pūrostu pauravo vaṃśo yatra jāto'si pārthiva |
idaṃ varṣasahasrāya rājyaṃ kārayituṃ vaśī || 27 ||

"The sons of Yadu are known by the name of the Yadavas: while those of Turvasu have come to be called the Yavanas. And the sons of Drahyu are the Bhojas, while those of Anu, the Mlechchhas. The progeny of Puru, however, are the Pauravas, amongst whom, O monarch, thou art born, in order to rule for a thousand years with thy passions under complete control.'"
