The Power of Now by Eckhart Tolle (2004, Paperback, Reprint)

The Power of Now (TPON) has the power to fundamentally and profoundly change your life if read with an open mind (or "no-mind" - inside joke). It gives you a radically different perspective on life and teaches you to find peace within, no matter your outer circumstances. Some may find the reading a bit difficult at first, but keep with it and all will become clear as the author's concepts become easier to understand. Don't let the subtitle "a guide to spiritual transformation" scare you off...Tolle writes from a non-denominational viewpoint and his insights are more psychological than religious, although you will likely want to explore your spiritual side more deeply once you read TPON. His concepts are strongly influenced by Zen Buddhism, but you wouldn't know that unless you've already studied Zen. I like how he explains some of Christianity's confusing concepts with clear interpretations of Jesus' teachings. But the overall concept is in becoming truly "aware/conscious" in the present, and letting go of neurotic mind-patterns: very simple, but not easy. TPON will give you practical ways to practice this. It's a bit repetitive, but sometimes re-stating the same concept in a different way will reach different readers more clearly. It only serves to drive home the book's excellent principles. Highly recommended for anyone on a spiritual path as well as those just wanting a happier, more peaceful and loving life.
