Srimad-Bhagavatam: Canto 5 - Chapter 1 - Verse 9

Sanskrit:

येषां खलु महायोगी भरतो ज्येष्ठ: श्रेष्ठगुण आसीद्येनेदं वर्षं भारतमिति व्यपदिशन्ति ॥ ९ ॥

ITRANS:

yeṣāṁ khalu mahā-yogī bharato jyeṣṭhaḥ śreṣṭha-guṇa āsīd yenedaṁ varṣaṁ bhāratam iti vyapadiśanti.

Translation:

Of Ṛṣabhadeva’s one hundred sons, the eldest, named Bharata, was a great, exalted devotee qualified with the best attributes. In his honor, this planet has become known as Bhārata-varṣa.

Purport:

This planet known as Bhārata-varṣa is also called puṇya-bhūmi, the pious land. At the present moment Bhārata-bhūmi, or Bhārata-varṣa, is a small piece of land extending from the Himālaya Mountains to Cape Comorin. Sometimes this peninsula is called puṇya-bhūmi. Śrī Caitanya Mahāprabhu has given special importance to the people of this land. “One who has taken his birth as a human being in the land of India (Bhārata-varṣa) should make his life successful and work for the benefit of all other people.” (Cc. Ādi 9.41) The inhabitants of this piece of land are very fortunate. They can purify their existence by accepting this Kṛṣṇa consciousness movement and go outside Bhārata-bhūmi (India) and preach this cult to benefit the whole world.
