The Power of Now written by Ekhart Tolle is heavy to digest book. Main theme of the book is living in the now is the truest path to happiness and enlightenment. It is a well written book and can be read in 15 days max. Best part are question and answers in every chapter in which you feel author is reading your ming and answering all your doubts which you may have.
Tolle suggest that we have the power to focus on this very moment, as it is the only one we really have. The past is past and the future is not here, and may not ever come. I would recommend this to anyone who like philosophical reading and implementing it in their own life. Check out book at by clicking here.
