Today i was contemplating distance, and had the insight that distance is actually a concept. The idea of "me being in here behind the eyes" is conceptual, thus the idea of "me here, wall there" must be conceptual, and therefor the idea of "distance between me and wall" must also be conceptual.
As I was contemplating this along with other aspects of mind like "inside the skull, emotions, sense of self, beliefs and thoughts" I began to wonder...Where does any of this actually exist? It can't be coming from inside my head or brain because even that notion is a concept that I am doing, so it must just be imagined out of pure nothingness "thin air" if you'd like.
Anyone come across this?
Cheers
