To protect your home, collect four large, pleasing stones while out walking. On each one, paint a large cross in red or white, visualizing it locking out any dangers that may threaten you. Place a stone as close as you can to each of the corners of your property, working in a clockwise direction. If you live in a flat or apartment, you may need to place the stones under the building or inside it. After a few months, return the stones to the land, and renew the spell with some fresh ones.
