Mahabharata — Anushasana Parva, Shloka 6
Adhyāya 119: Vyāsa–Kīṭa-saṃvāda
Tapas-bala and karmic ascent across yoni
भीष्मजीने कहा--राजन्! कुरुनन्दन! मांस न खानेसे जो धर्म होता है, उसका मुझसे यथार्थ वर्णन सुनो तथा उस धर्मकी जो उत्तम विधि है, वह भी जान लो ।।
Bhīṣma uvāca—Rājan! Kurunandana! māṁsaṁ na khādanena yo dharmo bhavati, tasya me yathārthaṁ varṇanaṁ śṛṇu, tathā ca tasya dharmasya yā uttamā vidhir api tāṁ jānīhi. Rūpam avyāṅgatām āyur buddhiṁ sattvaṁ balaṁ smṛtim prāptukāmair naraḥ hiṁsā varjitā vai mahātmabhiḥ.
毗湿摩说道：“大王啊，俱卢族之荣光！请听我如实陈说由不食肉而生的法（达摩），并知晓奉行此法的最上之道。凡欲得容貌端丽、形体无缺、寿命绵长、智慧明达、内心坚稳、气力充盛与记忆牢固者，当舍弃暴害；诚然，大心之人皆避不伤害一切有情。”

Educational Q&A
Bhishma teaches that abstaining from meat is grounded in ahiṁsā (non-violence), and that those seeking both bodily well-being (beauty, health, longevity) and mental excellence (intelligence, steadiness, memory) should avoid harming living beings; this restraint is upheld by the noble.
In the Anuśāsana Parva’s instruction section, Bhishma addresses the king (Yudhiṣṭhira) and begins an ethical exposition: he frames meat-abstinence as a dharma, promises to explain its proper practice, and links it to the broader principle of renouncing violence.
