Mbh 11.8.2a

"Vyasa said, 'O mighty-armed Dhritarashtra, listen to what I say. Thou art possessed of learning, thou hast great intelligence, and thou, O puissant one, art skilled in understanding duties. Nothing of that which should be known is unknown to thee, O scorcher of foes! Without doubt, thou knowest the instability of all things doomed to death. When the world of life is unstable, when this world itself is not eternal, when life is sure to end in death, why then, O Bharata, dost thou grieve? Before thy very eyes, O king, the concatenation of facts brought about by Time making thy son the cause, produced this hostility. This destruction of the Kurus, O king, was inevitable. Why then dost thou grieve for those heroes that have attained to the highest end? O thou of mighty arms, the high-souled Vidura knew everything. With all his might he had endeavoured, O king, to bring about peace. It is my opinion that the course marked out by Destiny cannot be controlled by anyone, even if one struggles for eternity. The course that was settled by the gods was heard directly by me. I will recite it to thee, so that tranquillity of mind may be thine. Once before, without any fatigue, I repaired very quickly to the court of Indra. There I beheld all the denizens of heaven assembled together. There were, O sinless one, all the celestial Rishis also, headed by Narada. There, O monarch, I saw also the Earth (in her embodied form). The latter had repaired to the gods for the accomplishment of a particular mission. Approaching the gods, she said, "That which ye all should do for me hath, ye blessed ones, been already promised by you while you were in Brahma's abode. Let that be accomplished soon." Hearing these words of hers, Vishnu, the adored of all the worlds, smilingly addressed her in the midst of the celestial conclave, saying, "The eldest of the hundred sons of Dhritarashtra, who is known by the name of Duryodhana, will accomplish thy business.
