The author had quoted from this Upanishad and explained its ideas in several of his lectures, class-talks, and conversations. All this material, spread throughout the nine volumes of his Complete Works, has been brought together in this book for the first time. What makes this compilation a treasure trove of original ideas and masterly insights is that the author goes straight to the heart of the subject to focus on the essentials, and to evolve practical methods from abstract principles.
No one should be judged by their defects. The great virtues a person has are his or her especially. But their errors are the common weakness of humanity and should never be counted in estimating a person's character.
-Swami Vivekananda
