Saumadatti-vadha and Bhīma–Alambusa-saṃyoga (सौमदत्तिवधः तथा भीमालम्बुससंयोगः)
द्वितीयं चापरं नागं सहस्रशिरसं वरम् । वमन्तं विपुला ज्वाला ददृशातेडग्निवर्चसम्,वहीं उन्होंने अग्निके समान तेजस्वी और सहस्र फणोंसे युक्त दूसरा श्रेष्ठ नाग भी देखा, जो अपने मुखसे आगकी प्रचण्ड ज्वालाएँ उगल रहा था
dvitīyaṃ cāparaṃ nāgaṃ sahasraśirasaṃ varam | vamantaṃ vipulā jvālā dadṛśāteḍagnivarcasaṃ ||
Sañjaya said: They beheld yet another noble serpent, the second—an excellent nāga with a thousand heads—blazing like fire, as it spewed forth vast, fierce tongues of flame from its mouth.
संजय उवाच
The verse uses a terrifying, fire-bright nāga as an omen-like image to highlight how adharma-driven conflict manifests as overwhelming, uncontrollable destructive force; it cautions that war unleashes powers that consume indiscriminately.
In Sañjaya’s report, the observers witness a second extraordinary serpent—thousand-headed and radiant like fire—spewing great flames, intensifying the scene’s sense of dread and portent amid the events of the Drona Parva.
