The man who has lived quite selfishly and without care for the rights of others will suffer from strange visions in the after-death state. Those whom he has seriously wronged will appear before him repeatedly, reproaching him in some cases or denouncing him in others. This will continue until it becomes a kind of ghost-haunted torment, at first fatiguing him and later wearing him out to such an extent that he will fall into a sickly, wretched, fear-ridden state. At the lowest point of his misery, some other discarnate being will be sent to help him, to lead him to recognize his sinfulness and persuade him to repent. This entity may be a loving relative, an advanced mystic out of the body temporarily in sleep, or the man's own guardian angel. When this change of heart is effected, when the man confesses, repents, and resolves to mend his character, his persecution will stop.
