7870. 'On that night' means their state - a state of evil. This is clear from the meaning of 'night' as a state when there is nothing but evil and falsity. For night describes the opposite of day and thick darkness the opposite of [clear] light, and 'day' and '[clear] light' mean a state in which truth and good reign. This being so, 'night' also means the last phase of the Church, for at that time falsities and evils reign because there is no faith or charity, see 2353, 6000. In addition 'night' means when vastation is completed, 7776, and also damnation, 7851. From all this it is evident that the state of those who are in hell is called 'night'. Not that the thick darkness of night envelops them, for they can see one another. But since the state of truth and good which exists in heaven is called 'day', the state of falsity and evil is called 'night'. Also thick darkness exists in hell when any light at all from heaven flows into it; for then the inferior light which they see by is reduced to nothing and becomes thick darkness.

[2] The source of the inferior light they see by is, it is true, light from the Lord coming through heaven; for in the next life no light comes from anywhere else. But among those in hell that light from Him enters by way of the ability to understand what is true. The ability enabling them to understand remains with them, as it does with every human being, however much they may be steeped in evil or falsity. But when that heavenly light passes on into their will - that is to say, into unwillingness to understand - and consequently passes into the evil and falsity that reside with them, the heavenly light is turned for them into inferior light resembling that emitted from a coal fire. And, as has been stated, that inferior light is converted into utterly thick darkness by the light of heaven when this flows into it. Regarding the inferior light in hell, its being like that emitted from a coal fire, see 1528, 3340, 4418, 4571; and regarding its conversion into thick darkness at the presence of the light of heaven, 1783, 3412, 4533, 5057, 5058, 6000. From all this it may be recognized that in the next life the kind of light each one has depends on whether his ability to understand is furnished with truths springing from good or with falsities arising from evil.

5057. I once saw a mortar, standing by which there was a man who had an instrument made of iron. In his delusion the man thought he was pounding human beings in the mortar, tormenting them dreadfully. He took great delight in what he was doing, and that delight was communicated to me to enable me to know the nature of it and how strong it was in people of his kind. It was a hellish delight, and angels told me that it was the kind that reigned among the descendants of Jacob. These never felt more delighted than when they could treat gentile nations in a cruel fashion, exposing those they had slain to be devoured by wild animals and by birds, cutting up with saws and axes those who were still alive, and making them pass through the brickkiln, 2 Samuel 12:31, also striking little children and hurling them to the ground. No one has ever been commanded to behave in these ways, nor has anyone ever been permitted to do so other than the kind of people in whom the nerve in the thigh has been put out of joint, 5051. Such spirits live beneath the right heel, where the adulterers who are also cruel dwell.

[2] In view of this it is astonishing that anyone should ever believe that that nation was chosen or elected in preference to any other one. Believing that they were so elected many people go on to convince themselves of the idea that one's life is of no consequence at all but that election and consequent acceptance into heaven is attributable to mercy alone, irrespective of the life one has led. Yet anyone of sound reason can see that to think in that way is to think contrary to the Divine. The Divine is mercy itself, and therefore if the attainment of heaven were attributable to mercy alone irrespective of the life one leads, all would be accepted, no matter how many these might be. To thrust anyone down into hell to suffer torment there, when it was possible for him to be received into heaven, would not be mercy but the opposite of mercy, and to elect one in preference to another would not be righteousness but the opposite of righteousness.

[3] Consequently those who have believed and convinced themselves of the idea that some have been elected and the rest have not been elected, also of the idea that admittance into heaven is attributable solely to mercy regardless of the life they have led, have been for the most part the kind of people who have led evil lives. These are told, as I have also heard and seen on several occasions, that the Lord never refuses anyone entrance into heaven, and that if they like they can find this out from experience. They are therefore raised up into some community of heaven whose inhabitants have led their lives under the influence of an affection for good, that is, they have led charitable lives. But when those raised up arrive there they begin, being evil, to suffer pain and inner torment because their life is contrary to that of heaven. And when heavenly light shines on them they look in that light like devils that are almost wholly devoid of human appearance. Some have sunken faces; some are all teeth, looking like crates; and some, who are different again, look like monsters. Thus they are horrified at themselves and hurl themselves headfirst into hell; and the deeper they can go, the better it is for them.
