3086. To have any idea at all, even a very general one, of the things contained here in the internal sense, it should be recognized that the whole of this chapter is dealing with Divine truth that was to be joined to Divine Good. That is to say, Divine Good flowed into the natural man, that is, into the facts, cognitions, and matters of doctrine there, for these belong to the natural man insofar as they are in his memory. And by means of that influx, Divine Good brought light and life, and ordered all that was there; for all light, life, and order in the natural man result from influx from the Divine, as anyone may know if he pays the matter any attention. By means of that influx affection comes into being, first of all a general affection for truth, the affection dealt with in these two verses - its origin, in 3077, 3078; its nature, in 3079-3081; and the initial stage of its introduction, in 3082-3084. But the verses that follow directly after them, in the internal sense describe that process further, that is to say, investigation of that truth, and also the separation of the elements received from the mother which had been allied to it first of all, and so on. But I realize that these arcana are too deep to be understood easily, the reason being, as has been stated, that they are not known. Nevertheless since the internal sense describes them, and does so in great detail, what else is to be done but explain them, no matter how much they appear to be beyond human apprehension? At least one may see from this how deep the arcana are within the internal sense of the Word, and also that those arcana are such as to be hardly visible at all in the light of the world which man has during his lifetime, but that they are always seen more clearly and plainly to the extent that he passes from the light of the world into the light of heaven, the light into which he passes after death, and so sees in the light in which blessed and happy souls, that is, angels, dwell.

3219. When angels are engaged in discussion about thoughts and ideas, and about influx, birds are seen at the same time in the world of spirits - the forms which the birds take being determined by the subject under discussion. This explains why birds in the Word mean rational concepts or things comprising thought, 40, 745, 776, 991. On one occasion birds came into view, and I saw that one was dark and ugly, two fine and beautiful. When I saw them, behold! certain spirits were there who then descended on me so violently as to send a tremor into my sinews and bones. I supposed that then, as had happened several times before, evil spirits were assailing me in an attempt to destroy me; but that was not so. When the tremor ceased and the spirits who had descended on me stopped moving, I spoke to them asking what it was all about. They said that they had fallen from a certain angelic community in which discussion was taking place about thoughts and influx, and that they had been of the opinion that the things which comprise thought flow in from without, that is to say, by way of the external senses, as is the appearance. But the angelic community in which they were present were of the opinion that it flowed from within. And because they themselves had been governed by falsity they had fallen from there. No one had cast them down, for angels do not cast anyone down from among themselves. It was owing to the falsity reigning in them that they had fallen from there. This had been the reason why it had happened. From this I was given to know that discussion in heaven about thoughts and influx is represented by birds - the discussion of those in whom falsity reigns by dark and ugly birds, but that of those who are governed by truth by fine and beautiful birds. I was at the same time told that all the ideas comprising thought enter into it from within, not from without, even though those ideas seem to do so. I was also told that it is contrary to order for what is posterior to flow into what is prior, or what is grosser into what is purer, and so for body to flow into soul.
