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.
Seek ye first the kingdom of God, and everything shall be added unto you. This is the one great duty, this is renunciation. Live for an ideal, and leave no place in the mind for anything else. Let us put forth all our energies to acquire that which never fails--our spiritual perfection. If we have true yearning for realization, we must struggle, and through struggle growth will come. We shall make mistakes, but they may be angels unawares.
-Swami Vivekananda
