This book is a gem! Well-written and clearly organized, the book discusses the four yogas: jnana yoga, karma yoga, bhakti yoga and raja yoga and also has a concluding summary of them all. The author, one of the great early swamis of the Ramakrishna Order, was the first head of the Chicago Vedanta Society after Swami Vivekananda. Written with warmth, humor, intelligence and devotion, this book is a find.
