Shloka 12
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 ||
那罗陀说道：“迦尔纳之败，乃多因并至：毗湿摩曾轻辱于他；在评定诸大车战士之列时，他屡屡只被称作‘半车战士’；沙利耶设法削弱他的光彩与自信；又因婆苏提婆（奎师那）以谋略之政，使局势转而不利于他。由是侮辱、名位贬抑、心志动摇与神圣的治略交织，遂成其覆亡。”

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.
