Matthew 6:22

22. Light of the body is the eye The body is as a large room, naturally dark, of which the inhabitant is the soul. But it has a light or lamp, the eye; for the eye gathers light from the external world of knowledge, and pours it, like a lamp, into the spacious residence of the soul. Eye be single Or pure from any foreign substance, duplicating and impeding its clear blaze. Body… light If the lamp give a pure light, the room is completely filled with illumination. When the moral perception is uninterfered with by any alloy of base self-interest, the soul possesses the pure light of truth.
