And he made him a tunic* of various colors. That this signifies the appearances of truth thence, whereby the spiritual of the natural is known and distinguished, is evident from the signification of a “tunic,” as being the truth of the natural, of which hereafter; and from the signification of “various colors,” as being the appearance of truth by which the spiritual of the natural is known and distinguished. That these are signified by “various colors” cannot be known by anyone unless he knows that colors appear in the other life equally as in the world-colors which in beauty and variety far surpass those in this world-and unless he knows what is the source of these colors. The colors seen in the other life are from the variation of the light there, and are so to speak modifications of intelligence and wisdom; for the light which appears there is from the Divine truth that is from the Lord, or is the Divine spiritual from Him, or what is the same, is Divine intelligence and wisdom, which appears as light before the eyes of angels and spirits. Hence it is evident what is signified by the colors from that light, namely, qualities of truth, thus its appearances, and that they appear from the affections of good and truth.

As everyone receives the heaven that is outside of him in accordance with the quality of the heaven that is within him, so in like manner does everyone receive the Lord, since it is the Divine of the Lord that makes heaven. And for this reason when the Lord becomes manifestly present in any society His appearance there is in accord with the quality of the good in which the society is, thus not the same in one society as in another. This diversity is not in the Lord; it is in the angels who behold Him from their own good, and thus in accordance with their good. And they are affected by His appearance in accordance with the quality of their love, those who love Him inmostly being inmostly affected, and those who love Him less being less affected; while the evil who are outside of heaven are tortured by His presence. When the Lord is seen in any society He is seen as an angel, but is distinguished from others by the Divine that shines through.

Every unity has its existence from diversity, for a unity that is not the result of diversity is not anything; it has no form and therefore no quality. When, on the other hand, a unity comes into existence from various parts, and these various parts are in a perfect form in which each attaches itself in series, like a congenial friend to another, then the quality is perfect. So heaven is a unity resulting from the arrangements of various parts in the most perfect form, for the heavenly form is the most perfect of all forms.
