"Only by devotional service is the Supreme Truth, Krishna, pleased, and by His inconceivable energy He can reveal Himself to the heart of the pure devotee. The pure devotee always has Krishna within his heart; therefore he is just like the sun that dissipates the darkness of ignorance. This is the special mercy rendered to the pure devotee by Krishna."
(Bhagavad-gita As It Is 10.11, Purport)
