This little book is an attempt to answer some of the typical questions posed by students as well as critics. These answers help remove misconceptions by offering explanations indicative of the origin of familiar ideas and institutions.
Take up one idea. Make that one idea your life -- think of it, dream of it, live on that idea. Let the brain, muscles, nerves, every part of your body, be full of that idea, and just leave every other idea alone. This is the way to success, and this is the way great spiritual giants are produced. Others are mere talking machines.
-Swami Vivekananda
