Sanskrit Original
तुर्वसोर वह्निर आत्मजो वह्नेर गोभानुस ततश च त्रैशानुस तस्माच च करंधमः। तस्यापि मरुत्तः। सो ऽनपत्यो ऽभवत। ततश च पौरवं दुष्यन्तं पुत्रम अकल्पयत। एवं ययातिशापात तद्वंशः पौरवम वंशं समाश्रितवान।।
turvasor vahnir ātmajo vahner gobhānus tataś ca traiśānus tasmāc ca karaṃdhamaḥ| tasyāpi maruttaḥ| so 'napatyo 'bhavat| tataś ca pauravaṃ duṣyantaṃ putram akalpayat| evaṃ yayātiśāpāt tadvaṃśaḥ pauravam vaṃśaṃ samāśritavān||
Turvasu's son was Vahni, and from Vahni came Gobhanu. From him came Traishanu, and from him came Karandhama. He had no offspring. Then he begot a son named Dushyanta from the Paurava lineage. Thus, due to Yayati's curse, that lineage became associated with the Paurava lineage.
