Modern psychology is fast discovering the truth explained in our scriptures that happiness and misery depend not upon one's material possessions but on the way one's mind responds to life's challenges. This book explains how the mind can be made our friend.
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
