The fact that all we will ever have is the present moment is liberating. It's a fantastic read and it certainly borrows from many teachings/disciplines including Buddhism/zen. I'm going to start listening again while running.
That is pretty much the underlining of all Buddhist disciplines. Tolle makes it very western friendly, but it's the truth. You have now, or you have nothing. You live for the future, you throw away today. You worry about yesterday, you throw away today. And on and on. The past is the past and the future is uncertain, and the future will be awesome as long as you're productive in the now. I loved that book. I read a lot of "self help" books before landing on Buddhism/Zen, but the ideas Tolle presents are near identical.The fact that all we will ever have is the present moment is liberating.
