There are many facilities in India, Bharata-varsa, for executing devotional service. In Bharata-varsa, all the acaryas contributed their experience, and Sri Caitanya Mahaprabhu personally appeared to teach the people of Bharata-varsa how to progress in the spiritual life and be fixed in devotional service to the Lord. From all points of view, Bharata-varsa is the special land where one can very easily understand the process of devotional service and adopt it to make his life successful. If one makes his life successful in devotional service and then preaches devotional service in other parts of the world, people throughout the world will actually benefit.
bharata-bhumite haila manusya-janma yara
janma sarthaka kari’ kara para-upakara
“One who has taken his birth as a human being in the land of India [Bharata-varsa] should make his life successful and work for the benefit of all other people.”
The land of Bharata-varsa is so exalted that by taking birth there one can not only attain the heavenly planets but also go directly back home, back to Godhead. As Krishna says in Bhagavad-gita (9.25):
yanti deva-vrata devan pitrn yanti pitr-vratah
bhutani yanti bhutejya yanti mad-yajino ‘pi mam
“Those who worship the demigods will take birth among the demigods; those who worship ghosts and spirits will take birth among such beings; those who worship ancestors go to the ancestors; and those who worship Me will live with Me.” people in the land of Bharata-varsa generally follow the Vedic principles and consequently perform great sacrifices by which they can be elevated to the heavenly planets.
However, what is the use of such great attainments? As stated in Bhagavad-gita (9.21), ksine punye
martya-lokam visanti: after the results of one’s sacrifices, charity and other pious activities expire, one must return to the lower planetary systems and again feel the pangs of birth and death. However, one who becomes Krishna conscious can go back to Krishna (yanti-mad-yajino ‘pi mam). Therefore the demigods even regret having been elevated to the higher planetary systems. The denizens of the heavenly planets regret that they could not take full advantage of being born in the land of Bharata-varsa. Instead, they became captivated by a higher standard of sense gratification, and therefore they forgot the lotus feet of Lord Narayana at the time of death. The conclusion is that one who has taken birth in the land of Bharata-varsa must follow the instructions given personally by the Supreme Personality of Godhead. Yad gatva na nivartante tad dhama paramam mama. One should try to return home, back to Godhead, to the Vaikuntha planets–or to the topmost Vaikuntha planet, Goloka Vrindavana–to live eternally in full, blissful knowledge in the company of the Supreme Personality of Godhead.
