Ajamíd́ha had a wife called Níliní, and by her he had a son named Níla; his son was Śánti; his son was Śuśánti; his son was Purujánu; his son was Chakshu; his son was Haryyaśwa, who had five sons, Mudgala, Śrinjaya, Vrihadishu, Pravíra, and Kámpilya. Their father said, "These my five (pancha) sons are able (alam) to protect the countries;" and hence they were termed the Pánchálas. From Mudgala descended the Maudgalya Brahmans: he had also a son named Bahwaśwa, who had two children, twins, a son and daughter, Divodása and Ahalyá. The son of Śaradwat or Gautama by Ahalyá was Śatánanda; his son was Satyadhriti, who was a proficient in military science. Being enamoured of the nymph Urvaśí, Satyadhriti was the parent of two children, a boy and a girl. Śántanu, a Raja, whilst hunting, found these children exposed in a clump of long Śara grass; and, compassionating their condition, took them, and brought them up. As they were nurtured through pity (kripá), they were called Kripa and Kripí. The latter became the wife of Drońa, and the mother of Aswattháman.
