"Most of the thousands of letters and emails that have been sent to me from all over the world are from ordinary men and women, but there are also letters from Buddhist monks and Christian nuns, from people in prison or facing a life-threatening illness or imminent death. Psychotherapists have written to say that they recommend the book to their patients or incorporate the teachings in their practice. Many of those letters and emails mention a lessening or even a complete disappearance of suffering and problem-making in people's lives as a result of reading The Power of Now and putting the teachings into practice in everyday life. There is frequent mention of the amazing and beneficial effects of inner-body awareness, the sense of freedom that comes from letting go of self-identification with one's personal history and life-situation, and a newfound inner peace that arises as one learns to relinquish mental/emotional resistance to the "suchness" of the present moment."
Eckhart Tolle, Author's Preface to the Paperback Version of The Power of Now
