God is the Light1 of the heavens and the earth.2 The Parable of His Light is as if there were a Niche and within it a Lamp: the Lamp enclosed in Glass:3 the glass as it were a brilliant star:4 Lit from a blessed Tree,5 an Olive, neither of the east nor of the West,6 whose oil is well-nigh luminous, though fire scarce touched it:7 Light upon Light! God doth guide whom He will to His Light:8 God doth set forth Parables for men: and God doth know all things.
