5464. (1) They place themselves at the back, below and above, and there they thrust in their thoughts; they turn the thoughts of another spirit, and thus of a man, to himself, to his own power, to his own praise, in a word, to the proprium. Almost all infernals know how to do this. (2) Others gaze upon various parts of the body and upon the head and, where they see anything black, they know the proprium still rules there - for the proprium is black, because it is of the love of self - and, then, they seek to learn what of self is there, and, when they find out, they infuse their own thoughts there, and lead [their victim] whithersoever they will. (3) Some look into the forehead; and, if it appears black, they then lead him; likewise, if it is grayish-white like a plastered wall, inasmuch as this indicates simulated external sincerity; but from him in whom they see human flesh they withdraw, and him they do not lead. (4) Some cast a black veil over his face and also over his breast, and thus they magically take away his thoughts of the neighbor, and oblige and compel him to think of himself; and so they lead him, but not like they do others who are black of themselves: the former return immediately. (5) Some enshroud another in darkness and convey [him] into the dark, and so compel him to think of self. (6) From the color around a spirit or man - black, white, flesh-color, or yellow - they conclude something about the man's state as to his proprium, or self-love. Where it is black, there is self-love: such a one is led; and it is according to the intensity of the black. (7) Some only perceive by means of the thoughts of another - for there is a general law of thoughts - and these insinuate themselves into them and turn them to [the victim's] proprium and love of self, in all ways - by phantasies, by magic; and by the aid of many of the hells; and, so, they drive him to thinking about himself; and, when it comes to that, he is in their power. (8) Sirens know how to insinuate themselves into the various affections which are the ruling love of a man; and so they take him with them. Also, they know how to reduce the thoughts of another, magically, even to the sensual, which is the extreme external; and, when he is reduced to that, they induce various phantasies and lead him whithersoever they wish. It is the sensual of man where his self-love, or proprium, resides: so far as he can be drawn up, or elevated, out of that, as to the thoughts, towards interiors, so far he can be led away from his proprium. Man's sensual, at this day, is, with most people, wholly corporeal, and has not anything spiritual. (9) It was granted me to perceive when I was in the proprium, and when not in the proprium. When in the proprium, I was fit for nothing; wherefore, I was led out of it by the Lord, as far as that could be done. Hence is manifest what the love of self, and the love of the world for the sake of self, is. When [any] are led in the proprium and borne away, they appear to be led down through the surrounding places; which is according to the changes of the state of the thoughts. There were some such of the Swedish nation, whose desire it had been thus to reduce the thoughts of other spirits to subjection, and so to lead them whithersoever they would; but they did not know how, save one or two of them. They were in the western quarter.
