Do you know there's a wonderful Christian idea in which Thomas stretches his hands out to try to touch Christ's wound and Christ says 'Noli me tangere' (do not touch me). What your eyes see your hands will always try to affirm. Much of dealing with the non-material is about this confusion between the hand and the eye, the ear and the eye, when the thing that you look at is uncertain, your body demands a kind of readjustment, it demands certainty. Something happens to where you are, to space; time changes. Time, I think, becomes slower. The mystical truth of art is time.
