594.  How all things are so arranged in the heavens and in the hells that each and all of those who are there may be in their equilibrium, can in some measure be seen from what has been said and shown above respecting the heavens and the hells, namely, that all the societies of heaven are distinctly arranged in accordance with goods and their kinds and varieties, and all the societies of hell in accordance with evils, and their kinds and varieties; and that beneath each society of heaven there is a society of hell corresponding to it from opposition, and from this opposing correspondence equilibrium results; and in consequence of this the Lord unceasingly provides that no infernal society beneath a heavenly society shall gain any preponderance, and as soon as it begins to do so it is restrained by various means, and is reduced to an exact measure of equilibrium.  These means are many, only a few of which I will mention.  Some of these means have reference to the stronger presence of the Lord; some to the closer communication and conjunction of one or more societies with others; some to the casting out of superabundant infernal spirits into deserts; some to the transference of certain spirits from one hell to another; some to the reducing of those in the hells to order, and this also is effected in various ways; some to the screening of certain hells under denser and thicker coverings, also letting them down to greater depths; besides other means; and still others that are employed in the heavens above the hells.  All this has been said that it may in some measure be perceived that the Lord alone provides that there shall be an equilibrium everywhere between good and evil, thus between heaven and hell; for on such equilibrium the safety of all in the heavens and of all on the earth rests.

595.  It should be known that the hells are continually assaulting heaven and endeavoring to destroy it, and that the Lord continually protects the heavens by withholding those who are in it from the evils derived from their self, and by holding them in the good that is from Himself.  I have often been permitted to perceive the sphere that flows forth from the hells, which was wholly a sphere of effort to destroy the Divine of the Lord, and thus heaven.  The ebullitions of some hells have also at times been perceived, which were efforts to break forth and to destroy.  But on the other hand the heavens never assault the hells, for the Divine sphere that goes forth from the Lord is a perpetual effort to save all; and as those who are in the hells cannot be saved, (since all who are there are in evil and are antagonistic to the Divine of the Lord,) so as far as possible outrages in the hells are subdued and cruelties are restrained to prevent their breaking out beyond measure one against another.  This also is effected by innumerable ways in which the Divine power is exercised.
