The Power of Now: A Guide to Spiritual Enlightenment, Eckhart Tolle, 2004 

Tolle’s signature book about finding inner peace and Being through renouncing the egoic mind which depends on the past and future, i.e. time and the embrace of the Now.  Awareness and acceptance lead to the loss of the pain of our past, a pain that determines our view of ourselves and our need for power and position.  This awareness enables us to be present in each moment, accept it for what it is, and achieve the inner peace that comes with that acceptance.  Lose resistance and gain peace through becoming in touch with the Now through meditation.  Tuning into the breath and the body enables one to screen out the ever present running commentary of thought that is the mind that depends on our view of the past and our worry about the future.  Anxiety, fear, depression, paranoia are all the result of this mind-pain.  Stepping outside ourselves to be the observer of our situation enables one to recognize, analyze, be aware, and accept the present moment and ourselves.  Acceptance leads to peace and growth.  A bit too New Age but full of useful observations and advice.
