Mbh 8.88.1d

Yudhishthira is always engaged in the good of all creatures. Vrikodara is obedient to him. So also are the twins. Peace being made between thee and the Parthas, all creatures will be benefited, through, as it would seem, thy desire. Let the kings that are still alive go back to their homes. Let the troops abstain from hostilities. If thou dost not listen to my words, O king, struck by foes in battle, thou wilt have to burn with grief. Thou hast beheld, as well as the universe, what has been achieved by the single-handed Arjuna decked with diadem and garlands. The slayer of Vala himself could not achieve its like, nor the Destroyer, nor Prachetas, nor the illustrious king of the Yakshas. Dhananjaya, as regards his merits, is even much greater than that. He will never transgress whatever I say unto him. He will always follow thee. Be thou gratified, O king, for the benefit of the universe. Thou always honourest me greatly. I, too, bear a great friendship for thee. It is for this that I say so unto thee. I shall dissuade Karna also, provided thou art inclined to peace. Discerning persons say that there are four kinds of friends, viz., those that are naturally so, those that are made so by conciliation, those that become so through wealth, and lastly those brought under subjection by the exercise of power. All these elements are owned by thee with regard to the sons of Pandu. The Pandavas, O hero, are naturally thy friends. Obtain them again as friends for certain by conciliation. If upon thyself being gratified, they agree to become friends, do thou, O king of kings, act in that way." These beneficial words having been said unto him by his friends, Duryodhana reflected for some time. Drawing deep breaths, he then, with a cheerless heart, said, "It is as thou, O friend, hast said. Listen, however, to the words that I would say unto thee. The wicked-hearted Vrikodara, having slain Duhshasana like a tiger, spoke words that still dwell in my heart.
