All doubts about the self cease. This is so vivid, so blazing forth. There can be no more doubt if you look up at the sun,. You cannot deny the existence of this tremendous light burning down at you. And in fact, there is no whole and part relationship there. There is only that one. That's our real nature. All these ino various theories, they come to a rest there. They're all transcended. There isn't any further debate possible."
Swami Sarvapriyananda teaches the Katha Upanishad, which is one of the most popular Upanishads. The scripture concerns the story of a young man who goes to the house of death to find out what happens after death. The reply describes the nature of reality and the meaning of life.
