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.
Arcana Coelestia #1529
1529. It is very well known in heaven, but not so well known in the world of spirits, where so great a light comes from, namely from the Lord. And what is astonishing, the Lord appears to celestial angels in the third heaven as the Sun, but to spiritual angels as the Moon. There is no other source of light. But the intensity of the light angels experience depends on how celestial and spiritual they are, and the nature of the light depends on the nature of these qualities. Thus the Lord's celestial and spiritual itself shows itself before angels' external vision by means of the light.
