Needed:
Bread
Salt
Incense: frankincense, cinnamon, or pepper
Procedure:
Bread is offered to the household guardians as a libation, and the salt is kept in the heart of the home to ground any evil that might enter. After you do this, burn a purifying or protecting incense such as frankincense, cinnamon, or pepper moving it from room to room while you visualize any negativity fleeing from your home. As you go, chant over and over your words of power:
Smoke of air and fire and earth
Cleanse and bless this home and hearth
Drive away all harm and fear
Only good may dwell in here.
