You are very intelligent and nice boy and girl, and trying to understand Krishna Consciousness, and I can simply pray that you shall try to understand more and more about this transcendental science, and whenever possible, try to talk about Krishna Consciousness to your friends or whomever you may meet. Simply by this attempt you will get superior strength and knowledge about Krishna Consciousness. It doesn't matter whether a man is convinced or not, but your sincere attempts to convince others will help you progress. Nandarani is very intelligent girl, both of you execute nicely and try to bring up your daughter in the same spirit, and live nicely in Krishna Consciousness.
Letter to Nandarani and Dayananda, 29 April, 1968
