Vasishtha, making them deprived of their power, although living, thus said to Sagara—"O my child, these, are already dead. What is the use of pursuing them? To keep up your vow I have made them renounce their own religion and the company of twice-born ones". Sagara reverentially obeyed the request of his spiritual guide and imposed upon them peculiar distinguishing marks. He made the Yavanas shave their heads entirely and the Sakas partially. The Paradas wore their long hair and the Pahnavas allowed their beards to grow according to his command. He withdrew from these and other Kshatriya races the privilege of offering oblations to fire and studying the Vedas. And being thus deprived from the performance of religious rites and having been abandoned by the Brāhmins they all became Mlechasas. Having thus recovered his kingdom Sagara ruled over the earth having seven continents with undisputed sway.
