In this episode, we take a simple, useful, and down-to-earth stroll through one of the most confounding -- but liberating -- concepts in Buddhism. On the one hand, Buddhists tell us the self is an illusion: “You don’t exist!” On the other hand, they tell us, “Well actually, on some level, you do, of course, exist.” So which is it? The answer is: both. But this concept -- call it not-self, selflessness, egolessness, or emptiness -- doesn’t have to be some hopelessly esoteric riddle; it is actually a game-changer that we can all apply in our own lives. Here to tell us how is Guy Armstrong, who has been a meditation teacher in the insight tradition for decades. He’s written a book called Emptiness: A Practical Guide for Meditators. He is the husband of Sally Armstrong, who appeared on the show just a few weeks ago. I actually conducted the interviews back-to-back last fall. But even though this was recorded before the wretched events of 2020, the concepts herein are, I assure you, perennially useful.
