His life work has been largely dedicated to bringing mindfulness into the mainstream of medicine and society. Kabat-Zinn is the author or co-author of scientific papers on mindfulness and its clinical applications. He has written two bestselling books: Full Catastrophe Living: Using the Wisdom of Your Body and Mind to Face Stress, Pain and Illness (Delta, 1991), and Wherever You Go, There You Are: Mindfulness Meditation in Everyday Life (Hyperion, 1994). He co-authored with Myla Kabat-Zinn Everyday Blessings: The Inner Work of Mindful Parenting, (Hyperion, 1997). Other books include Coming to Our Senses (Hyperion, 2005) and his most recent book The Mindful Way Through Depression: Freeing Yourself from Chronic Unhappiness, co-authored with J. Mark G. Williams, John D. Teasdale and Zindel V. Segal (Guilford, 2007). Kabat-Zinn is the founder and former Executive Director of the Center for Mindfulness in Medicine, Health Care, and Society at the University of Massachusetts Medical School. He is also the founder (1979) and former director of its renowned Stress Reduction Clinic and Professor of Medicine emeritus at the University of Massachusetts Medical School. Kabat-Zinn received his Ph.D. in molecular biology in 1971 from MIT where he studied under Salvador Luria, Nobel Laureate in Medicine. Kabat-Zinn has made significant contributions to modern health care with his research which focused on mind/body interactions for healing, and on various clinical applications of mindfulness meditation training for people with chronic pain and/or stress-related disorders. Kabat-Zinn began teaching the Mindfulness-Based Stress Reduction (MBSR) at the Stress Reduction Clinic in 1979. MBSR is an eight week course which combines meditation and Hatha yoga to help patients cope with stress, pain, and illness by using moment-to-moment awareness. Such mindfulness helps participants use their inner resources to achieve good health and well being. Kabat-Zinn and colleagues have studied the effects of practicing moment-to-moment awareness on the brain, and how it processes emotions, particularly under stress, and on the immune system. He is a board member of the Mind and Life Institute, a group that organizes dialogues between the Dalai Lama and Western scientists to promote deeper understanding of different ways of knowing and probing the nature of mind, emotions, and reality.

Spiritual Teacher and author was born in Germany and educated at the Universities of London and Cambridge. At the age of twenty-nine a profound inner transformation radically changed the course of his life. The next few years were devoted to understanding, integrating and deepening that transformation, which marked the beginning of an intense inward journey. Later, he began to work in London with individuals and small groups as a counselor and spiritual teacher. Since 1995 he has lived in Vancouver, Canada. Eckhart Tolle is the author of the #1 New York Times bestseller The Power of Now (translated into 33 languages) and the highly acclaimed follow-up A New Earth, which are widely regarded as two of the most influential spiritual books of our time. Eckhart’s profound yet simple teachings have already helped countless people throughout the world find inner peace and greater fulfillment in their lives. At the core of the teachings lies the transformation of consciousness, a spiritual awakening that he sees as the next step in human evolution. An essential aspect of this awakening consists in transcending our ego-based state of consciousness. This is a prerequisite not only for personal happiness but also for the ending of violent conflict endemic on our planet. Eckhart is a sought-after public speaker and teaches and travels extensively throughout the world. Many of his talks, intensives and retreats are published on CD and DVD. Most of the teachings are given in English, but occasionally Eckhart also gives talks in German and Spanish. In addition to The Power of Now and A New Earth, Eckhart has written a book designed for meditative reading entitled Stillness Speaks. A book consisting of selections from The Power of Now is also available, entitled Practicing the Power of Now.
