The great Rishis, assembling together in the great forest, installed him in the sovereignty of the earth. And because it was thought that he would advance all mankind, he was, for that reason, called Prithu (the advancer). And because also he protected people from injuries (Kshata), he was, for that reason, called a Kshatriya (protector from injuries). Beholding Prithu the son of Vena, all the creatures of the earth exclaimed, 'We have been lovingly attached to him.' From this circumstance of the loving attachment (to him of all creatures), he came to be called a Raja (one that can inspire attachment). The earth, during his sway, yielded crops without being tilled, every leaf that the trees had bore honey; and every cow yielded a jugful of milk. All men were hale and all their wishes used to be crowned with fruition. They had no fear of any kind. They used to live, as they pleased, in fields or in (sheltered) houses. When Prithu desired to go over the sea, the waters became solidified. The rivers also never swelled up when he had to cross them but remained perfectly calm. The standard on his car moved freely everywhere (without being obstructed by any impediment). King Prithu, in one of his grand Horse-sacrifices, gave away unto the Brahman as one and twenty mountains of gold, each measuring three nalwas. When he, O Srinjaya, who far surpassed thee in the four principal attributes and who was purer than thy son, fell a prey to death, do not grieve for thy son that is dead.
