2.3.1

śrīparāśara uvāca
uttaraṃ yatsamudrasya himādreścaiva dakṣiṇam /
varṣaṃ tadbhārataṃ nāma bhāratī yatra santatiḥ //

THE country that lies north of the ocean, and south of the snowy mountains, is called Bhárata, for there dwelt the descendants of Bharata. It is nine thousand leagues in extent, and is the land of works, in consequence of which men go to heaven, or obtain emancipation.
