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.
Those who work at a thing heart and soul not only achieve success in it but through their absorption in that they also realize the supreme truth -- Brahman. Those who work at a thing with their whole heart receive help from God.
-Swami Vivekananda
