any Dakshina, however rich. Therefore, O sire, everyone belonging to the three orders should perform sacrifices.[239] The Vedas have settled that Soma is as the king himself to the Brahmanas. Yet they desire to sell it for the sake of performing sacrifices, though they never wish to sell it for gaining a livelihood. Rishis of righteous behaviour have declared, agreeably to the dictates of morality, that a sacrifice performed with the proceeds of the sale of Soma serves to extend sacrifices.[240] These three, viz., a person, a sacrifice and Soma, must be of good character. A person that is of bad character is neither for this nor for the other world. This audition has been heard by us that the sacrifice which high-souled Brahmanas perform by wealth earned by excessive physical labour, is not productive of great merit. There is a declaration in the Vedas that penances are higher than sacrifices. I shall now speak to thee of penances. O learned prince, listen to me. Abstention from injury, truthfulness of speech, benevolence, compassion,--these are regarded as penances by the wise and not the emaciation of the body. Disregard of the Vedas, disobedience to the dictates of the scriptures, and violation of all wholesome restraints, are productive of self-destruction. Listen, O son of Pritha, to what has been laid down by those that pour ten libations upon the fire at ten times of the day.--For them that perform the sacrifice of penance, the Yoga they endeavour to effect with Brahma is their ladle; the heart is their clarified butter; and high knowledge constitutes their Pavitra.
