Droṇa-parva Adhyāya 125: Duryodhana’s despair and vow after Jayadratha’s fall (जयद्रथवधे दुर्योधनविलापः)
हत्वा पञज्चशतान् योधान् शरैराशीविषोपमै:
hatvā pañcaśatān yodhān śarair āśīviṣopamaiḥ
Sañjaya said: Having slain five hundred warriors with arrows like venomous serpents, he left the battlefield strewn with the fallen—an image of war’s swift, impersonal lethality, where prowess becomes inseparable from moral cost.
संजय उवाच
The verse underscores the terrifying efficiency of martial skill: weapons can act with the suddenness and inevitability of poison. In the Mahābhārata’s ethical frame, such prowess is not celebrated without remainder; it intensifies the tension between kṣatriya-duty in war and the human cost that accrues as karmic and moral burden.
Sañjaya reports a moment of extreme slaughter on the battlefield: a single combatant (implied by context) kills five hundred warriors using arrows described as ‘like venomous serpents,’ emphasizing speed, deadliness, and the panic such an assault creates among troops.
