1.7.69

iti manusmaraṇāt | tathā gṛhe 'pi nivasan brāhmaṇādiś cātuvarṇiko munivan mānanīyo bhavati māṃsatyāgāt | etac ca na pratiṣiddhamāṃsaviṣayaṃ nāpi prokṣitādiviṣayam kiṃ tu pāriśeṣyād atithyādyarcanāvaśiṣṭābhyanujñātaviṣayam iti || 1.181 ||

—owing to this statement of tradition by Manu. Likewise, though living at home, a Brahmin or other member of the four classes becomes venerable like a sage through the abandonment of meat. And this does not concern forbidden meat, nor does it concern meat consecrated by sprinkling and the like; rather, by residual inference, it concerns what is permitted as the remainder from the worship of guests and the like. || 1.181
