When Sagara came to know that all his sons, whom he had sent in quest of the horse, had been destroyed by the might of the sage Kapila he sent Asamanja's son to bring the animal. Ansumat, proceeding by the path which Sagara's sons had dug, arrived where Kapila was and reverentially bowing unto him so pleased him that he said—"Go my son and gave over the horse to your grand father; ask of me a boon; thy grand-son shall bring down the river of heaven on earth". Ansumat begged of the glorious Rishi a boon that his uncles, who had died on account of his displeasure although unworthy of it, might be raised to heaven. The Rishi said—"I have told you that your grandson shall bring down the Ganges upon earth. When the ashes and bones Sagara's sons shall be washed by her waters they shall be raised to heaven. Such is the glory of the stream that issues from the toe of Vishnu that they all, who bathe in it intentionally or accidentally, go to heaven. Even those shall go to heaven whose bones, skin, fibres, hair or any other part shall be left after death upon the earth which is contiguous to the Ganges". Thereupon reverentially bowing unto the sage and taking the steed, he went where his grandfather was celebrating the sacrifice. On receiving back the horse Sagara completed the sacrifice and in memory of his sons he gave the name of Sagara to the chasm which they had dug.
