From Divine Providence ~ Emanuel Swedenborg
No one who is in the pleasures of the lusts of evil can know anything about the pleasures of affections for good in which the angelic heaven is; for these two kinds of pleasure are directly opposite to each other in internals, and therefore interiorly are opposite in externals; although they differ little on the mere surface. For every love has its own pleasures, even the love of evil in those who are in lusts, such as the love of committing adultery, taking revenge, defrauding, stealing, doing cruel deeds, and in the most wicked even the love of blaspheming the holy things of the church, and of chattering venomously against God. The love of ruling from love of self is the fountain head of these pleasures. They are from the lusts that beset the interiors of the mind; and from the interiors they flow down into the body, and there excite the unclean things that titillate the fibers; and thus bodily pleasure springs from the mind's pleasure in accord with the lusts.What kinds of unclean things there are that titillate the bodily fibers of such persons it is granted to every one after death to know in the spiritual world. They are in general cadaverous, excrementitious, stercoraceous [consisting of or resembling dung or feces], reeking, and urinous things, for the hells of such abound in these unclean things. ... But after they have entered hell these filthy pleasures are turned into direful things. All this has been said that it may be understood what the happiness of heaven is, and the nature of it, .... For every thing is known from its opposite.
(Divine Providence 38)
