Śrī Caitanya Mahāprabhu said:

bhārata-bhūmite haila manuṣya-janma yāra janma sārthaka kari’ kara para-upakāra

As stated in this verse, Bhārata-varṣa is a most pious land. The followers of Vedic literature understand the Supreme Personality of Godhead in His different incarnations, and they are privileged to glorify the Lord by following the directions of Vedic literature. After realizing the glories of human life, such people should take up the mission to spread the importance of human life throughout the whole world. This is the mission of Śrī Caitanya Mahāprabhu. The word adhipuṇyam indicates that there are certainly many other pious men throughout the world but the people of Bhārata-varṣa are even more pious. Therefore they are fit to spread Kṛṣṇa Consciousness throughout the world for the benefit of all human society. Śrīla Madhvācārya also recognizes the land of Bhārata-varṣa: viśeṣād bhārate puṇyam. Throughout the world, there is no question of bhagavad-bhakti or devotional service, but the people of Bhārata-varṣa can easily understand the devotional service of the Lord. Thus every inhabitant of Bhārata-varṣa can perfect his life by discharging bhagavad-bhakti and then preaching this cult throughout the world for the benefit of everyone.
