Saumadatti-vadha and Bhīma–Alambusa-saṃyoga (सौमदत्तिवधः तथा भीमालम्बुससंयोगः)
इति श्रीमहाभारते द्रोणपर्वणि प्रतिज्ञापर्वणि अर्जुनस्य पुन: पाशुपतास्त्रप्राप्तौ एकाशीतितमो<ध्याय:
iti śrīmahābhārate droṇaparvaṇi pratijñāparvaṇi arjunasya punaḥ pāśupatāstraprāptau ekāśītitamo 'dhyāyaḥ
Thus, in the Śrī Mahābhārata, within the Droṇa Parva—specifically in the section called the Pratijñā Parva—ends the eighty-first chapter, describing Arjuna’s renewed attainment of the Pāśupata weapon. The colophon underscores the epic’s ethical frame: even amid vows and battlefield urgency, divine power is portrayed as something regained through worthiness and right conduct, not merely seized by force.
संजय उवाच
The colophon highlights an ethical principle common in the epic: extraordinary power (such as divine astras) is framed as something granted or regained through merit, discipline, and alignment with dharma—especially significant in a context of vows (pratijñā) and war.
This is the chapter-ending colophon stating that the eighty-first chapter of the Droṇa Parva (within the Pratijñā section) concludes, and that its subject is Arjuna’s renewed attainment of the Pāśupata weapon.
