510. Everyone goes to his own society in which his spirit had been in the world; for every man, as regards his spirit, is conjoined to some society, either infernal or heavenly, the evil man to an infernal society and the good man to a heavenly society, and to that society he is brought after death (see n. 438). The spirit is led to his society gradually, and at length enters it. When an evil spirit is in the state of his interiors he is turned by degrees toward his own society, and at length, before that state is ended, directly to it; and when that state is ended he himself casts himself into the hell where those are who are like himself. This act of casting down appears to the sight like one falling headlong with the head downwards and the feet upwards. The cause of this appearance is that the spirit himself is in an inverted order, having loved infernal things and rejected heavenly things. In this second state some evil spirits enter the hells and come out again by turns; but these do not appear to fall headlong as those do that are fully vastated. Moreover, the society itself in which they had been as regards their spirit while in the world is shown to them when they are in the state of their exteriors, that they may thus learn that even while in the life of the body they were in hell, although not in the same state as those that are in hell itself, but in the same state as those who are in the world of spirits. Of this state, as compared with those that are in hell, more will be said hereafter. 511. In this second state the separation of evil spirits from good spirits takes place. For in the first state they are together, since while a spirit is in his exteriors he is as he was in the world, thus the evil with the good and the good with the evil; but it is otherwise when he has been brought into his interiors and left to his own nature or will. The separation of evil spirits from good spirits is effected by various means; in general by their being taken about to those societies with which in their first state they had communication by means of their good thoughts and affections, thus to those societies that they had induced to believe by outward appearances that they were not evil. Usually they are led about through a wide circle, and everywhere what they really are is made manifest to good spirits. At the sight of them the good spirits turn away; and at the same time the evil spirits who are being led about turn their faces away from the good towards that quarter where their infernal society is, into which they are about to come. Other methods of separation, which are many, will not now be mentioned. 512. LIII. THIRD STATE OF MAN AFTER DEATH, WHICH IS A STATE OF INSTRUCTION FOR THOSE WHO ENTER HEAVEN.
