Before Arjuna, however, can profit from the truce, he infringes by accident his elder brother's privacy by stumbling on him while he is with their common wife. As a consequence he violates a standing agreement and has no alternative but to go into exile for twelve years. Arjuna leaves the court, visits other lands, acquires a new wife and makes a new alliance. In other respects, all is well and the two families look forward to many years of peaceful co-existence. The fates, however, seem determined on their destruction. The leader of the Pandavas is their eldest brother, Yudhisthira. He conquers many other lands and is encouraged to claim the title, 'ruler of the world.' The claim is made at a great sacrifice accompanied by a feast. The claim incenses the Kauravas and once again the ancient feud revives. Themselves expert gamblers, they challenge Yudhisthira to a contest by dice. Yudhisthira stupidly agrees and wagering first his kingdom, then his brothers and finally his wife, loses all and goes again into exile. With him go the other Pandavas, including Arjuna who has since returned. For twelve years they roam the forests, brooding on their fate and planning revenge. When their exile ends, they at once declare war. Both sides seek allies, efforts at peacemaking are foiled and the two clash on the battle-field of Kurukshetra. For eighteen days the battle rages till finally the Pandavas are victorious. Their success, however, is at an appalling cost. During the contest all five Pandavas lose their sons. The hundred sons of their rival, the blind king Dhritarashtra, are dead and with a sense of tragic futility, the epic ends.
