In the Bhagavad-gita it is said: ye yatha mam prapadyante tams tathaiva bhajamy aham. There is a responsive cooperation between the Supreme Lord Krsna and His devotees. The more a devotee sincerely loves Krsna, the more Krsna reciprocates, so much so that a highly advanced devotee can talk with Krsna face to face. Krsna confirms this in the Bhagavad-gita (10.10):

"To those who are constantly devoted to worshiping Me with love, I give the understanding by which they can come to Me." The actual mission of human life is to understand Krsna and return home, back to Godhead. Therefore one who is sincerely engaged in the service of the Lord with love and faith can talk with Krsna and receive instructions by which he can speedily return home, back to Godhead. Today many scholars defend the science of religion, and they have some conception of the Supreme Personality of Godhead, but religion without practical experience of the Supreme Personality of Godhead is no religion at all. Srimad-Bhagavatam describes this as a form of cheating. Religion means abiding by the orders of Krsna, the Supreme Personality of Godhead. If one is not qualified to talk with Him and take lessons from Him, how can one understand the principles of religion? Thus talks of religion or religious experience without Krsna consciousness are a useless waste of time.
