3340. To this light there is an opposite darkness, and to this heat there is an opposite cold; in these live the infernals. Their darkness is from the falsities in which they are, and their cold is from the evils; and the more remote they are from truths, the greater is their darkness; and the more remote they are from good, the greater is their cold. When it is permitted to look into the hells where such infernals are, there appears a dark cloud in which they have their abode; and when any exhalation flows out thence, there are perceived insanities that exhale from falsities, and hatreds that exhale from evils. A light is indeed sometimes granted them, but it is a deceptive one; and this is extinguished with them, and becomes darkness, the moment they look at the light of truth. Heat also is sometimes granted them, but it is like that of an unclean bath; and this is changed into cold with them as soon as they observe anything of good. A certain person was let into that dark cloud where the infernals are, in order that he might know how the case is with those who are there; he being protected by the Lord by means of angels. Speaking from thence with me he said that there was there so great a rage of insanity against good and truth, and especially against the Lord, that he was amazed that it could possibly be resisted; for the infernals breathed nothing but hatred, revenge, and slaughter, with such violence that they desired to destroy all in the universe; so that unless this rage was continually repelled by the Lord, the whole human race would perish.
