Mysticism is the birthright of every human being, says Br. David Steindl-Rast. He speaks of the anatomy and practice of gratitude as full-blooded, reality-based, and redeeming. Now in his 90s, he has lived through a world war, the end of an empire, and the fascist takeover of his country. He was an early pioneer, together with Thomas Merton, of dialogue between Christian and Buddhist monastics. He’s also given a TED talk, viewed over six million times, on the subject of gratitude — a practice increasingly interrogated by scientists and physicians as a key to human well-being.This interview is edited and produced with music and other features in the On Being episode “David Steindl-Rast — Anatomy of Gratitude.” Find more at onbeing.org.
