Your internal map of reality, for those of you who are new to my writing, contains such things as your beliefs, values, internal strategies, ways you have of filtering information as it comes in, along with ways you have of sorting it, storing it, remembering, and retrieving it, as well as internal strategies for making decisions, along with the decisions themselves. All of these things operate unconsciously, outside our awareness, to create our experience of life. Since we don't choose how this map is structured (it pretty much happens to us as we grow up, as a result of all our experiences), it might give us the exact experience of life we want, but usually a fair amount--and in some people, a lot--of what it creates is what we don't want.
The process of becoming conscious of all of this material allows us to discover how we are creating what is happening in our lives, and to make conscious choices of how to do it in such a way that we create what we want, instead of whatever was planted in our minds by past experiences.
