yadā kṛtāstro drupadaḥ pracinvañśirāṃsi yūnāṃ samare rathasthaḥ |
kruddhaḥ śaraiśchetsyati cāpamuktaistadā yuddhaṃ dhārtarāṣṭro'nvatapsyat || 32 ||

When Drupada, skilled in weapons, and seated on his car, desirous of plucking the heads of youthful warriors, will wrathfully strike them off with arrows shot from his bow, then will the son of Dhritarashtra repent for this war. When that slayer of hostile heroes, Virata will penetrate into the ranks of the foe, grinding all before him with the aid of his Matsya warriors of cool courage, then will the son of Dhritarashtra repent for this war. When he will behold in the very van the eldest son of the Matsya king, of cool courage and collected mien, seated on his car and accoutred in mail on behalf of the Pandavas, then will the son of Dhritarashtra. repent for this war. I tell thee truly that when that foremost of Kaurava heroes, the virtuous son of Santanu, will be slain in battle by Sikhandin, then all our foes, without doubt, will perish. Indeed, when, overthrowing numerous car-warriors, Sikhandin, seated on his own well-protected car, will proceed towards Bhishma, crushing multitudes of (hostile) cars by means of his own powerful steeds, then will the son of Dhritarashtra repent for this war. When he will behold Dhristadyumna unto whom Drona hath imparted all the mysteries of the science of weapons, stationed in splendour in the very van of the Srinjaya ranks, then will the son of Dhritarashtra repent.
