39. The blessings, the happiness, the delights and pleasures, in a word, the joys of heaven, cannot be described in words; but in heaven they are perceptible to the feelings; for what is perceptible to feeling alone cannot be described because it does not fall into ideas of thought, and thus not into words. For it is the understanding alone that sees; and it sees the things that pertain to wisdom or truth, but not the things that pertain to love or good. For this reason these joys are inexpressible, yet they ascend in like degree with wisdom: their varieties are infinite, and each is ineffable. I have heard this, and I have also perceived it.
 These joys, however, enter as man, as if from himself but still from the Lord, puts away the lusts of the love of evil and falsity; for these joys are those of the affections of good and truth, and are the opposites of the lusts of the love of evil and falsity. The joys of the affections of the love of good and truth begin from the Lord, thus from the inmost; and thence they pour themselves forth into lower things, even to the lowest, and thus fill the angel, making him become as it were wholly a delight. Such joys, with their infinite varieties, are in every affection of good and truth, especially in the affection of wisdom.
