Mbh 7.12.1a

“Sanjaya said, ‘Yes, as I saw everything with my own eyes, I will describe to thee how Drona fell down, slain by the Pandavas and the Srinjayas. Having obtained the command of the troops, that mighty car-warrior, viz., Bharadwaja’s son, said these words unto thy son in the midst of all the troops, “Inasmuch as, O king, thou hast honoured me with the command of the troops immediately after that bull among the Kauravas, viz., the son of the Ocean-going (Ganga), take thou, O Bharata, the adequate fruit of that act of thine. What business of thine shall I now achieve? Ask thou the boon that thou desirest.” Then king Duryodhana having consulted with Karna and Duhsasana and others, said unto the preceptor, that invincible warrior and foremost of all victors, these words, “If thou wouldst give me a boon, then, seizing that foremost of car-warriors, viz., Yudhishthira, alive, bring him unto me here.” Then that preceptor of the Kurus, hearing those words of thy son, returned him the following answer, gladdening all the troops therewith. “Praised be Kunti’s son (Yudhishthira) whose seizing only thou desirest. O thou that art difficult of being vanquished, thou askest not any other boon (one for example) for his slaughter. For what reason, O tiger among men, dost thou not desire his death? Thou art, without doubt, O Duryodhana, not ignorant of policy. Why, therefore, dost thou not allude to Yudhishthira’s death? It is a matter of great wonder that king Yudhishthira, the just, hath no enemy desirous of his death. Inasmuch as thou wishest him to be alive, thou (either) seekest to preserve thy race from extinction, or, O chief of the Bharatas, thou, having vanquished the Pandavas in battle, art desirous of establishing brotherly relation (with them) by giving them their kingdom. Auspicious was the birth of that intelligent prince. Truly is he called Ajatasatru (the foeless one), for even thou bearest affection for him.”
