Āścarya-kathana: Brāhmaṇa–Nāga Dialogue on Sūrya (Vivasvat) and the ‘Second Sun’ Phenomenon
त्वं कर्ता युगधर्माणां निराशी: कर्मसंज्ञितम् । अमिततेजस्वी ब्रह्माको इस धर्मका उपदेश देकर उस समय भगवानने उनसे कहा --/तुम निष्कामभावसे सारे कर्म करते हुए युगधर्मोके प्रवर्तक बनो”
tvaṁ kartā yugadharmāṇāṁ nirāśī karma-saṁjñitam | amitatejasvī brahmā ko ’sya dharmasyopadeśaṁ dattvā tasmin kāle bhagavān uvāca—tvaṁ niṣkāma-bhāvena sarvāṇi karmāṇi kurvan yugadharmāṇāṁ pravartako bhava |
ヴァイシャンパーヤナは語った。「汝は諸時代にふさわしきダルマの確立者となるべし。報いを望まず、いわゆる『行為（カルマ）』をなせ。このダルマを授け終えると、福徳具足の主はその時こう告げた。『欲を離れた心で一切の務めを果たし、この時代の正しき秩序を動かし始める者となれ。』」

Educational Q&A
The verse teaches niṣkāma-karma: one should perform all duties without craving the fruits, and thereby uphold and establish yuga-dharma—the ethical order appropriate to one’s time.
Vaiśampāyana reports a moment of instruction: after teaching ‘this dharma,’ the divine speaker exhorts the listener to act selflessly and become an initiator of righteous norms for the age.
