A bunch of above posts have to do with where the self ends. I don't think the "self" is something that you can define that way, it's the consequence of a large scale system of complex interactions with thousands of still misunderstood variables. The human body isn't the self, if you removed the head from the body but maintained blood and oxygen and nutrient flow to the head it would survive, and the self would continue. So did the self just get much smaller? The boundary between the human body and the air, or one body and another boundary, isn't that well defined when you get to a quantum level. If you went to space you might argue the boundary is more defined, but when do you stop defining the heat energy you produce? And how do you differentiate between your body and the radiation passing through it, does it become a part of your body? "I think, therefore I am". Both of the two main contributors to this part of the thread need to stop bickering and focus on some actual questions.
My religion is the understanding of my world. My god is the energy that underlies it all. My worship is my constant endeavor to unravel the mysteries of my religion.
