20 of today's most spiritually influential individuals

German-born spiritualist and teacher Eckhart Tolle was listed by the Watkins Review as the most spiritually influential person in the world for his popular teachings on finding true, lasting inner peace outside of God. Sometimes denigrated by religious leaders for his New Age thinking and serenity-focused lifestyle teachings, Tolle's books, videos, webinars and speaking engagements focused on the idea of letting go of "self" have made his name famous world-wide.
