The tribe of Dan is not mentioned because that tribe represented and signified such as are treated of in what now follows in this chapter, whom John thus describes, "After these things I saw, and behold a great multitude which no one could number, out of every nation and all tribes and peoples and tongues, standing before the throne and before the Lamb, clothed in white robes, and palms in their hands" (verse 9). For these are such as were not in the very truths of heaven and the church, but in the good of life according to the doctrinals of their religion, and these were for the most part not genuine truths but falsities, and yet these falsities were accepted by the Lord as truths, because such were in the good of life, and on account of this the falsities of their religion were not tainted with evil, but inclined to good. The others were taken in place of the tribe of Dan because the tribe of Dan was the last of the tribes, and therefore signified, in the Lord's kingdom, the ultimates in which those are who are in the good of life and of faith according to their religion in which there are no genuine truths. (Respecting the tribe of Dan see Arcana Coelestia 1710, 3920, 3923, 6396, 10335)

From all this it can be seen what the form of heaven is, namely, that it is the most perfect of all in the inmost heaven; in the middle heaven it is also perfect, but in a lower degree, and in the outmost heaven in a degree still lower; also that the form of one heaven has its permanent existence from another by means of influx from the Lord. But what communication by influx is cannot be understood unless it is known what degrees of height are, and how they differ from degrees of length and breadth. What these different degrees are may be seen above (38).
