Upanisads are an authoritative compendium of Indian metaphysics. They represent the earnest efforts of profound thinkers of early India to solve the problems of origin, nature, and destiny of man and the universe, more technically the meaning and value of knowing and being. They are replete with sublime conceptions and with intuitions of universal truth. These Upanisads sets forth two opposing theories: one of mundane life and the other relating to a life that is in search of the Supreme Reality and man s ultimate aim. Though, traditionally, 108 Upanisads are well known and subject to various studies, there are around 200 Upanisads in toto. Of them, this volume contains the translation and interpretation of thirteen principal Upanisads such as Brhadaranyaka, Chandogya, Taittiriya, Aitareya, Kausitaki, Kena, Katha, Isa, Mundaka, Prasna, Mandukya, Svetasvatara and Maitri along with the outline of the philosophical wisdom inherent in these Upanisads. It also features the recurrent and parallel passages in these principal Upanisads and the Bhagavadgita.
