Arcana Coelestia # 165
165. The nakedness of which they were not ashamed means innocence. This is quite clear from what follows. When integrity and innocence left them they were then ashamed of their nakedness, and it seemed disgraceful to them, and so they hid themselves. It is additionally clear from the things represented in the world of spirits that the nakedness of which they were not ashamed means innocence. Indeed when spirits wish to exonerate themselves and prove that they are blameless they present themselves naked to witness their innocence. This is particularly clear with the innocent in heaven, who look like young children, naked, and wearing garlands round them that accord with their particular variety of innocence. But those who do not possess so much innocence appear clothed in splendid and shining clothes - you might call them brightest silk - like angels when seen from time to time by the prophets.

5059. When those who have lived in ways that are the opposite of conjugial love - that is, in adulterous ways - have drawn near me, they have introduced pain into my loins, the severity of which has depended on the nature of the adulterous life led by them. That influx also demonstrated that the loins corresponded to conjugial love. Furthermore their hell is situated beneath the area behind the loins, under the buttocks, where they live in filth and excrement. These are also the things that give them delight, for such filth and excrement correspond to the pleasure they gain in the spiritual world from such things. But in the Lord's Divine mercy more will be said about these spirits when the hells are described as a whole and individually.
