"To let the cat out of the bag right at the beginning: The basic assumption underlying Far Eastern and East Indian cultures is that the whole cosmos, the whole universe, is one being. It is not a collection of many things that ?oated together like a lot of ?otsam and jetsam from the ends of space and just happened to end up forming this thing we call the universe. Easterners look at the world as one eternal activity, and that’s the only real self you have. You are the works, and that thing we call you, the so-called “separate organism,” is simply a manifestation of the whole thing. And this is not just a theory, it is a feeling that they have."
Alan Watts
