95. That love begets heat, and wisdom light, is manifest from actual experience. When man loves he grows warm, and when he thinks from wisdom he sees things as it were in light. And from this it is evident that the first proceeding of love is heat, and that the first proceeding of wisdom is light. That they are also correspondences is obvious; for heat takes place [existit] not in love itself, but from love in the will, and thence in the body; and light takes place not in wisdom, but in the thought of the understanding, and thence in the speech. Consequently love and wisdom are the essence and life of heat and light. Heat and light are what proceed, and because they are what proceed, they are also correspondences.
96. That spiritual light is altogether distinct from natural light, any one may know if he observes the thoughts of his mind. For when the mind thinks, it sees its objects in light, and they who think spiritually see truths, and this at midnight just as well as in the daytime. For this reason light is predicated of the understanding, and the understanding is said to see; thus one sometimes declares of something which another says that he sees (that is, understands) that it is so. The understanding, because it is spiritual, cannot thus see by natural light, for natural light does not inhere in man, but withdraws with the sun. From this it is obvious that the understanding enjoys a light different from that of the eye, and that this light is from a different origin.
97. Let every one beware of thinking that the sun of the spiritual world is God Himself. God Himself is a Man. The first proceeding from His Love and Wisdom is that fiery spiritual [substance] which appears before the angels as a sun. When, therefore, the Lord manifests Himself to the angels in person, He manifests Himself as a Man; and this sometimes in the sun, sometimes outside of it.
98. It is from this correspondence that in the Lord the Lord is called not only a "sun" but also "fire" and "light." And by the "sun" is meant Himself as to Divine Love and Divine Wisdom together; by "fire" Himself in respect to Divine Love, and by "light" Himself in respect to Divine Wisdom.
99. SPIRITUAL HEAT AND LIGHT IN PROCEEDING FROM THE LORD AS A SUN, MAKE ONE, JUST AS HIS DIVINE LOVE AND DIVINE WISDOM MAKE ONE.
How Divine Love and Divine Wisdom in the Lord make one has been explained in Part I.; in like manner heat and light make one, because they proceed from these, and the things which proceed make one by virtue of their correspondence, heat, corresponding to love, and light to wisdom. From this it follows that as Divine Love is Divine Esse [Being] and Divine Wisdom is Divine Existere [Taking form] (as shown above, n. 14-16), so spiritual heat is thy Divine proceeding from Divine Esse, and spiritual light is the Divine proceeding from Divine Existere. And as by that union Divine Love is of Divine Wisdom, and Divine Wisdom is of Divine Love (as shown above, n. 35-39), so spiritual heat is of spiritual light, and spiritual light is of spiritual heat And because there is such a union it follows that heat and light, in proceeding from the Lord as a sun, are one. It will be seen, however, in what follows, that they are not received as one by angels and men.
100. The heat and light that proceed from the Lord as a sun are what in an eminent sense are called the spiritual, and they are called the spiritual in the singular number, because they are one; when, therefore, the spiritual is mentioned in the following pages, it is meant both these together. From that spiritual it is that the whole of that world is called spiritual. Through that spiritual, all things of that world derive their origin, and also their name. That heat and that light are called the spiritual, because God is called Spirit, and God as Spirit is the spiritual going forth. God, by virtue of His own very Essence, is called Jehovah; but by means of that going forth He Vivifies and enlightens angels of heaven and men of the church. Consequently, vivification and enlightenment are said to be effected by the Spirit of Jehovah.
101. That heat and light, that is, the spiritual going forth from the Lord as a Sun, make one, may be illustrated by the heat and light that go forth from the sun of the natural world. These two also make one in their going out from that sun. That they do not make one on earth is owing not to the sun, but to the earth. For the earth revolves daily round its axis, and has a yearly motion following the ecliptic, which gives the appearance that heat and light do not make one. For in the middle of summer there is more of heat than of light, and in the middle of winter more of light than of heat. In the spiritual world it is the same, except that there is in that world no daily or yearly motion of the earth; but the angels turn themselves, some more, some less, to the Lord; those who turn themselves more, receive more from heat and less from light, and those who turn themselves less to the Lord receive more from light and less from heat. From this it is that the heavens, which consist of angels, are divided into two kingdoms, one called celestial, the other spiritual. The celestial angels receive more from heat, and the spiritual angels more from light. Moreover, the lands they inhabit vary in appearance according to their reception of heat and light. If this change of state of the angels is substituted for the motion of the earth, the correspondence is complete.
102. In what follows it will be seen, also, that all spiritual things that originate through the heat and light of their sun, make one in like manner when regarded in themselves, but when regarded as proceeding from the affections of the angels do not make one. When heat and light make one in the heavens, it is with the angels as if it were spring; but when they do not make one, it is either like summer or like winter - not like the winter in the frigid zones, but like the winter in the warmer zone. Thus reception of love and wisdom in equal measure is the very angelic state, and therefore an angel is an angel of heaven according to the union in him of love and wisdom. It is the same with the man of the church, when love and wisdom, that is, charity and faith, make one in him.
