Tarkovsky on Art

So according to Tarkovsky, art does not equate with knowledge. Yet the artistic experience enriches one spiritually. So some sort of artistic residue remains, and accumulates, and he calls this spirit. What is the direction of this accumulation? What does it tend towards? A rising above oneself - an expression of "what we call 'free will.'"

I can say that Tarkovsky films play over in my mind for days after watching. Those long, disorienting shots, scrolling over some landscape close or far, have made me lose time more easily than any music. But that's not entirely true, since music and sound are indistinguishable elements from the whole of these scenes. And I am completely haunted by the way he lingers on inanimate objects, moments after all humans have left the scene. The thought of all the world happening at once, independent of any conscious perception, is one to behold. Surely the tree falls in the forest and makes a sound...?
