Use this spell to capture and deflect any baneful energies being sent your way. You'll need a small mirror and a black eyeliner pencil or marker. Use the eyeliner or marker to draw a large pentacle to cover the mirror. As you draw the symbol, say:

Earth is my power! Spirit, my shield! I am protected, as Nature doeth will!

Stand with the mirror in front of every window and entrance in your home, with the reflective side of the mirror facing out toward the outside world. Repeat the words above at each window or door as you make a circuit around your home. Then leave the mirror in a safe place where it's out in the open but unlikely to be touched. The top of a bookcase could make a good spot. Lay the mirror to rest flat upon the surface, placing it with its reflective face exposed to capture any lingering negative energies.
