Mbh 12.293.1a

"'"Parasara said, 'Nobody in this world does good to another. Nobody is seen to make gifts to others. All persons are seen to act for their own selves. People are seen to cast off their very parents and their uterine brothers when these cease to be affectionate. What need be said then of relatives of other degrees?[1517] Gifts to a distinguished person and acceptance of the gifts made by a distinguished person both lead to equal merit. Of these two acts, however, the making of a gift is superior to the acceptance of a gift.[1518] That wealth which is acquired by proper means and increased also by proper means, should be protected with care for the sake of acquiring virtue. This is an accepted truth. One desirous of acquiring righteousness should never earn wealth by means involving injury to others. One should accomplish one's acts according to one's power, without zealously pursuing wealth. By giving water, whether cold or heated by fire, with a devoted mind, unto a (thirsty) guest, according to the best of one's power, one earns the merit that attaches to the act of giving food to a hungry man. The high-souled Rantideva obtained success in all the worlds by worshipping the ascetics with offerings of only roots and fruits and leaves. The royal son of Sivi also won the highest regions of felicity by having gratified Surya along with his companion with offerings of the same kind. All men, by taking birth, incur debts to gods, guests, servants, Pitris, and their own selves. Everyone should, therefore, do his best for freeing himself from those debts. One frees oneself from one's debt to the great Rishis by studying the Vedas. One pays off one's debts to the gods by performing sacrifices. By performing the rites of the Sraddha one is freed from one's debts to the Pitris. One pays off one's debt to one's fellowmen by doing good offices to them.
