Vedic Upanishads are India's most ancient treasure of knowledge. They reveal the fundamental values as well as the ultimate goal of human life. Though forming part of the Vedic religious dissertations, the Upanishads discuss and reveal only pure wisdom, to be accessed by mind and intelligence. They deal alike with intricacies of human personality and world constitution. Shri Ram Piparaiya has evidently made a deep study in this area, and has brought together in one volume a useful compendium of original Upanishadic texts and commentaries.
