2.1.p5

The high-souled Nabhi, who had obtained the country of Nimahwa as his kingdom, had by his queen Meru, the highly effulgent son Rishabha; and who had again a hundred sons, the eldest of whom was Bharata. Having ruled over the kingdom piously and performed many sacrifices the illustrious Rishabha installed his eldest son Bharata as the lord of the earth and went to the hermitage of Pulastya, being bent upon practising religious penance according to the prescribed rites of an anchoret. He practised religious austerities duly until he was so reduced as to be but a collection of skin and fibres. Thereupon putting a pebble in his mouth he went naked to the great road. And from then the country was handed over to Bharata by his father on retiring to woods and it was called Bhārata.
