The Power of Now: A Guide to Spiritual Enlightenment - Eckhart Tolle I've read almost all the books mentioned in it, I've study oriental-philosophy and practised it, yet this book gets to explain it all together and how it is all the same thing and every knowledge is connected. It is a very dense book, its topic is too difficult to explain with words and until now, this is the only book that gets to put it as simple as I think it can be put using language.
