13. With what eagerness they inquire into and imbibe the knowledges of things, such as appertain to the memory elevated above the sensual things of the body, was made manifest to me from this, that when they looked into those things which I knew respecting heavenly things, they passed hastily through them all, and continually saying that this and that were so and so. For when spirits come to man, they enter into all his memory, and excite thence whatever suits themselves: yea, what I have often observed, they read the things contained therein, as out of a book.# These spirits did this with greater dexterity and expedition, because they did not stop at such things as are heavy and sluggish, and which confine and consequently retard the internal sight, as all terrestrial and corporeal things do, when regarded as ends, that is, when alone loved: but they looked into things themselves; for such things, which are not clogged with things terrestrial, carry the mind upwards, thus into a broad field; whereas mere material things carry the mind downwards, and at the same time limit and shut it up. Their eagerness to acquire knowledges, and to enrich the memory, was manifest also from the following experience. Once while I was writing something concerning things to come, and they were at a distance, so that they could not look into those things from my memory, because I was not willing to read them in their presence, they were very indignant, and contrary to their usual behavior, they were desirous to inveigh against me, saying that I was one of the worst of men, and the like; and that they might give proof of their resentment, they caused a kind of contraction attended with pain on the right side of my head even to the ear. But these things did not hurt me. Nevertheless, in consequence of having done evil, they removed themselves to a yet greater distance, but presently they stood still again, desirous to know what I had written; such is their eager thirst after knowledges. # That the spirits who are with man, are in possession of all things appertaining to his memory (n.5853, 5857, 5859, 5860).
