[2] There are two kinds of temptation, the first involving things of the understanding, the second those of the will. When a person's temptation involves those of the understanding, evil spirits activate only the evil deeds he has carried out, which are meant here by 'unclean beasts'. And with these they accuse and condemn. They even activate his good deeds as well, which are also meant here by the 'clean beasts'; but these they corrupt in a thousand ways. At the same time they also activate his thoughts, which are also meant here by 'bird', and in addition they activate the things meant here by 'things creeping over the ground'. This kind of temptation however is mild and is perceived only through the recollection of such experiences, and a kind of mental anguish resulting from this.

[3] When however someone's temptation involves things of the will, it is not so much his deeds and thoughts that are activated. Instead there are evil genii, as evil spirits of this type may be called, who inflame him with the evil desires and the foul loves in which he is steeped, and in this way direct their attack through the person's very desires. They do this so wickedly and secretly that one cannot possibly believe it is they who are doing it. In fact they worm their way in no time at all into the life of his desires, and almost instantaneously twist and convert the affection for good and truth into the affection for evil and falsity. They act in such a way that the individual inevitably thinks that these things come from himself and flow forth of his own free will. This kind of temptation is very severe, and is felt as inward pain and burning torment. This subject is dealt with later on. I have been allowed from much experience to know and realize that this is true, and to know also when evil spirits or genii were flowing in and overwhelming, and from where, who they were and how they did it. In the Lord's Divine mercy these experiences will be described in detail later on.
