Eckhart Tolle, is a German-born resident of Canada, best known as the author of The Power of Now and A New Earth. In 2011, he was listed by the Watkins Review as the most spiritually influential person in the world. In 2008, a New York Times writer called Tolle "the most popular spiritual author in the United States". Tolle has said that he was depressed for much of his life until he underwent, at age 29, an "inner transformation". He then spent several years wandering and unemployed "in a state of deep bliss" before becoming a spiritual teacher. Later, he moved to North America where he began writing his first book, The Power of Now, which was published in 1997 and reached the New York Times Best Seller lists in 2000. Tolle settled in Vancouver, Canada, where he has lived for more than a decade.
