Mirrors?

I'm listening to an interesting audiobook - Angels, Guides & Ghosts by Sylvia Browne. In it, she talks about psychic attacks, being around people or things that are so negatively charged that they just drain you of your energy. She suggests starting the day by praying for God to surround you with mirrors, to reflect back what people give to you. If evil/negativity is directed toward you, the thinking goes, it will be reflected back and drive away whatever's causing it. If good is directed toward you, that will be reflected back and encourage the good to stay. You aren't asking for harm to come to anyone, just for whatever they give out to be reflected back to them. I thought it was an interesting concept, and I'm trying it. This place is bound to be just a whirlpool of negative energy.
