The other day, I have read a book, which talked about something like spirit, soul, that kind of thing. It said that everyone has a "higher self " in themselves. Let say, this higher self is kinda like spirit, or soul or ghost, something that can float from the body,and observe the body, even the minds or thoughts. Suppose this is true, then My confusion comes from the ghosts in Harry Potter, the first one. remember that Duke Nearlyheadless -(-is this his name) in the film?
Look, if that "higher self, or spirit, or whatever(-- i am not sure at all), can float from the physical body, then any harm, dismantle to the physical body could not leave any scare on that "higher self", or ghost, whatever. How come the Duke nearlyheadless in Harry Potter can lift his head to show Hermione what is nearlyheadless like?
hope i have made myself clear.
What do you think? Any helpful explanation to me?? Thanks!
