Myth, the Universe, and Everything

I've been thinking about this comment more and more, even after leaving a response on facebook, and I wonder if the idea of that "true" personality is tied into the idea of the soul -- at least, in how I thought about such things as I was growing up. It goes with that body-mind-spirit division that we hear about so often: the idea seems to be that those elements aren't already unified -- that somehow, they're divorced from each other. I had in my head that the soul was something housed by the body, but independent -- the objective self, if you will. And I'm wondering how much I need to entire reevaluate that way of thinking -- that there isn't an objective self beyond the body, there's the self that is part of the body.
