What I have introduced into your Western countries, the pure love for Godhead process of Lord Caitanya Mahaprabhu, will go on increasing more and more to have effect by saving others; otherwise, it will gradually become mechanical and fade away like every other so-called religious movement. So you can understand that I am very much depending on you to become very much convinced yourself of our Krishna philosophy and to take full responsibility for teaching others purely.
Letter to Ranadhira, 17 January, 1972
