मधुपर्के च यज्ञे च पितृदैवतकर्मणि । अत्रैव पशवो हिंस्या नान्यत्रैत्यब्रवीन् मनुः ॥ ४१ ॥
On offering the honey-mixture (to a guest), at a sacrifice and at the rites in honour of the manes, but on these occasions only, may an animal be slain; that (rule) Manu proclaimed.
A twice-born man who, knowing the true meaning of the Veda, slays an animal for these purposes, causes both himself and the animal to enter a most blessed state.
A twice-born man of virtuous disposition, whether he dwells in (his own) house, with a teacher, or in the forest, must never, even in times of distress, cause an injury (to any creature) which is not sanctioned by the Veda.
या वेदविहिता हिंसा नियताऽस्मिंश्चराचरे । अहिंसामेव तां विद्याद् वेदाद् धर्मो हि निर्बभौ ॥ ४४ ॥
Know that the injury to moving creatures and to those destitute of motion, which the Veda has prescribed for certain occasions, is no injury at all; for the sacred law shone forth from the Veda.
