Eckhart Tolle is a spiritual teacher and author who was born in Germany and educated at the Universities of London and Cambridge. At the age of 29, 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.
