“We should..distrust states of mind which turn our attention upon ourselves. Even at our sins we should look no longer than is necessary to know and repent of them: and our virtues or progress (if any) are certainly a dangerous object of contemplation.
When the sun is vertically above a man he casts no shadow: similarly when we have come to the Divine meridian our spiritual shadow (that is, our consciousness of self) will vanish. One will thus, in a sense, be almost nothing: a room to be filled by God and our blessed fellow creatures, who in their turn are rooms we help to fill. But how far one is from this at present!”

– CS Lewis from “God In The Dock”
