Ekhart Tolle's The Power of Now is a meditative approach to spiritual enlightenment — teaching the practice of living fully in the present and releasing from the mind to move past pain, stress and anxiety. Through ancient teachings and alternative, modern thought comes insight into presence, mindfulness, inner-peace and acceptance. It's a great prequel to A New Earth, where Tolle expands on these ideas to show how transcending our ego-based state of consciousness can lead to a fulfilling existence and better world.
