There is no dualism in the world of light. The conventions of relativity say that time slows down as one approaches the speed of light, but if one tries to imagine the point of view of a thing made of light, one must realize that what is never mentioned is that if one moves at the speed of light there is no time whatsoever... One exists in eternity, one has become eternal... One is then apart from the moving image; one exists in the completion of eternity.
