181. Since there are degrees of love and wisdom, there are also degrees of heat and light. By heat and light we mean spiritual heat and light, the kind of heat and light angels have in the heavens, and the kind people possess inwardly in the interior regions of their minds. For people possess the same warmth of love and the same light of wisdom as angels. In the heavens the case is as follows. The nature and measure of the love angels possess determines the nature and measure of the warmth they experience. Their light is likewise determined by their wisdom. The reason is that love exists in them in a state of warmth, and wisdom in a state of light, as we have shown before. It is the same on earth with people, but with the difference that angels feel that warmth and see that light, whereas people do not. The reason is that people are living in a world of natural warmth and light, and as long as they are they do not feel spiritual warmth except as the result of some delighting of their love, and do not see spiritual light except as the result of a perception of truth. Now because as long as a person is living in a world of natural warmth and light he is not at all aware of the spiritual warmth and light in him, and nothing of these can be known except through experience gained from the spiritual world, therefore we must say something here in particular about the warmth and light possessed by angels and their heavens. From there and nowhere else is enlightenment on this subject possible.
