Mbh 12.293.1b

One pays off the debts one owes to one's own self by listening to Vedic recitations and reflecting on their import, by eating the remnants of sacrifices, and by supporting one's body. One should duly discharge all the acts, from the beginning, that one owes to one's servants. Though destitute of wealth, men are seen to attain to success by great exertions.[1519] Munis by duly adoring the deities and by duly pouring libations of clarified butter on the sacred fire, have been seen to attain to ascetic success. Richika's son became the son of Vishwamitra. By adoring the deities who have shares in sacrificial offerings, with Richs (he attained to success in after life). Usanas became Sukra by having gratified the god of gods. Indeed, by hymning the praises of the goddess (Uma), he sports in the firmament, endued with great splendour.[1520] Then, again, Asita and Devala, and Narada and Parvata, and Karkshivat, and Jamadagni's son Rama, and Tandya possessed of cleansed soul, and Vasishtha, and Jamadagni, and Viswamitra and Atri, and Bharadwaja, and Harismasru, and Kundadhara, and Srutasravas,--these great Rishis, by adoring Vishnu with concentrated minds with the aid of Richs, and by penances, succeeded in attaining to success through the grace of that great deity endued with intelligence. Many undeserving men, by adoring that good deity, obtained great distinction. One should not seek for advancement by achieving any wicked or censurable act. That wealth which is earned by righteous ways is true wealth. Fie on that wealth, however, which is earned by unrighteous means. Righteousness is eternal. It should never, in this world, be abandoned from desire of wealth. That righteous-souled person who keeps his sacred fire and offers his daily adorations to the deities is regarded as the foremost of righteous persons. All the Vedas, O foremost of kings, are established on the three sacred fires (called Dakshina, Garhapatya, and Ahavaniya).
