83. PART SECOND. DIVINE LOVE AND DIVINE WISDOM APPEAR IN THE SPIRITUAL WORLD AS A SUN. There are two worlds, the spiritual and the natural. The spiritual world does not draw anything from the natural, nor the natural world from the spiritual. The two are totally distinct, and communicate only by correspondences, the nature of which has been abundantly shown elsewhere. To illustrate this by an example: heat in the natural world corresponds to the good of charity in the spiritual world, and light in the natural world corresponds to the truth of faith in the spiritual world; and who does not see that heat and the good of charity, and that light and the truth of faith, are wholly distinct? At first sight they appear as distinct as two entirely different things. They so appear when one inquires what the good of charity has in common with heat, or the truth of faith with light; when in fact, spiritual heat is that good, and spiritual light is that truth. Although these things are in themselves so distinct, they make one by correspondence. They make one in this way: when man reads, in the Word, of heat and light, the spirits and angels who are with the man perceive charity instead of heat, and faith instead of light. This example is adduced, in order that it may be known that the two worlds, the spiritual and the natural, are so distinct as to have nothing in common with each other; yet are so created as to have communication, yea, conjunction by means of correspondences.
