of separation._ XVI. _The first of them is a vitiated state of mind._
XVII. _The second is a vitiated state of body._ XVIII. _The third is
impotence before marriage._ XIX. _Adultery is the cause of divorce._ XX.
_There are also several accidental causes of cold; the first of which
is, that enjoyment is common (or cheap), because continually allowed._
XXI. _The second is that living with a married partner, from a covenant
and compact, seems to be forced and not free._ XXII. _The third is,
affirmation on the part of the wife, and her talking incessantly about
love._ XXIII. _The fourth is, the man's continually thinking that his
wife is willing; and on the other hand, the wife's thinking that the man
is not willing._ XXIV. _As cold is in the mind it is also in the body;
and according to the increase of that cold, the externals also of the
body are closed._ We proceed to an explanation of each article.

in that world a sun proceeding from the Lord, who is in the midst of it;

what is the source of spiritual heat, and that spiritual heat is love.
But we will also briefly explain the source of spiritual cold. It is
from the sun of the natural world, and its heat and light. The sun of
the natural world was created that its heat and light might receive in
