The Autobiography in Five Chapters by Portia Nelson

The goal of buddhist philosophy isn't to take us to a set of revealed truths or facts. What it's trying to do is cause a radical shift in perspective. Stephen bachelor, in his book, buddhism without beliefs, says, to experience emptiness is to experience the shocking absence of what normally determines the sense of who you are and the kind of reality you inhabit. It may last only a moment before the habits of a lifetime reassert themselves and close in once again. But for that moment, we witness ourselves and the world as open and vulnerable.
