Droṇa-parva Adhyāya 125: Duryodhana’s despair and vow after Jayadratha’s fall (जयद्रथवधे दुर्योधनविलापः)
इति श्रीमहाभारते द्रोणपर्वणि जयद्रथवधपर्वणि सात्यकिप्रवेशे दःशासनपराजये त्रयोविंशत्यधिकशततमो<ध्याय:
iti śrīmahābhārate droṇaparvaṇi jayadrathavadhaparvaṇi sātyakipraveśe daḥśāsanaparājaye trayoviṃśatyadhikaśatatamo 'dhyāyaḥ
Thus, in the Śrī Mahābhārata, within the Droṇa Parva—specifically in the section on the slaying of Jayadratha—ends the one-hundred-and-twenty-third chapter, whose theme is Sātyaki’s entry into the battle formation and the defeat of Duḥśāsana. This colophon sets the episode within the war’s larger moral struggle, where valor and loyalty stand against cruelty and adharma.
संजय उवाच
As a colophon, the verse does not teach through direct instruction; it frames the narrative ethically by marking a chapter centered on the triumph of disciplined valor and loyal intervention (Sātyaki’s advance) over cruelty and wrongdoing (Duḥśāsana’s defeat), within the broader dharmic reckoning of the war.
This is the closing colophon of the chapter: it situates the events within Droṇa Parva, in the Jayadratha-slaying section, and identifies the chapter’s focus as Sātyaki’s entry/advance in battle and the defeat of Duḥśāsana, concluding the 123rd chapter.
