You have invented words like effort, inner, outer, self, etc. and seek to impose them on reality. Things just happen to be as they are, but we want to build them into a pattern, laid down by the structure of our language. So strong is this habit, that we tend to deny reality to what cannot be verbalised. We just refuse to see that words are mere symbols, related by convention and habit to repeated experiences.
