यज्ञशिष्टाशिनः who eat the remnants of the sacrifice, सन्तः the righteous, मुच्यन्ते are freed, सर्वकिल्बिषैः from all sins, भुञ्जते eat, ते those, तु indeed, अघम् sin, पापाः sinful ones, ये who, पचन्ति cook, आत्मकारणात् for their own sake. Commentary: Those who, after performing the five great sacrifices, eat the remnants of the food are freed from all the sins committed by these five agents of insect slaughter, viz., (1) the pestle and mortar, (2) the grinding stone, (3) the fireplace, (4) the place where the waterpot is kept, and (5) the broom. These are the five places where injury to life is daily committed.
