Here's something for ya Ann. I use a combination of what Tropicality's suggestion consists of mixed with Peter Harwoods suggestion. Yes, protective energy projection (aura whatever she called it.. I don't know what I call it, I just do it) and calling upon the assistance of Christ.
Powerful stuff right there. It can knock it out in a matter of minutes. Personally, I have received the ability to fight against black magic and dark entities through Christ therefore I couldn't vouch as to whether or not anything would work without his assistance. Anything I have been given that deals with the psychic, paranormal, ect., realm, came from Christ and is enhanced by him and him only.
My 2 cents of course. Take it as you will. Good luck to you dear.
