Arcana Coelestia #12
12. The sixth state is when he utters truths and performs good deeds from faith and consequently from love. What he brings forth at this point are called a living creature and a beast. And because at this point he starts to act from faith and also simultaneously from love, he becomes a spiritual man, who is called an image. The spiritual life of that man finds its delight in, and is sustained by, the things which are associated with cognitions of faith and with charitable acts, which are called his food; and his natural life finds its delight in, and is sustained by, those which belong to the body and the senses. The latter give rise to conflict until love rules and he becomes a celestial man.
Heaven and Hell #126
126. Light and Warmth in Heaven
People who think solely on the basis of nature cannot grasp the fact that there is light in the heavens; yet in the heavens there is so much light that it is vastly greater than noonday light on earth. I have seen it often, even during our evenings and nights. At first I was amazed when I heard angels saying that our world's light was nothing but shadow in comparison to heaven's light, but now that I have seen it, I myself can bear witness. Its brightness and brilliance are beyond description. What I have seen in heaven I have seen in that light, and therefore more clearly and distinctly than what I have seen in this world.
