596. There are two kingdoms into which the heavens are divided, the celestial kingdom and the spiritual kingdom (of which see above, n. 20-28). In like manner the hells are divided into two kingdoms, one of which is opposite to the celestial kingdom and the other opposite to the spiritual kingdom. That which is opposite to the celestial kingdom is in the western quarter, and those who are in it are called genii; and that which is opposite to the spiritual kingdom is in the northern and southern quarters, and those which are in it are called spirits. All who are in the celestial kingdom are in love to the Lord, and all who are in the hells opposite to that kingdom are in the love of self; while all who are in the spiritual kingdom are in love towards the neighbor, and all who are in the hells opposite to that kingdom are in love of the world. Evidently, then, love to the Lord and the love of self are opposites; and in like manner love towards the neighbor and love of the world are opposites. The Lord continually provides that there shall be no outflowing from the hells that are opposite the Lord's celestial kingdom towards those who are in the spiritual kingdom; for if this were done the spiritual kingdom would perish (for the reason given above, n. 678, 579). These are the two general equilibriums that are unceasingly maintained by the Lord.
