2.1.31

tapasā karṣitotyarthaṃ kṛśo dhamanisantataḥ /
nagno vīṭāṃ mukhe kṛtvā vīrādhvānaṃ tato gataḥ //

Nábhi, who had for his portion the country of Himáhwa, had by his queen Meru the magnanimous Rishabha; and he had a hundred sons, the eldest of whom was Bharata. Rishabha having ruled with equity and wisdom, and celebrated many sacrificial rites, resigned the sovereignty of the earth to the heroic Bharata, and, retiring to the hermitage of Pulastya, adopted the life of an anchoret, practising religious penance, and performing all prescribed ceremonies, until, emaciated by his austerities, so as to be but a collection of skin and fibres, he put a pebble in his mouth, and naked went the way of all flesh. The country was termed Bhárata from the time that it was relinquished to Bharata by his father, on his retiring to the woods.
