In the Bhagavad-gītā it is said: ye yathā māṁ prapadyante tāṁs tathaiva bhajāmy aham. There is a responsive cooperation between the Supreme Lord Kṛṣṇa and His devotees. The more a devotee sincerely loves Kṛṣṇa, the more Kṛṣṇa reciprocates, so much so that a highly advanced devotee can talk with Kṛṣṇa face to face. Kṛṣṇa confirms this in the Bhagavad-gītā (10.10):
dadāmi buddhi-yogaṁ taṁ
yena mām upayānti te
“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 Kṛṣṇa 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 Kṛṣṇa 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. Śrīmad-Bhāgavatam describes this as a form of cheating. Religion means abiding by the orders of Kṛṣṇa, 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 Kṛṣṇa consciousness are a useless waste of time.
