Bhagavad Gita: Chapter 3/Verse 13

यज्ञशिष्टाशिनः सन्तो मुच्यन्ते सर्वकिल्बिषैः ।
भुञ्जते ते त्वघं पापा ये पचन्त्यात्मकारणात् ॥३- १३॥

yajñaśiṣṭāśinaḥ santo mucyante sarvakilbiṣaiḥ ।
bhuñjate te tvaghaṃ pāpā ye pacantyātmakāraṇāt ॥3- 13॥

Those good who partake the remainder of devotion are liberated from all evils. But the evil ones who enjoy sin, they create sustenance from a position of self-interest.

Commentary

This verse is typically translated with a literal ritual sacrifice tone or a metaphorical one involving devotion. I choose the latter given I am using the word "devotion" in place of the word "sacrifice" throughout the verses in this chapter. The essence of this verse is that one needs to act with a sense of devotion for all without doing things for one's own self-interest.
