127. The light of heaven is not a natural light, like the light of the world, but a spiritual light, because it is from the Lord as a sun, and that sun is the Divine love (as has been shown in the foregoing chapter). That which goes forth from the Lord as a sun is called in the heavens Divine truth, but in its essence it is Divine good united to Divine truth. From this the angels have light and heat, light from Divine truth, and heat from Divine good. As the light of heaven, and the heat also, are from such a source, it is evident that they are spiritual and not natural.#
# All light in the heavens is from the Lord as a sun (n. 1053, 1521, 3195, 3341, 3636, 3643, 4415, 9548, 9684, 10809).
The Divine truth that goes forth from the Lord appears in heaven as light, and furnishes all the light of heaven (n. 3195, 3222, 3223, 5400, 8644, 9399, 9548, 9684).
