This book consists of spiritual teachings and practices based on Vedanta. Equally useful for beginners as well as advanced aspirants, the book does shed shafts of light, dispelling the darkness of ignorance from the reader's heart. For a beginner, the book is a path-breaker; for an advanced aspirant, reassuring and strengthening; and for one already established in the goal, well, it should be a sheer delight. The book will benefit aspirants at any level, since it deals with Self-knowledge and the means to attain it.
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
