Adhyāya 5 (Śānti-parva): Nārada’s account of Karṇa—Jarāsandha encounter and the causal grounds of Karṇa’s fall
भीष्मावमानात् संख्यायां रथस्यार्धानुकीर्तनात् । शल्यात् तेजोवधाच्चापि वासुदेवनयेन च
bhīṣmāvamānāt saṅkhyāyāṃ rathasyārdhānukīrtanāt | śalyāt tejovadhāccāpi vāsudevanayena ca ||
Narada said: “Karna was defeated for many converging reasons: because Bhishma had slighted him; because, in the reckoning of great chariot-warriors, he was repeatedly mentioned only as ‘half a ratha-warrior’; because Shalya worked to sap his brilliance and confidence; and also because Vasudeva (Krishna), through his strategic policy, acted in ways that turned the course against him. Thus, through insult, diminished standing, psychological undermining, and divine statesmanship, his fall was brought about.”
नारद उवाच
The verse frames defeat as multi-causal: social dishonor (avamāna), public ranking and reputation (saṅkhyā/anukīrtana), inner strength being eroded (tejo-vadha), and superior strategy (vāsudeva-naya). Ethically, it warns that pride, wounded honor, and hostile counsel can weaken even a powerful person, while wise policy can decisively shape outcomes.
Narada explains why Karna ultimately fell in the Kurukshetra war: Bhishma’s disparagement and repeated labeling as ‘half a ratha-warrior’ diminished his standing; Shalya’s conduct as charioteer worked against Karna’s morale and brilliance; and Krishna’s strategic interventions favored Karna’s opponents, collectively leading to Karna’s defeat.
