Arjuna’s request to Krishna and the opening of the Kāśyapa–Brāhmaṇa mokṣa discourse (Āśvamedhika-parva 16)
जातीमरणतत्त्वज्ञं कोविदं पापपुण्ययो: । द्रष्टारमुच्चनीचानां कर्मभिवदेहिनां गतिम्
jātimaraṇatattvajñaṁ kovidaṁ pāpapuṇyayoḥ | draṣṭāram uccanīcānāṁ karmabhir dehināṁ gatiṁ ||
婆罗门说道:“他了知生与死的真实法则,于罪与福德之事亦能精审辨别。他亲见有身众生——无论尊卑——随其业行所至的归趣。”
ब्राह्मण उवाच
Moral causality governs embodied existence: beings attain higher or lower destinies in accordance with their actions, and true wisdom includes discerning the realities of birth, death, and the ethical weight of merit and sin.
The speaker (a Brahmin) describes an accomplished sage—one who understands birth and death and can discern merit and sin—portraying him as a direct witness of how different beings reach their respective destinies through karma.
