I continue a conversation as Part 3 with guest Dr. Jon Kabat-Zinn, Ph.D., Professor of Medicine emeritus at the University of Massachusetts Medical School, where he founded its world-renowned Mindfulness-Based Stress Reduction (MBSR) Clinic in 1979. The program continues at the clinic, and now in clinics and community centers around the globe, 42 years later. Jon is the author of many well-known mindfulness meditation books, including Full Catastrophe Living, the classic Mindfulness-Based Stress Reduction (MBSR) manual, which is published in 10 languages. We discuss a 50-year career in mindfulness research and teaching, research findings on MBSR for skin disorders, and mindfulness as conceptualized in the past, present and future.
