यज्ञशिष्टाशिनः सन्तो मुच्यन्ते सर्वकिल्बिषैः।
भुञ्जते ते त्वघं पापा ये पचन्त्यात्मकारणात्।।3.13।।
3.13 By becoming partakers of the remembers of sacrifices, they become freed from all sins. But the unholy persons who cook for themselves, they incur sin.
3.13 Those persons who acire food materials solely for propitiating the Supreme Person abiding as the Self of Indra and other deities, and who, after cooking them, propitiate, through them, the Supreme Person as He is, and then sustain themselves on the remnants of oblations (made for such propitiation), they alone will be free of impurities which have resulted from beginningless evil and which are inimical to the vision of the self. But they are evil-minded, who acire for selfish use the things which the Supreme Being, abiding as the Self of Indra and other deities, has granted them for worshipping Him with, and use it all on the other hand for feeding themselves - they eat only sin. Turning away from the vision of the self, they cook only for being led to Naraka (for the expiation of the sin incurred thery). Sri Krsna says that, from the standpoint of the world as well as that of the scriptures, everything has its origin in sacrifice; and He speaks of the need for the performance of the sacrifices and of the blemish in not performing the same:
Yajnashishtaashinah santo muchyante sarva kilbishaih; Bhunjate te twagham paapaa ye pachantyaatma kaaranaat.
yajña-śhiṣhṭa—of remnants of food offered in sacrifice; aśhinaḥ—eaters; santaḥ—saintly persons; muchyante—are released; sarva—all kinds of; kilbiṣhaiḥ—from sins; bhuñjate—enjoy; te—they; tu—but; agham—sins; pāpāḥ—sinners; ye—who; pachanti—cook (food); ātma-kāraṇāt—for their own sake
