d reason, is, because it is at the same time a fear for
the loss of eternal happiness, not only of its own but also of its
married partner's, and because also it is a defence against adultery. In
respect to the first consideration,--that it is a just fear for the loss
of its own eternal happiness and of that of its married partner, it
follows from every thing which has been heretofore adduced concerning
love truly conjugial; and also from this consideration, that married
partners derive from that love the blessedness of their souls, the
satisfaction of their minds, the delight of their bosoms, and the
pleasure of their bodies; and since these remain with them to eternity,
each party has a fear for eternal happiness. That the above zeal is a
just defence against adulteries, is evident: hence it is like a fire
raging against violation, and defending itself against it. From these
considerations it is evident, that whoever loves a married partner
tenderly, is also jealous, but is just and discreet according to the
man's wisdom.

372. It was said, that in conjugial love there is implanted a fear lest
it should be divided, and a grief lest it should perish, and that its
zeal is like a fire raging against violation. Some time ago, when
meditating on this subject, I asked the zealous angels concerning the
seat of jealousy? They said, that it is in the understanding of the man
who receives the love of a married partner and returns it; and that its
quality there is according to his wisdom: they said further, that
jealousy has in it somewhat in common with honor, which also resides in
conjugial love; for he that loves his wife, also honors her. In regard
to zeal's residing with a man in his understanding, they assigned this
reason; because conjugial love defends itself by the understanding, as
good does by truth; so the wife defends those things which are common
with the man, by her husband; and that on this account zeal is implanted
in the men, and by them, and for their sake, in the women. To the
question as to the region of the mind in which jealousy resides with the
men, they replied, in their souls, because it is also a defence against
adulteries; and because adulteries principally destroy conjugial love,
that when there is danger of the violation of that love, the man's
understanding grows hard, and becomes like a horn, with which he strikes
the adulterer.
