इति श्रीमहाभारते वनपर्वणि कुण्डलाहरणपर्वणि सूर्यकर्णसंवादे त्रिशततमो<ध्याय:
iti śrīmahābhārate vanaparvaṇi kuṇḍalāharaṇaparvaṇi sūryakarṇasaṃvāde triśatatamo 'dhyāyaḥ
Thus, in the Śrī Mahābhārata, within the Vana Parva, in the section concerning the taking away of the earrings, in the dialogue between Sūrya and Karṇa, ends the three-hundredth chapter. This colophon signals the close of a morally charged episode in which Karṇa’s identity, generosity, and the consequences of vows and gifts are foregrounded through divine counsel and human resolve.
कर्ण उवाच
As a colophon, the line itself teaches by framing the episode: it highlights that the Sūrya–Karṇa dialogue belongs to the ‘taking of the earrings’ narrative, where generosity, steadfastness to one’s word, and the ethical cost of gifts given under pressure are central concerns.
This is the closing formula marking the end of the three-hundredth chapter in the Vana Parva, specifically the section about the removal/taking of Karṇa’s earrings, presented through a dialogue between Sūrya and Karṇa.
