Droṇa-parva Adhyāya 125: Duryodhana’s despair and vow after Jayadratha’s fall (जयद्रथवधे दुर्योधनविलापः)
दृष्टवा दुःशासनं राजा तथा शरशताचितम्
dṛṣṭvā duḥśāsanaṃ rājā tathā śaraśatācitam
Sañjaya said: Seeing Duḥśāsana—covered and heaped with hundreds of arrows—the king was struck by the grim reality of war’s consequences, for the sight of a fallen kinsman laid bare the moral cost of rage and wrongdoing on the battlefield.
