कर्णवधार्थं धनञ्जयस्य प्रतिज्ञा — Arjuna’s resolve for Karṇa’s defeat
ऐन्द्रमस्त्रममेयात्मा प्रादुश्चक्रे त्वरान्वित: । तदनन्तर भगवान् श्रीकृष्ण जिनके सारथि हैं, उन अमेय आत्मबलसे सम्पन्न श्वेतवाहन अर्जुनने होशमें आकर बड़ी उतावलीके साथ ऐन्द्रास्त्रका प्रयोग किया
aindram astram ameyātmā prāduścakre tvarānvitaḥ |
Sañjaya said: Endowed with immeasurable inner power, Arjuna—whose charioteer is the Blessed Śrī Kṛṣṇa—regained composure and, with urgent resolve, brought forth and deployed the Indra-weapon.
संजय उवाच
Even amid extreme danger, a dharmic warrior must recover composure and act with disciplined intention; power (astra) is to be employed under self-mastery and right guidance, not from uncontrolled fear or rage.
Sañjaya reports that Arjuna, with Kṛṣṇa as his charioteer, quickly manifests and deploys the Aindra (Indra) missile-weapon, indicating an escalation in the battle through the use of high celestial astras.
