I think to want and try to understand images specifically ones created from within is akin to Ahab chasing the great white whale. One really can never understand and if you become obsessed with knowing or understanding it will likely end in disaster. Meatyard like many other artists and non-artists may not be looking for anything but rather atempting to articulate what they already know or feel. When you see your attemps eithen in a frame or as a poem, painting, etc you can't help but do it some more.
