The real success or fulfillment of the mission of human life can be achieved in India, Bharata-varsa because in Bharata-varsa the purpose of life and the method for achieving success are evident. People should take advantage of the opportunity afforded by Bharata-varsa, and this is especially so for those who are following the principles of varnasrama-dharma. If we do not take to the principles of varnasramadharma by accepting the four social orders (brahmana, ksatriya, vaisya, and sudra) and the four orders of spiritual life (brahmacari, grhastha, vanaprastha, and sannyasa), 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 Bharata-varsa are gradually becoming degraded mlecchas and yavanas. How then will they teach others? Therefore, this Krishna consciousness movement has been started not only for the inhabitants of Bharatavarsa but for all the people of the world, as announced by Sri Caitanya Mahaprabhu. There is still time, and if the inhabitants of Bharata-varsa take this movement of Krishna consciousness seriously, the entire world will be saved from gliding down to a hellish condition. The Krishna consciousness movement follows the process of pancaratrika-vidhi and that of bhagavata-vidhi simultaneously, so that people can take advantage of the movement and make their lives successful.
