Adhyāya 119: Vyāsa–Kīṭa-saṃvāda
Tapas-bala and karmic ascent across yoni
आत्मौपम्येन मन्तव्यं बुद्धिमद्धिः कृतात्मभि: । मृत्युतो भयमस्तीति विदुषां भूतिमिच्छताम्
ātmaupamyena mantavyaṃ buddhimadbhiḥ kṛtātmabhiḥ | mṛtyuto bhayam astīti viduṣāṃ bhūtim icchatām ||
Bhishma said: The wise and self-disciplined should judge by analogy with themselves—seeing all beings as they would see their own self. Even learned people who seek their own welfare live with fear of death; therefore how could blameless, healthy creatures who desire to live not feel fear when they are forcibly slain by sinful men who make their livelihood from flesh?
भीष्म उवाच
Use ātmaupamya—placing oneself in another’s position—as an ethical test: since everyone fears death and seeks well-being, one should not cause fear and harm to other living beings, especially the innocent.
In Anushasana Parva, Bhishma is instructing Yudhishthira on dharma and right conduct. Here he argues from a universal human experience—fear of death—to ground compassion toward all creatures and to condemn violent killing driven by appetite or livelihood.
