Take this last shooting, in Florida, the shooter said he was hearing voices, and the voices were demons. How many crimes are committed by those who hear voices? "The Devil made me do it?

If you are hearing voices, what can you do to protect yourself?
Covert and overt actions are meant to take away our freedom. If you stand on seven principles of Universal Law, you are unbeatable.

When people see only the Power level and the Project level, they can justify playing power games, including going on the astral plane to goad people into acts of violence in an attempt to defend themselves. There is always a backlash to the games that are played.
In other words, those who use the astral plane as a weapon against others end up shooting themselves in the proverbial foot.
