38. No one who is in the pleasures of the lusts of evil can know anything of the joys of the affections of good in which the angelic heaven is. These pleasures and joys are opposites in internals and hence inwardly in externals, though superficially they may differ little. Every love has its enjoyments; the love of evil with those in lusts also has, such as the love of committing adultery, of taking revenge, of defrauding, of stealing, of acting cruelly, indeed, in the worst men, of blaspheming the holy things of the church and of inveighing against God. The fountainhead of those enjoyments is the love of ruling from self-love. They come of lusts which obsess the interiors of the mind, from these flow into the body, and excite uncleannesses there which titillate the fibers. The physical pleasure springs from the pleasure which the mind takes in lusts. [2] After death everyone comes to know in the spiritual world what the uncleannesses are which titillate the body's fibers in such persons and comes to know the nature of them. In general they are things cadaverous, excrementitious, filthy, malodorous, and urinous; for their hells teem with such uncleannesses. These are correspondences, as may be seen in the treatise _Divine Love and Wisdom_ (nn. 422-424). After one has entered hell, however, these filthy delights are turned into wretchedness. This has been told in order that it may be understood what heaven's felicity is and its nature, of which we are now to speak; for a thing is known from its opposite. 39. It is impossible to describe in words the blessedness, satisfaction, joy and pleasure, in short, the felicity of heaven, so sensibly perceived there. What is perceived solely by feeling, cannot be described, for it does not fall into ideas of thought nor, therefore, into words. For the understanding sees only and sees what is of wisdom or truth, but not what is of love or good. Those felicities are therefore inexpressible, but still they ascend in like degree with wisdom. They are infinitely various, and each is ineffable. I have heard this, also perceived it. [2] These felicities enter when a man, of himself and yet from the Lord, casts out the lusts of the love of evil and falsity. For these felicities are the happinesses of the affections of good and truth, the opposites of the lusts of the love of evil and falsity. Those happinesses begin from the Lord, thus from the inmost, diffuse themselves thence into things lower even to lowermost things, and thus fill the angel, making him a body of delight. Such happinesses are to be found in infinite variety in every affection of good and truth, and eminently in the affection of wisdom.
