A certain spirit who wanted to take credit for the deeds he had done and the doctrines he had taught while living in the world went off toward the right and came upon some people who were not like him. In order to attach himself to them, he said that he was a nobody and would like to serve them, but they had been sensing what he was like from the moment he approached them, while he was still far away. Their immediate answer was that he was not the kind of person he said; he wanted to be important and consequently would not be able to get along with them, since they were not. Embarrassed by this, he left, amazed that they could tell from such a distance.
Since their sensitivities are so acute, evil spirits cannot go near any environment or community inhabited by good spirits, who love each other. Let the good spirits just approach and the evil ones begin to suffer, complaining and crying.
A certain evil spirit was brash and bold enough to force his way into a community that lay at the very threshold of heaven. The instant he arrived, he found he could hardly breathe and sensed that he stank like a corpse, so he slipped back down.
