1629. Later I was shown how those spirits operate who try to believe and to be angels on their own power, and how their belief and effort appears in a spiritual mental image. There was one choir which in its whirling movements simulated [angelic] gyres and with-in the gyres, the praising of the Lord as if they were angels. I did not understand them, but others did, who said that this was all simulated, and not angelic, because they did not have true belief. In my mental image it appeared to me as if composed of close threads, or a kind of net, whose webbing was so tight that nothing showed beyond the simple mental images of the words, in which there was no content. So the ideas did not go beyond the words, thus not beyond the praises depicted, which the words by themselves express. The words were thus closed to inward and more inward qualities because they were leading themselves, and were thus trying to praise the Lord from their own power. This net appeared white, because while these portrayals were certainly truths, they also symbolized self-righteousness.
