Guardian Angels: Protective, Familiar and Sympathetic Spirits
511. With the exception of protective spirits, are there wicked spirits who attach themselves to individuals to tempt them and cause them to struggle between good and bad?
“‘Attached’ is not accurate. It is very true that bad spirits try to draw you from the path of righteousness when they find an opportunity to do so. However, when one of them attaches to an individual it does so simply because it hopes the person is going to listen to them. In such a case, there is a struggle between a good and a bad spirit, and whoever successfully influences that individual prevails.”
