evated and can perceive such
things as are of heat out of heaven, provided it loves its consort in that
degree.

(15) Otherwise love or the will draws down wisdom or the understanding
from its elevation, that it may act as one with itself.

(16) Love or the will is purified by wisdom in the understanding, if they
are elevated together.

(17) Love or the will is defiled in the understanding and by it, if they
are not elevated together.

(18) Love, when purified by wisdom in the understanding, becomes spiritual
and celestial.

(19) Love, when defiled in the understanding and by it, becomes natural
and sensual.

(20) The capacity to understand called rationality, and the capacity to
act called freedom, still remain.

(21) Spiritual and celestial love is love towards the neighbor and love
to the Lord; and natural and sensual love is love of the world and love
of self.

(22) It is the same with charity and faith and their conjunction as with
the will and understanding and their conjunction.

399. (1) Love or the will is man's very life. This follows from the
correspondence of the heart with the will (considered above, n. 378-381).
For as the heart acts in the body, so does the will act in the mind; and
as all things of the body depend for existence and motion upon the heart,
so do all things of the mind depend for existence and life upon the will.
It is said, upon the will, but this means upon the love, because the will
is the receptacle of love, and love is life itself (see above, n. 1-3),
and love, which is life itself, is from the Lord alone. By the heart and
its extension into the body through the arteries and veins it can be seen
that love or the will is the life of man, for the reason that things that
correspond to each other act in a like manner, except that one is natural
and the other spiritual. How the heart acts in the body is evident from
anatomy, which shows that wherever the heart acts by means of the vessels
put forth from it, everything is alive or subservient to life; but where
the heart by means of its vessels does not act, everything is lifeless.
Moreover, the heart is the first and last thing to act in the body. That
it is the first is evident from the fetus, and that it is the last is
evident from the dying, and that it may act without the cooperation of
the lungs is evident from cases of suffocation and swooning; from which
it can be seen that the life of the mind depends solely upon the will
