269. And there was a rainbow round about the throne in aspect like unto an emerald. That this signifies the appearance of Divine truth in the heavens surrounding the Lord is evident from the signification of a rainbow in aspect like unto an emerald, as denoting the appearance of Divine truth in its circumference; for a rainbow round about the throne signifies Divine truth around it, and in aspect signifies appearance. The reason why the appearance of the rainbow was like that of an emerald, is that it indicated the Last Judgment, for the colour of this stone is green, and green signifies truth obscured. Divine truth in its splendour appears either of a sky-colour, or of various colours disposed in beautiful order, as those of the rainbow; but when it is obscured it appears of the colour of an emerald. The heaven which is called the former heaven was that on which judgment was to be executed, and which was about to perish (see Apoc. 21:1) which caused the obscurity. This is why mention is made of a rainbow, and its aspect like that of an emerald. The reason why the rainbow signifies Divine truth in the heavens in its order, and thence in its beauty, is that there are infinite varieties of truth from good in the heavens; and when they are represented by colours, they present the appearance of a beautiful rainbow. This is why the rainbow was made a sign of the covenant after the flood (Genesis 9:12-17). (That there are infinite varieties in the heavens may be seen in the work, Heaven and Hell 56, 405, 418, 486, and in the small work, The Last Judgment 13; and in Arcana Coelestia 684, 690, 3744, 5598, 7236, 7833, 7836, 9002. That colours in heaven appear from the light there, and that they are its modifications and variegations, n. 1042, 1043, 1053, 1624, 3993, 4530, 4742, 4922; and that the colours appear various according to the varieties of the states of truth from good, and thence of intelligence and wisdom, n. 4530, 4677, 4922, 9466. That rainbows appear in heaven, and whence and what they are, n. 1042, 1043, 1623, 1624, 1625.)

684. THE COMMUNITIES THAT CONSTITUTE HEAVEN

There are three heavens, the first where good spirits are, the second where angelic spirits are, and the third where angels are. One heaven is interior to and purer than the next, which means that they are entirely distinct and separate from one another. The first heaven divides into countless communities, as do the second and the third, and each community consists of many individuals who, because of the harmony and unanimity that exist among them, in effect constitute one person. At the same time, all the communities in effect constitute one human being. Communities differ in nature from one another according to the way their mutual love and faith in the Lord varies. These differences are so countless that it is not possible to count up even the most general kinds of them. Even the smallest of differences fits into the perfectly ordered arrangement of the whole, and so contributes in perfect unanimity to a general unity, as does the general unity to the unanimity among individuals. Each individual therefore contributes to the happiness of all, and all to that of each individual. Consequently every angel and every community is an image of the whole of heaven and is so to speak heaven in miniature.
