From this also it is clear how holy and heavenly marriages are in
themselves, and how profane and diabolical adulteries are. And for this
reason adulterers make no account of Divine truths and thus of the Word,
and if they were to speak from the heart they would even blaspheme the
holy things that are in the Word. This they do when they have become
spirits after death, for every spirit is compelled to speak from the

As all the delights that man has in the natural world are turned into
correspondent delights in the spiritual world, so are the delights of
the love of marriage and the delights of the love of adultery. The love
of marriage is represented in the spiritual world as a virgin, whose
beauty is such as to inspire the beholder with the charms of life; while
the love of adultery is represented in the spiritual world by an old
woman, whose deformity is such as to inspire in the beholder a coldness
and death to every charm of life. Therefore in the heavens the angels
are beautiful according to the quality of marriage love in them, and in
the hells the spirits are deformed according to the quality of the love
of adultery in them. In a word, the angels of heaven have life in their
faces, in the movements of the body, and in their speech, in the measure
of their marriage love, while the spirits of hell have death in their
faces in the measure of their love of adultery.

In the spiritual world the delights of marriage love are represented to
the sense by odors from fruits and flowers of various kinds, while the
delights of the love of adultery are there represented to the sense by
the stenches from excrements and putridities of various kinds.
Moreover, the delights of the love of adultery are actually turned into
such things, since all things pertaining to adultery are spiritual
