No matter what your notions of the reality of the experienced world it cannot be doubted that every feature and quality of that world belongs wholly to experience and its reality a projection from that experience, which also ultimately remains within experience. All these wonderful colours and shapes, these magnificent lures are, if you grant that mind is a product of the brain, entirely constructed within the brain. There is not even a question of what things in themselves 'look like', every kind of 'look' is a mind creation. If noticing this produces no jolt of unexpectedness, then see how the one noticing is itself something in the experienced world. To get to what is so startling you need to move the point from which you are seeing further back behind whatever is seen. It is not of the nature of a point, however, this seer, but closer to what you call space, pervading the context of your seeing, without any optics or geometry.
