भीमसेन–कर्णयुद्धवर्णनम्
Description of the Bhīmasena–Karṇa Engagement
तस्मिंस्तथा वर्तमाने दारुणे नादसंकुले
tasmiṁs tathā vartamāne dāruṇe nādasaṅkule
Sañjaya said: While that dreadful situation was unfolding in that manner—amid a tumult of terrifying battle-cries and clamor—
संजय उवाच
The line underscores the moral and psychological weight of war: when events become 'dāruṇa' (dreadful) and the world is 'nādasaṅkula' (choked with uproar), clarity and dharmic discernment are strained—highlighting how violence creates confusion and suffering even before specific deeds are described.
Sañjaya sets the scene for the next action by describing the battlefield atmosphere: a grim episode is in progress, and the surroundings are filled with the roar and tumult of combat.
