The Mahabharata of Krishna-Dwaipayana Vyasa…
“ The Dakshina that is presented to a lying or deceitful person destroys both the giver and the receiver without benefiting them in any respect. Such a Dakshina is destructive and highly censurable. The Pitris of the person making it have to fall down from the path of the deities. The gods know them to be Brahmanas who always tread, O Yudhishthira, within the bounds set up by the Rishis who are conversant with all duties, and who have a firm faith in their efficacy. Those Brahmanas that are devoted to Vedic study, to knowledge, to penances, and to acts, O Bharata, should be known as Rishis. ”
