Yet his resolve to sever all connections with his former life remains and it is perhaps symbolic of his purpose that he now recalls the hunch-back girl, Kubja, takes Udho with him and in a single ecstatic visit becomes her lover. As he reaches her house, the girl greets him with delight, takes him inside and seats him on a couch of flowers. Udho stays outside and then while Krishna waits, the girl quickly bathes, scents herself, combs her hair and changes her dress. Then 'with gaiety and endearment' she approaches Krishna. Krishna, however, takes her by the hand and places her near him. Their passions rise and the two achieve the utmost bliss. Krishna then leaves her, rejoins Udho and 'blushing and smiling' returns home. The third step which Krishna must take is to deal with the political and military situation which has arisen from the slaying of the tyrant. We have seen how Kansa, although actually begotten by a demon was officially a son of Ugrasena, the king of Mathura, and as one of his many demon acts, had dethroned his father and seized the kingdom for himself. Ugrasena is still alive and the obvious course, therefore, is to reinstate him on the throne. Ugrasena, however, is unwilling to assume power and he and the other Yadavas implore Krishna to accept the title for himself. Krishna, however, has no desire to become king. He therefore overcomes Ugrasena's hesitations and in due course the latter is enthroned. This settles the succession problem, but almost immediately a graver issue arises. During his reign of terror, Kansa had made war on Jarasandha, king of Magadha. He had defeated him but as part of the peace terms had taken two of his daughters as queens. These have now been widowed by his death and repairing to their father's court, they rail bitterly against Krishna and beg their father to avenge their husband's death. Jarasandha, although a former rival of Kansa, is also a demon and can therefore summon to his aid a number of demon allies. Great armies are accordingly mobilized. Mathura is surrounded and the Yadavas are in dire peril. Krishna and Balarama, however, are undismayed. They attack the foes single-handed and by dint of their supernatural powers, utterly rout them. Jarasandha is captured but released so that he may return to the attack and even more demons may then be slaughtered. He returns in all seventeen times, is vanquished on each occasion but returns once more. This time he is aided by another demon, Kalayavana, and seeing the constant strain of such attacks, Krishna decides to evacuate the Yadavas and settle them at a new base. He commissions the divine architect, Visvakarma, to build a new city in the sea. This is done in one night, the city is called Dwarka[35] and there the Yadavas with all their goods are transported. When this has been done, Krishna and Balarama trick the demons. They pretend to be utterly defeated, retreat from Mathura and in despair ascend a tall hill. The
