Mysteries of the mind second edition

I hope that the following explanations will serve for a better understanding of ourselves and what our real motives are the way we act think feel and why? The mind is an indivisible part of a human being. However to describe the mind I divided it artificially into various components as I do not know any better way to make the subject of the mind clear.
