From the Vegetable Kingdom:--The tree, with its trunk and branches, leaves and fruits, stands upon its root, and from the soil where its root is draws and calls forth its sap, a coarser sap for the trunk and branches, a purer for the leaves, and a still purer and also nobler for the fruits and for the seeds in them; and this is done by means of heat from the sun. Here the branches, leaves, and fruit are distinct, and yet they extract together and instantly and from the same soil foods of such different purity and nobleness. From the Mineral Kingdom:--In the bosom of the earth in certain places there are minerals impregnated with gold, silver, copper, and iron. From vapors stored up in the earth the gold attracts its element, silver its element, copper and iron theirs, distinctly, together, and on the instant, and this by means of some power of unknown heat. As it is allowable to illustrate spiritual things by means of comparisons drawn from natural things, these will serve to illustrate how interior things, which are spiritual and celestial, and by which a man of the church has communication and conjunction with the heavens, can be drawn and called forth and extracted and eliminated from the Word in its outmosts, that is, the sense of the letter. Comparisons can be made with these, because all things in the three kingdoms of nature, animal, vegetable, and mineral, correspond to the spiritual things that are in the three heavens, as the food of the body with which a comparison has been made, corresponds to the food of the soul, which is knowledge, intelligence, and wisdom; a tree, with which also a comparison has been made, corresponds to man, the tree to man himself, the wood to his good, the leaves to his truths, and the fruits to his uses; so, too, gold, silver, copper, and iron, correspond to goods and truths, gold to celestial good, silver to spiritual truth, copper to natural good, and iron to natural truth. Moreover, these things have these significations in the Word. And what is wonderful, the purer are contained in the grosser and are drawn from them, as the animal spirit and the nerve fluid are contained in blood from which the original substances and nerve fibers draw and extract their distinct portions. So, again, fruits and leaves draw theirs from the gross fluid that is brought up from the soil by the wood and its bark, and so on. Thus comparatively, as has been said, the purer senses of the Word are drawn and called forth from the sense of the letter. (A.E., n. 1084.) VII. The Sense of the Letter
