5252. Moreover, a vast multitude was able to conceal themselves in one city, by reason of the fact that great part of them do not appear; for they who are of a different genius from others, or who turn themselves to different quarters there, thus to different falses and evils, or to different loves, immediately become invisible, and only those are visible who are in a similar faith and love with the others. Hence it is, that, sometimes, there appear to the inhabitants some that did not before do so, and that the inhabitants appear, to those who come thither, either few or many. The houses, also, disappear along with them, and reappear when they [i.e. the inhabitants] are again seen. Thus is it with things in the other life; which appears from the fact, that, as soon as a spirit disagrees in opinion with another, he vanishes. This is one way by which spirits render themselves invisible. Another is by phantasies.
