3636. This is a most universal truth: That the Lord is the Sun of heaven, and that from this Sun is all the light in the other life; and that to angels and spirits, or those who are in the other life, nothing at all of the light of the world appears; and also that the light of the world, which is from its sun, is only thick darkness to angels. From the Sun of heaven, or from the Lord, there is not only light, but also heat; but it is spiritual light and spiritual heat. To the angels’ eyes this light appears as light, but has within it intelligence and wisdom, because this is its source; and by their senses this heat is perceived as heat, but there is within it love, because this is its source. For this reason love is also called spiritual heat, and likewise constitutes the heat of man’s life; and intelligence is called spiritual light, and likewise constitutes the light of man’s life. From this universal correspondence all other correspondences are derived; for all things both in general and in particular have relation to the good which is of love, and to the truth which is of intelligence.
