"A Guide to Spiritual Enlightenment"

Eckhart Tolle took the mysticism out of Eastern philosophy and distilled its wisdom clearly and succinctly for a Western audience in search of answers. While subtitled "A Guide to Spiritual Enlightenment," The Power of Now (2004) really is a matter-of-fact road map for overcoming what's in your way to living a happy and fulfilled life: your mind.

When we first picked it up, we felt like we were reading stuff we had always known, just phrased better and more clearly. For those not familiar with basic Eastern philosophy principles such as the "eternal now," it will be a good intro to illustrate how thoughts of the past or future rob you of the current moment. And it's clear we're not alone. In 2008, some 35 million people participated in a series of live webinars with Tolle and Oprah Winfrey. Now that's some serious power!
