Śānti-parva 168: Śoka-nivṛtti-buddhi (The Cognition that Reduces Grief) and Piṅgalā’s Nairāśya
इस प्रकार श्रीमयहाभारत थान्तिपर्वके अन्तर्गत आपद्धर्मपर्वमें खड॒गकी उत्पत्तिका कथनविषयक एक सौ छाछठवाँ अध्याय पूरा हुआ
iti prakāraḥ śrīmahābhārate śāntiparvaṇi antaragate āpaddharmaparvaṇi khaḍgasya utpattikathana-viṣayakaḥ ekaśata-ṣaṭṣaṣṭitamaḥ adhyāyaḥ pūrṇaḥ
इति श्रीमहाभारते शान्तिपर्वणि आपद्धर्मपर्वणि खड्गोत्पत्तिवर्णने षट्षष्ट्यधिकशततमोऽध्यायः समाप्तः॥
भीष्म उवाच
As a colophon, the verse itself teaches indirectly: it frames the preceding discussion as Āpaddharma—ethical guidance for crisis—where the ‘origin of the sword’ symbolizes the emergence of coercive power used to protect society and uphold order when ordinary norms fail.
This is the chapter-ending statement: it announces that the 166th chapter of the Āpaddharma section within Śānti Parva has concluded, and that its topic was the narration of the sword’s origin.
