133. Now something will be said about the heat of heaven. That heat in its essence is love. It goes forth from the Lord as the Sun which, as has been shown in the previous section, is Divine Love in the Lord and from the Lord. It is clear, then, that the heat of heaven is spiritual just like the light of heaven because from the same source.# There are two things that go forth from the Lord as a Sun, Divine Truth and Divine Good. Divine Truth is manifested in the heavens as light, and Divine Good as heat. Yet, Divine Truth and Divine Good are so united that they are not two but one. Nevertheless, with the angels they are separated, for there are angels who receive Divine Good more than Divine Truth, and there are those who receive Divine Truth more than Divine Good. Those who receive more Divine Good are in the Lord's celestial kingdom, and those who receive more Divine Truth are in the Lord's spiritual kingdom. The most perfect angels are those who receive both in the same degree. # There are two origins of heat, and also two origins of light, namely, the sun of the world and the Sun of heaven (n. 3338, 5215, 7324). The heat which goes forth from the Lord as the Sun is the affection which is of love (n. 3636, 3643); and hence spiritual heat is, in its essence, love (n. 2146, 3338, 3339, 6314).
