उपदिष्टो वधोपाय: कर्णस्य गुरुणा स्वयम् | व्यायच्छतश्न खड्गेन द्विधा खड्गं चकार ह,“गुरु द्रोणाचार्यने स्वयं ही कर्णको अभिमन्युके वधका उपाय बताया था और जब वह तलवार लेकर परिश्रमपूर्वक युद्ध कर रहा था, उस समय उन्होंने ही उसकी तलवारके दो टुकड़े कर दिये थे
upadiṣṭo vadhopāyaḥ karṇasya guruṇā svayam | vyāyacchataś ca khaḍgena dvidhā khaḍgaṃ cakāra ha ||
Sañjaya said: Karṇa had been personally instructed by his teacher in the method of killing; yet, while Karṇa was straining in combat with his sword, the teacher himself struck and split that sword into two. The episode underscores the moral tension of war, where knowledge meant to secure victory can be turned against its bearer, and where the authority of a guru may override ordinary expectations of loyalty and fairness on the battlefield.
