And when the wielder of the thunderbolt said, 'He will suck me,' the dwellers of heaven together with Indra christened the boy Mandhata, (literally, Me he shall suck). Then the boy having tasted the forefinger extended by Indra, became possessed of mighty strength, and he grew thirteen cubits, O king. And O great king! the whole of sacred learning together with the holy science of arms, was acquired by that masterful boy, who gained all that knowledge by the simple and unassisted power of his thought. And all at once, the bow celebrated under the name of Ajagava and a number of shafts made of horn, together with an impenetrable coat of mail, came to his possession on the very same day, O scion of Bharata's race! And he was placed on the throne by Indra himself and he conquered the three worlds in a righteous way, as Vishnu did by his three strides. And the wheel of the car of that mighty king as irresistible in its course (throughout the world). And the gems, of their own accord, came into the possession of that saintly king. This is the tract of land, O lord of earth, which belonged to him. It abounds in wealth. He performed a number of sacrificial rites of various kinds, in which abundant gratuities were paid to the priests. O king! he of mighty force and unmeasured lustre, erected sacred piles, and performed splendid pious deeds, and attained the position of sitting at Indra's side.
