Each animal species (insects, wild animals, mammals, reptiles, birds) has a specific diet. You can try your own experiment: leave a few crumbs of food in a room – right away certain bugs will appear.

If it is honey you will have wasps, if it is cheese you will have mice.

How did they sense from afar that there was something for them to nibble on? But as soon as you clean up, they disappear.
This phenomenon explains how when people entertain certain thoughts, desires or feelings that are neither luminous nor pure, entities that like these impurities immediately arrive and settle in to feed off of them.

But if people purify themselves, if they become reasonable, these entities leave them to make way for luminous spirits. Very few people know how to read from the book of living nature that is right there in front of them.

You will say that these are only small details; yes, but they have boundless applications in the psychic life.
