Answer: There are no witches, ghouls, devils, demons, or other evil spirits.
These are all qualities of a person. In Kabbalah, there are many names of both pure (altruistic) and impure (egoistic) forces. However, they are all inside a person. It does not mean that we need to cast out demons. We must correct our egoistic qualities.
Do not imagine them in the form of an image. Do you want to change something? Then, just change yourself, your egoism. Let’s say that yesterday your egoism was -20 and today it is –10. This means that you have cast some “demon” out of yourself.
