Śrī Caitanya Mahāprabhu has clearly declared:

bhārata-bhūmite haila manuṣya-janma yāra
janma sārthaka kari’ kara para-upakāra
[Cc. Ādi 9.41]plugin-autotooltip__small plugin-autotooltip_bigŚrī Caitanya-caritāmṛta, Ādi-līlā 9.41

"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.

The real success or fulfillment of the mission of human life can be achieved in India, Bhārata-varṣa, because in Bhārata-varṣa the purpose of life and the method for achieving success are evident. People should take advantage of the opportunity afforded by Bhārata-varṣa, and this is especially so for those who are following the principles of varṇāśrama-dharma. If we do not take to the principles of varṇāśrama-dharma by accepting the four social orders (brāhmaṇa, kṣatriya, vaiśya and śūdra) and the four orders of spiritual life (brahmacārī, gṛhastha, vānaprastha and sannyāsa), there can be no question of success in life. Unfortunately, because of the influence of Kali-yuga, everything is now being lost. The inhabitants of Bhārata-varṣa are gradually becoming degraded mlecchas and yavanas. How then will they teach others? Therefore, this Kṛṣṇa consciousness movement has been started not only for the inhabitants of Bhārata-varṣa but for all the people of the world, as announced by Śrī Caitanya Mahāprabhu. There is still time, and if the inhabitants of Bhārata-varṣa take this movement of Kṛṣṇa consciousness seriously, the entire world will be saved from gliding down to a hellish condition. The Kṛṣṇa consciousness movement follows the process of pañcarātrika-vidhi and that of bhāgavata-vidhi simultaneously, so that people can take advantage of the movement and make their lives successful.
