"Vaisampayana said, 'O exalted one of Bharata's race, the founder of the Paurava line was Dushmanta gifted with great energy. And he was the protector of the earth bounded by the four seas. And that king had full sway over four quarters of this world. And he was the lord also of various regions in the midst of the sea. And that great oppressor of all foes had sway over the countries even of the Mlechchhas.
