The son of Kakutstha was Anenas, whose son was Prithu, whose son was Viswagaśwa, whose son was Árdra, whose son was Yuvanáśwa, whose son was Śravasta, by whom the city of Śrávastí was founded. The son of Śravasta was Vrihadaśwa, whose son was Kuvalayáśwa. This prince, inspired with the spirit of Vishńu, destroyed the Asura Dhundhu, who had harassed the pious sage Uttanka; and he was thence entitled Dhundhumára. In his conflict with the demon the king was attended by his sons, to the number of twenty-one thousand; and all these, with the exception of only three, perished in the engagement, consumed by the fiery breath of Dhundhu. The three who survived were Drídháśwa, Chandráśwa, and Kapiláśwa; and the son and successor of the elder of these was Haryyáśwa; his son was Nikumbha; his son was Sanhatáśwa; his son was Kriśáśwa; his son was Prasenajit; and his son was another Yuvanáśwa.
