Art that has images in it that you can recognize is like a lot of words on a page. You understand it and can relate to the piece on a level that is talkable.
But totally abstract works are created on a different level. They are non wordable. They are like ink being dropped into clear water. the ink makes all the wordable aspects of the work opaque. You are left with the ink color which speaks to a different part of your brain, the place where dreams come from , where feelings come from, where devotion comes from.
Artists are people who are processing their own lives and then in turn help everyone else to process theirs too.
