8487. And the sun grew hot, and it melted. That this signifies that it vanishes away according to the degree of the increase of concupiscence, is evident from the signification of "the sun growing hot," as being increasing concupiscence (of which in what follows); and from the signification of "melting," as being to vanish away. That "the sun grew hot," denotes increasing concupiscence, is because "the sun" in a good sense signifies heavenly love, for the reason that the Lord is the Sun in the other life, and that the heat which is from it is the good of love, and the light is the truth of faith. (That the Lord is a sun, and that heavenly love is therefrom, see n. 1053, 1521, 1529-1531, 2120, 2441, 2495, 3636, 3643, 4060, 4321, 4696, 5084, 5097, 5377, 7078, 7083, 7171, 7173, 7270.) Consequently in the opposite sense "the sun" denotes the love of self and of the world, and "the heat" or "growing hot of the sun" denotes in this sense concupiscence.
 How the case herein is, that the good of truth, which is signified by "the manna," vanished according to the degree of increasing concupiscence, which is signified by its "melting when the sun grew hot," shall be briefly told. The good of truth, or spiritual good, is indeed given to the man of the spiritual church when he is being regenerated; but as all the delight of the love of self and of the world, which had previously constituted his life extinguishes this good (because they are opposites), therefore the pure good of truth cannot long abide with that man, but it is tempered by the Lord by means of the delights of the loves which had belonged to his previous life; for unless this good were so tempered, it would become undelightful to him, and thus would be loathed. Such is heavenly good at first with those who are being regenerated. Insofar therefore as the delights of the loves of self and of the world rise up, so far the good of heavenly love vanishes away, for as before said they are opposites; and it is the same the other way about.
 Hence it is that in heaven there are alternations of states, to which correspond the alternations of times in the world (n. 8426), and that thus by means of alternations they are remitted into the delights of natural pleasures; for without a change of the states the good of heavenly love would become as it were dry, and of slight estimation; but it is otherwise when it is tempered by means of natural delights at the same time, or successively. From this it is that at first when the manna was given to the sons of Israel every morning, the quail was also given in the evening; for by "the quail" is signified natural delight, and also the delight of concupiscence (n. 8452).
 But be it known that the concupiscences into which they who are in heaven are remitted when it is evening with them, are not concupiscences that are opposite to heavenly good, but those which in some measure agree with this good; for they are the delights of conferring benefits in a large way, and consequently something of glory, in which nevertheless there is benevolence and a study to be of service; they are also the delights of magnificence in the embellishments of home and the ornaments of dress, and many other similar delights. Such are the delights which do not destroy the good of heavenly love (but still they hide it), and at last, according to the degree of the man's regeneration, they become the ultimate planes of heavenly good, and then they are no longer called "concupiscences," but "delights." That without a tempering by means of such things the good of heavenly love becomes as it were dry, and afterward is loathed as a thing of no value, is signified by the sons of Israel calling the manna dry food, and vile food, as we read when the quail was no longer given them, in Moses:
The rabble that was in the midst lusted a lust, whence the sons of Israel also wept again, and said, Who shall feed us with flesh? now our soul is dry, our eyes have not anything [to look at] except the manna (Num. 11:4, 6).
The people spake against God, and against Moses: Wherefore have ye made us come up out of Egypt to die in the wilderness? there is no bread, nor water; now doth our soul loathe this most vile bread (Num. 21:5).
Jehovah afflicted thee, and made thee hunger, and fed thee with manna, which thou knewest not, neither did thy fathers know; that He might teach thee that man doth not live by bread alone, but by every utterance of the mouth of Jehovah doth man live (Deut. 8:3).
 In like manner as by "the manna," so also by "the unleavened bread," there is signified good pure from falsities (n. 8058), which bread is for a similar reason called "the bread of misery" (Deut. 16:3). From all this it can now be seen what is meant by the good of truth vanishing away according to the degree of the increasing concupiscence, which is signified by "the manna melting when the sun grew hot."
