Those who have joined this Krsna consciousness movement, my request is they follow the regulative principles, as instructed by Rupa Gosvami, with enthusiasm, read books and distribute books. And that is a very great service. I'll speak something, you may forget; but if you read from the book, you will get good opportunity to understand the philosophy. So our principle is to study the books as well as to distribute the books. People will be benefited, and their life will be successful. This is Krsna consciousness movement.
