It is these beliefs which govern the _Mahabharata_ epic and provide the clue to Krishna's role. Its prime subject is a feud between two families, a feud which racks and finally destroys them. At the same time, it is very much more. Prior to the events narrated in the text, Vishnu has already undergone seven incarnations, taking the forms of a fish, tortoise, boar and man-lion and later those of Vamana the dwarf, Parasurama ('Rama with the Axe'), and finally, the princely Rama. In each of these incarnations he has intervened and, for the time being, rectified the balance. During the period covered by the epic, he undergoes an eighth incarnation and it is in connection with this supremely vital intervention that Krishna appears. To understand the character which now unfolds, we must briefly consider the central story of the _Mahabharata_. This is narrated in the most baffling and stupendous detail. Cumbrous names confront us on every side while digressions and sub-plots add to the general atmosphere of confusion and complexity. It is idle to hope that this vast panorama can arouse great interest in the West and even in India it is unlikely that many would now approach its gigantic recital with premonitions of delight. It is rather as a necessary background that its main outlines must be grasped, for without them Krishna's character and career can hardly be explained. The epic begins with two rival families each possessed of a common ancestor, Kuru, but standing in bitter rivalry to each other. Kuru is succeeded by his second son, Pandu, and later by Dhritarashtra, his first son but blind. Pandu has five sons, who are called Pandavas after him, while Dhritarashtra has a hundred sons called Kauravas after Kuru, their common grandfather. As children the two families grow up at the same court, but almost immediately jealousies arise which are to have a deadly outcome. Hatred begins when in boyish contests the Pandavas outdo the Kauravas. The latter resent their arrogance and presently their father, the blind king, is persuaded to approve a plot by which the five Pandavas will be killed. They are to sleep in a house which during the night will be burnt down. The plot, however, miscarries. The house is burnt, but unbeknown to the Kauravas, the five brothers escape and taking with them their mother, Kunti, go for safety to the forest. Here they wander for a while disguised as Brahmans or priests but reach at last the kingdom of Panchala. The King of Panchala has a daughter, Draupadi, whose husband is to be chosen by a public archery competition. Arjuna, one of the five brothers, wins the contest and gains her as bride. The Pandavas, however, are polyandrous and thus, on being married to one brother, Draupadi is also married to the other four. At the wedding the Pandavas disclose their identities. The Kauravas learn that they are still alive and in due course are reconciled. They reinstate the Pandavas and give them half the kingdom.
