5.47.22

tyaktātmānaḥ pārthivāyodhanāya samādiṣṭā dharmarājena vīrāḥ |
rathaiḥ śubhraiḥ sainyamabhidravanto dṛṣṭvā paścāttapsyate dhārtarāṣṭraḥ || 22 ||

Accustomed to enjoy all the comforts and luxuries of life, when Nakula, recollecting that bed of woe on which he had slept for a long time in the woods, will vomit the poison of his wrath like an angry snake, then will the son of Dhritarashtra repent for this war. Ready to lay down their very lives, the (allied) monarchs, O Suta, urged to battle by king Yudhishthira the just, will furiously advance on their resplendent cars against the (hostile) army. Beholding this, the son of Dhritarashtra will certainly have to repent. When the Kuru prince will behold the five heroic sons of (Draupadi), tender in years but not in acts, and all well-versed in arms, rush, reckless of their lives, against the Kauravas, then will that son of Dhritarashtra repent for this war. When bent upon carnage Sahadeva, mounted on his car of noiseless wheels, and motion incapable of being obstructed, and set with golden stars, and drawn by well-trained steeds, will make the heads of monarchs roll on the field of battle with volleys of arrows,--indeed, beholding that warrior skilled in weapons, seated on his car in the midst of that frightful havoc, turning now to the left and now to the right and falling upon the foe in all directions, then will the son of Dhritarashtra repent for this war.
