यज्ञशिष्टाशिनः सन्तो मुच्यन्ते सर्वकिल्बिषैः।
भुञ्जते ते त्वघं पापा ये पचन्त्यात्मकारणात्।।3.13।।
।।3.13।। यज्ञ के अवशिष्ट अन्न को खाने वाले श्रेष्ठ पुरुष सब पापों से मुक्त हो जाते हैं किन्तु जो लोग केवल स्वयं के लिये ही पकाते हैं वे तो पापों को ही खाते हैं।।
In a very rational way Lord Krishna is praising the saintly performers of yagna by means of worship and offerings and censoring those who fail to perform such yagna. In the previous three verses and this one Lord Krishna has elucidated the science of yagna. The Purusha Sukta in the Rig Veda we see that Brahma the first born is the Purusha offering himself as worship and oblations for the benefit and welfare of creation. By Brahma inaugurating the act of yagna, the perennial principles of existence or dharma were established for all the worlds. Thus by ordaining dharma the Supreme Lord Krishna through his representative Brahma has given mankind the purpose, the objective and the methodology of yagna. One in wisdom should follow in the footsteps of Brahma and offer to the Supreme Lord there very self and essence as an act of worship in yagna.
