इति श्रीमहाभारते भीष्मपर्वणि भीष्मवधपर्वणि भीष्मदुर्योधनसंवादे नवाधिकशततमोडध्याय:
iti śrīmahābhārate bhīṣmaparvaṇi bhīṣmavadhaparvaṇi bhīṣma-duryodhana-saṃvāde navādhikaśatatamo 'dhyāyaḥ
Thus, in the Śrī Mahābhārata, within the Bhīṣma Parva—specifically in the section concerning Bhīṣma’s fall—during the dialogue between Bhīṣma and Duryodhana, ends the one hundred and ninth chapter. This closing colophon frames the narrative as a morally charged war-episode: the fall of a great elder-warrior and the counsel exchanged amid the ethical collapse of fratricidal conflict.
संजय उवाच
As a colophon, the verse does not teach through direct instruction; it frames the episode ethically by marking that the narrative belongs to the account of Bhīṣma’s fall and his exchange with Duryodhana—highlighting how counsel, duty, and moral responsibility are tested amid war.
This is the formal closing line of a chapter: Sañjaya signals that the chapter concludes within the Bhīṣma Parva, in the subsection dealing with Bhīṣma’s downfall, specifically during the Bhīṣma–Duryodhana conversation.
