345. (5) This is effected by the lowest spiritual separated from what is above it. It was shown in Part Third that the spiritual flows down from its sun even to the outmosts of nature through three degrees, which are called the celestial, the spiritual, and the natural; that these three degrees are in man from creation, consequently from birth; that they are opened according to man's life; that if the celestial degree which is the highest and inmost is opened, man becomes celestial; if the spiritual degree which is the middle is opened, he becomes spiritual; but if only the natural degree which is the lowest and outermost is opened, he becomes natural; that if man becomes natural only, he loves only corporeal and worldly things; and that so far as he loves these, so far he does not love celestial and spiritual things, and does not look to God, and so far he becomes evil. From all this it is evident that the lowest spiritual, which is called the spiritual-natural, can be separated from its higher degrees, and is separated in such men as hell consists of. This lowest spiritual can separate itself from its higher parts, and look to hell, in men only; it cannot be so separated in beasts, or in soils. From which it follows that these evil uses mentioned above are effected on the earth by this lowest spiritual separated from what is above it, such as it is in those who are in hell. That the noxious things on the earth have their origin in man, thus from hell, may be shown by the state of the land of Canaan, as described in the Word; in that when the children of Israel lived according to the commandments, the earth yielded its increase, likewise the flocks and herds; but when they lived contrary to the commandments the ground was barren, and as it is said, accursed; instead of harvests it yielded thorns and briars, the flocks and herds miscarried, and wild beasts broke in. The same may be inferred from the locusts, frogs, and lice in Egypt.
