अत्र चक्रधनुर्नाम सूर्याज्जातो महानृषि:
atra cakradhanuḥ nāma sūryāj jāto mahān ṛṣiḥ
Here, too, there was a great sage named Cakradhanu, born of the Sun. The narration invokes a solar-born seer to ground the ensuing account in sacred lineage and moral authority, suggesting that the counsel or precedent being cited is not merely worldly strategy but sanctioned by venerable tradition.
युपर्ण उवाच
The verse establishes moral and narrative authority by citing an eminent, solar-born ṛṣi. In the Mahābhārata, invoking such lineage signals that the guidance or example to follow is rooted in dharmic tradition rather than mere expediency.
Yuparṇa introduces a figure: a great sage named Cakradhanu, said to be born from Sūrya. This functions as a transition into a related account or precedent connected with that sage.
