Asamanjas was from his boyhood of very irregular conduct. His father hoped that as he grew up to manhood he would reform; but finding that he continued guilty of the same immorality, Sagara abandoned him. The sixty thousand sons of Sagara followed the example of their brother Asamanjas. The path of virtue and piety being obstructed in the world by the sons of Sagara, the gods repaired to the Muni Kapila, who was a portion of Vishńu, free from fault, and endowed with all true wisdom. Having approached him with respect, they said, "O lord, what will become of the world, if these sons of Sagara are permitted to go on in the evil ways which they have learned from Asamanjas! Do thou, then, assume a visible form, for the protection of the afflicted universe." "Be satisfied," replied the sage, "in a brief time the sons of Sagara shall be all destroyed."
