This simple spell can be used to protect your home from unwanted energy. It can also be carried on you.
Step 1 - Get a mirror. Any mirror. Size doesn't really matter. For your house, you want it to fit on your door. If you want to carry it on you, something smaller of course.
Step 2 - Cleanse the mirror with water containing salt and hyssop.
Step 3 - Charge/consecrate your mirror using the smoke from Frankincense, Myrrh and/or Patchouli. While doing this focus your intent on the mirror reflecting any negative energies or influence back to their source.
Step 4 - Attach the mirror (reflective side to the outside) on the back of your door. So it looks like you have a mirror on the inside of your door facing backwards. If you choose to keep a small protection mirror on you. SImply put it in your pocket, purse, or wallet.
