450. Among these twelve tribes, out of each of which twelve thousand are said to have been sealed, the tribe of Dan is not mentioned, but in its stead the tribe of Manasseh. 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)

209. There is no inflow from lower heavens into higher ones because this goes against the design. Rather, inflow is from the higher ones into the lower. The wisdom of angels of a higher heaven surpasses the wisdom of angels of a lower one by a ratio of thousands to one. This is also why angels of a lower heaven cannot talk with angels of a higher one. In fact, when they look in their direction they do not see them; their heaven looks like something cloudy overhead. However, angels of a higher heaven can see people who are in a lower heaven, though they are not allowed to carry on conversations with them, to prevent them from losing their wisdom, as already mentioned.
