The Upanishads rank with the greatest spiritual and philosophical writings of humanity. They have stood the test of time because of their beauty of expression and their depth of spiritual insight. The yoga of the Upanishads involves the whole person, not merely the physical body. It involves the union of the separate limited self with the higher eternal Self. The Upanishads are not based on speculation or scholastic debate, but upon actual experiences of illumined sages of ancient India. This lecture was delivered at the Theosophical Society in London and provides an excellent introduction to the Yoga of the Upanishads. 1972. 52 minutes.
