About fields, I believe I have spoken earlier [167, 210, 973, 1839], but this concerned their extension and active energy. Regarding their nature and how they work, very much remains to be told. At this point, only this will be said, that they work in an amazing way, and can be compared to other fields which either agree or disagree, or either coalesce, so to speak, or collide with one another. Those with clashing fields are able to sense in an instant whatever is opposed to them and, as if by their own field, turn it into what is agreeable to them-even very minute elements in another's field. Such fields also appear in people on earth, having a somewhat denser quality. The fields of wicked spirits so unnoticeably distort good thoughts into evil ones, using all the surrounding material that is in the person's thought, that the person or spirit cannot at all tell that this is going on. And if I had not been enabled to reflect on the matter, and in fact, view it quite clearly, and know who he was and where he was, I would never have been able to learn that things like these were happening. If the person just knows what is true and good, and what is opposite to these, they turn it all around to suit their character, so that whatever is in the person's memory they bend in this manner. 1748, 29 April.
