Mbh 1.62.2

“Janamejaya said, ‘O excellent Brahmana, thou hast, indeed, told me, in brief, the history, called Mahabharata, of the great acts of the Kurus. But, O thou of ascetic wealth, recite now that wonderful narration fully. I feel a great curiosity to hear it. It behoveth thee to recite it, therefore, in full. I am not satisfied with hearing in a nutshell the great history. That could never have been a trifling cause for which the virtuous ones could slay those whom they should not have slain, and for which they are yet applauded by men. Why also did those tigers among men, innocent and capable of avenging themselves upon their enemies, calmly suffer the persecution of the wicked Kurus? Why also, O best of Brahmanas, did Bhima of mighty arms and of the strength of ten thousand elephants, control his anger, though wronged? Why also did the chaste Krishna, the daughter of Drupada, wronged by those wretches and able to burn them, not burn the sons of Dhritarashtra with her wrathful eyes? Why also did the two other sons of Pritha (Bhima and Arjuna) and the two sons of Madri (Nakula and Sahadeva), themselves injured by the wretched Kurus, follow Yudhishthira who was greatly addicted to the evil habit of gambling? Why also did Yudhishthira, that foremost of all virtuous men, the son of Dharma himself, fully acquainted with all duties, suffer that excess of affliction? Why also did the Pandava Dhananjaya, having Krishna for his charioteer, who by his arrows sent to the other world that dauntless host of fighting men (suffer such persecution)? O thou of ascetic wealth, speak to me of all these as they took place, and everything that those mighty charioteers achieved.’
