"Krishna is explaining Himself in the Bhagavad-gita, Krishna is sending His representative acarya to teach you, and Krishna is within yourself trying to teach you if you are actually serious. Then where is the difficulty? Inside, outside, always, books, knowledge -- He is prepared. So where is the difficulty to make yourself perfect in Krishna consciousness? There is no difficulty at all. Provided you are serious, you can become fully Krishna conscious in this very life. You are all young men. You are not old man like me. I have no opportunity."
