What makes a mere happening into experience, gives it its felt quality, something that it feels like, is the background, the backdrop, as it were, against which what appears appears. This background changes radically, but changes are barely noticed because you cannot directly attend to the background, you know it without knowing it. Nonetheless, all changes in consciousness are changes in the background, from near to far, from tight to wide, changes in which nothing actually moves or is modified in any way.
