The Upanishads constitute the essence of the teachings from the Vedas, laying the foundation for the non-dualistic school of Advaita Vedanta.  In this book, Swami Jyotirmayananda brilliantly conveys the wisdom of four major Upanishadic texts – Kena, Mundaka, Prashna, and Ishavasya – in a concise and simple manner. The author’s translation and commentary of these ancient works enumerate for the spiritual seeker, in fine detail, the timeless truths realized through the spiritual revelations of the ancient sages and saints of India.
