292. Everything that a man thinks and wills, and consequently speaks and does, flows in from one sole Fountain of life, and yet that one Fountain of life, which is the Lord, is not the cause of a man's thinking what is evil and false. This can be illustrated by the following circumstances in the natural world. From the sun of this world proceed heat and light; and these two flow into all subjects and objects that appear before the eyes, not only into subjects that are good and objects that are beautiful, but also into subjects that are evil and objects that are ugly, producing in them various effects. For they flow not only into trees that bear good fruit but also into trees that bear bad fruit, and even into the fruits themselves, imparting to them quickening power. They likewise flow into good seed and also into tares; also into shrubs that have a good use or are wholesome, and also into shrubs that have an evil use or are poisonous. Yet it is the same heat and the same light, and in these there is no cause of evil; but the cause is in the recipient subjects and objects. [2] The heat which hatches eggs in which lie the bird of night, the screech-owl and the viper acts in the same way as when it hatches eggs in which lie the dove, the bird of paradise and the swan. Set eggs of both kinds under a hen and they will be hatched by her heat, which in itself is free from harm. What then has the heat in common with those evil and noxious things? The heat that flows into the marsh and the dung-hill, and into dead and putrefying matter acts in the same way as when it flows into the vine sapling and the fragrant herb, and into luxuriant vegetation and bodies pulsing with life. Who does not see that the cause is not in the heat but in the recipient subject? On the other hand, the same light brings out in one object colours that are pleasing, and in another colours that are net pleasing; it even brightens itself up and sends out brilliant rays in white objects, but in objects that verge towards black it dims and darkens itself. [3] It is the same in the spiritual world; for there also are heat and light from its Sun, which is the Lord, and these flow from that Sun into their subjects and objects. The subjects and objects there are angels and spirits, in particular, what pertains to their will and understanding, the heat there being the Divine Love going forth, and the light there the Divine Wisdom going forth. These are not the cause of their being received differently by one and by another; for the Lord says, He maketh His sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust. Matt. v. 45. By the Sun in the highest spiritual sense is meant the Divine Love, and by the rain the Divine Wisdom.
