Jñāna-yoga and Karma-phala: Manu–Bṛhaspati on Akṣara and the Limits of Mantra
यजुषा संस्कृतं मांसं निवृत्तो मांसभक्षणात् | न भक्षयेद् वृथामांसं पृष्ठमांसं च वर्जयेत्
yajuṣā saṃskṛtaṃ māṃsaṃ nivṛtto māṃsabhakṣaṇāt | na bhakṣayed vṛthāmāṃsaṃ pṛṣṭhamāṃsaṃ ca varjayet |
毗湿摩说道：既已戒除食肉之人，即便是以《夜柔吠陀》真言作过仪式加持的肉，也不应食用；又当远离无正当缘由所得之肉，以及施行祭祖仪式（śrāddha）后所余之肉。

Educational Q&A
If one has adopted abstinence from meat, one should maintain consistency and not make exceptions even for ritually sanctified meat; one should also avoid meat eaten without necessity and meat remaining from śrāddha/ritual contexts. The verse emphasizes integrity in ethical vows over loopholes.
In the Śānti Parva’s dharma instruction, Bhishma is advising Yudhiṣṭhira on conduct and restraint. Here he addresses dietary discipline, distinguishing between ritual sanction and personal renunciation, and urges the renouncer to avoid all forms of meat consumption.
