and according to the increase of that cold, the externals also of the body are closed._ We proceed to an explanation of each article. 235. I. THERE ARE SPIRITUAL HEAT AND SPIRITUAL COLD; AND SPIRITUAL HEAT IS LOVE, AND SPIRITUAL COLD IS THE PRIVATION THEREOF. Spiritual heat is from no other source than the sun of the spiritual world; for there is in that world a sun proceeding from the Lord, who is in the midst of it; and as it is from the Lord, it is in its essence pure love. This sun appears fiery before the angels, just as the sun of our world appears before men. The reason of its appearing fiery is, because love is spiritual fire. From that sun proceed both heat and light; but as that sun is pure love, the heat thence derived in its essence is love, and the light thence derived in its essence is wisdom; hence it is manifest what is the source of spiritual heat, and that spiritual heat is love. But we will also briefly explain the source of spiritual cold. It is from the sun of the natural world, and its heat and light. The sun of the natural world was created that its heat and light might receive in them spiritual heat and light, and by means of the atmospheres might convey spiritual heat and light even to ultimates in the earth, in order to produce effects of ends, which are of the Lord in his sun, and also to clothe spiritual principles with suitable garments, that is, with materials, to operate ultimate ends in nature. These effects are produced when spiritual heat is joined to natural heat; but the contrary comes to pass when natural heat is separated from spiritual heat, as is the case with those who love natural things, and reject spiritual: with such, spiritual heat becomes cold. The reason why these two loves, which from creation are in agreement, become thus opposite, is, because in such case the dominant heat becomes the servant, and _vice versa_; and to prevent this effect, spiritual heat, which from its lineage is lord, then recedes; and in those subjects, spiritual heat grows cold, because it becomes opposite. From these considerations it is manifest that spiritual cold is the privation of spiritual heat. In what is here said, by heat is meant love; because that heat living in subjects is felt as love. I have heard in the spiritual world, that spirits merely natural grow intensely cold while they apply themselves to the side of some angel who is in a state of love; and that the case is similar in regard to the infernal spirits, while heat flows into them out of heaven; and that nevertheless among themselves, when the heat of heaven is removed from them, they are inflamed with great heat.
