5.52

Medhātithi’s commentary (manubhāṣya):
This deprecates the man who eats meat for the purposc of fattening himself, and not one who does it for averting disease. That this is so is clear from the words of the text ‘he who seeks to increase.’ In him also, only if he does it ‘without worshipping the Gods and Pitṛs.’ But if the man is ill, and recovery is not possible without eating meat, then there would be no harm, even if the said worshipping were not done.—(52).

“In the Mahābhārata (13.114.14) this verse is ascribed to Nārada.”—Hopkins.

This verse is quoted in Vīramitrodaya (Āhnika, p. 531);—and in Smṛtisāroddhāra (p. 301).
