rt; also the terms concord, discord, folly [vecordia], and
other similar terms expressive of love and its affections. There are like
expressions in the Word, because the Word was written by correspondences.
Whether you say love or will it is the same, because the will is the
receptacle of love, as was explained above.

379. It is known that there is vital heat in man and in every living
creature; but its origin is not known. Every one speaks of it from
conjecture, consequently such as have known nothing of the correspondence
of natural things with spiritual have ascribed its origin, some to the
sun's heat, some to the activity of the parts, some to life itself; but
as they have not known what life is, they have been content with the mere
phrase. But any one who knows that there is a correspondence of love and
its affections with the heart and its derivations may know that the
origin of vital heat is love. For love goes forth as heat from the
spiritual sun where the Lord is, and moreover is felt as heat by the
angels. This spiritual heat which in its essence is love, is what inflows
by correspondence into the heart and its blood, and imparts heat to it,
and at the same time vivifies it. That a man grows hot, and, as it were,

and cold according to its decrease, is known, for it is felt and seen;
it is felt by the heat throughout the body, and seen by the flushing of
the face; and on the other hand, extinction of love is felt by coldness
in the body, and is seen by paleness in the face. Because love is the
life of man, the heart is the first and the last of his life; and because
love is the life of man, and the soul maintains its life in the body by
means of the blood, in the Word blood is called the soul (Gen. 9:4;
Levit. 17:14). The various meanings of soul will be explained in what
follows.

380. The redness, also, of the blood is from the correspondence of the
heart and the blood with love and its affection; for in the spiritual
world there are all kinds of colors, of which red and white are the
fundamental, the rest deriving their varieties from these and from their
opposites, which are a dusky fire color and black. Red there corresponds
to love, and white to wisdom. Red corresponds to love because it
originates in the fire of the spiritual sun, and white corresponds to
wisdom because it originates in the light of that sun. And because there
is a
