1631. I was shown by actual experience how they operate, namely, not by gyres, like the heavenly [angels], but by meander-like, reciprocal motions, back and forth, portraying the combined workings of their mental imagery, which, to be genuine, must bend around so that by complete gyres, forms are exhibited. By an actual experience also, the quality of this operation was symbolized for me, specifically, by such ideas being slipped into the lips and so into the mouth and the inward parts of the head, symbolizing that they flow in by a way from without into their minds, but not by a way from within. Communication by means of the lips symbolizes ideas conceived by way of the senses, whereas it is genuine when they flow in from the Lord, thus by the inner way.
