that the understanding
can be elevated and can receive and perceive things that are of the light
of heaven; for the correspondence is plenary. To see from correspondence
is to see the lungs from the understanding, and the understanding from
the lungs, and thus from both together to perceive proof.

414. (14) Love or the will can in like manner be elevated and can receive
such things as are of heat out of heaven provided it loves wisdom, its
consort, in that degree. That the understanding can be elevated into the
light of heaven, and from that light draw forth wisdom, has been shown in
the preceding chapter and in many places above; also that love or the will
can be elevated as well, provided it loves those things that are of the
light of heaven or that are of wisdom, has also been shown in many places.
Yet love or the will cannot be thus elevated through anything of honor,
glory, or gain as an end, but only through a love of use, thus not for
the sake of self, but for the sake of the neighbor; and because this love
is given only by the Lord out of heaven, and is given by the Lord when
man flees from evils as sins, therefore it is that love or the will can
be elevated by these means, and cannot without these means. But love or
the will is elevated into heaven's heat, while the understanding is
elevated into its light. When both are elevated, a marriage of the two
takes place there, which is called celestial marriage, because it is a
marriage of celestial love and wisdom; consequently it is said that love
also is elevated if it loves wisdom, its consort, in that degree. The
love of wisdom, that is, the genuine love of the human understanding is
love towards the neighbor from the Lord. It is the same with light and
heat in the world. Light exists without heat and with heat; light is
without heat in winter time, and with heat in summer time; and when heat
is with light all things flourish. The light with man that corresponds
to the light of winter is wisdom without its love; and the light with man
that corresponds to the light of summer is wisdom with its love.

415. This conjunction and disjunction of wisdom and love can be seen
effigied, as it were, in the conjunction of the lungs with the heart.
For the heart can be conjoined to the clustering vesicles of the bronchia
by blood sent out from itself, and also by blood sent out not from itself
but from the vena cava and the aorta. Thereby the respiration of the body
can be
