Mahabharata — Anushasana Parva, Shloka 17
Dvaipāyana–Kīṭa Saṃvāda: Karmic Memory, Fear of Death, and Embodied Pleasure
(भस्म विष्ठा कृमिर्वापि निष्ठा यस्येदृशी ध्रुवा । स काय: परपीडाभि: कथं धार्यों विपश्चिता ।।
bhasma viṣṭhā kṛmir vāpi niṣṭhā yasyedṛśī dhruvā | sa kāyaḥ parapīḍābhiḥ kathaṃ dhāryo vipaścitā ||
ビーシュマは言った。「この身には、次の三つの結末のいずれかが必ず、しかも避けがたく定まっている。すなわち灰となるか、ある生き物に食われて糞穢となるか、あるいは捨てられて虫にたかられるかである。これを知りながら、賢者がどうして他者に苦痛を与え（その肉を求めて）この身を養い保つことができようか。肉食を称賛することさえ、罪の業とその報いに人を絡め取るのだ。」

Educational Q&A
The body’s end is inevitably decay—ashes, excrement, or worms—so a discerning person should not nourish it through violence to other beings; endorsing meat-eating is portrayed as binding one to sinful karma and its results.
In Anushasana Parva’s dharma instruction, Bhishma continues advising on righteous conduct, using stark images of the body’s fate to argue against harming others for bodily sustenance, especially in the context of consuming or praising meat.
