The sense organ which gives us an experience of sound, has its origins in the element space. The power to sense touch is connected with the element of air and the power to see is connected with fire. And yet what does the Upanishad say? Taitiri Upanishad. Where did these five elements come from? We'll eventually get to that also.
Swami Sarvapriyananda teaches the Katha Upanishad, one of India's most revered texts which is also a part of the Vedas. It is a collection of philosophical poems representing a conversation between the sage Naciketas and Yama (god of death). They discuss the nature of Atman, Brahman and Moksha(liberation).
