Shloka 76
Adhyāya 119: Vyāsa–Kīṭa-saṃvāda
Tapas-bala and karmic ascent across yoni
एतत्ते कथितं राजन् मांसस्य परिवर्जने । प्रवृत्ती च निवृत्ती च विधानमृषिनिर्मितम्
etatte kathitaṃ rājan māṃsasya parivarjane | pravṛttī ca nivṛttī ca vidhānam ṛṣinirmitam ||
ビーシュマは言った。「王よ、わたしは汝に、肉を断つことについてこのように説き明かした――さらに、プラヴリッティとニヴリッティ（世に関わる行と退く行）の双方を統べる原理、すなわち仙賢リシたちが定めた行法の規範をも併せて示したのである。この教えにおいて節制は、単なる禁令ではなく、古のリシが立てた法度に根ざすダルマの修行として説かれている。」
भीष्म उवाच
Educational Q&A
Bhishma summarizes that the dharmic rationale for abstaining from meat has been explained, along with the broader framework of pravṛtti (engaged life) and nivṛtti (withdrawal/renunciation). The point is that ethical restraint is grounded in an authoritative, sage-formulated code rather than personal preference.
In Anushasana Parva, Bhishma instructs the king (Yudhishthira) on dharma while lying on the bed of arrows. Here he concludes a segment on avoiding meat and situates it within the larger rishi-sanctioned system that distinguishes duties of active worldly life and duties of renunciatory withdrawal.
