One of them also showed me how they speak to each other by changes of facial expression, that is, by tiny little movements of their muscles - especially those around the lips. This is why there are in that region so many interwoven muscular chains. But it is around the eyes, I presume, that their feelings are displayed, that is, their more inward feelings, for the face is a reflection of the inward person, as was explained [528] in regard to the spirits who display faces, with their changing shapes and varying features. But what they showed me by changes in the tissues around the lips, I could not understand - I could only feel the changes - because my face was not, from early childhood, trained in them and accustomed to them. The fact that they cannot put on pretenses, but follow the true order of their life, is likewise the reason why they are unable to conceal anything whatsoever from their companions, without their knowing it at once, and knowing what they are like, and what they are dreaming up, and what they have done. So life with them is spiritual, and such persons can at once be singled out, and then taught, and be reformed.
