They became his bards and panegyrists. Gratified, Prithu, the royal son of Vena, possessed of great prowess, gave unto Suta the land lying on the sea-coast, and unto Magadha the country since known as Magadha. We have heard that the surface of the earth had before been very uneven. It was Prithu who made the terrestrial surface level. In every Manwantara, the earth becomes uneven.[174] Vena's son removed the rocks and rocky masses lying all around, O monarch, with the horn of his bow. By this means the hills and mountains became enlarged. Then Vishnu, and the deities of Indra, and the Rishis, and the Regents of the world, and the Brahmanas, assembled together for crowning Prithu (as the king of the world). The earth herself, O son of Pandu, in her embodied form, came to him, with a tribute of gems and jewels. Ocean, that lord of rivers, and Himavat, the king of mountains, and Sakra, O Yudhishthira, bestowed upon him inexhaustible wealth. The great Meru, that mountain of gold, gave unto him heaps of that precious metal. The divine Kuvera, borne on the shoulders of human beings, that lord of Yakshas and Rakshasas, gave him wealth enough for gratifying the needs of religion, profit, and pleasure. Steeds, cars, elephants, and men, by millions, O son of Pandu, started into life as soon as Vena's son thought of them. At that time there was neither decrepitude, nor famine, nor calamity, nor disease (on earth). In consequence of the protection afforded by that king, nobody had any fear from reptiles and thieves or from any other source. When he proceeded to the sea, the waters used to be solidified. The mountains gave him way, and his standard was never obstructed anywhere. He drew from the earth, as a milcher from a cow, seven and ten kinds of crops for the food of Yakshas, and Rakshasas, and Nagas, and other creatures.
