624. Neither can their better spirits easily be together with the spirits of our earth, but must live separately. For they derive a different character from a different life, implanted by parents through the ages. As a result, they have an altogether different life, consequently a different nature that is closely associated with the heavenly ones, as observed before [564] when a rainbow was portrayed among the angels of their inward heaven.* And now, because their nature is closely joined to the heavenly ones, figuratively as the colors of the rainbow [are joined], and the natures of [their spirits and ours], being from a different root, are divergent, neither can the inward angels [of the two earths] be associated together. These are their angels who love golden sky blue. They do not want to allow the word Spiritual - as I now observe, because they are guiding my thoughts, thus my hand - for they say they do not want to know what is spiritual, but only what is heavenly. Many of them are guardian spirits, which is due to the fact that they speak little [cf. 598], but they do think, and their thoughts consequently derive from feelings. * See 262, footnote 3.
