Hematite

Although long associated with psychic awareness, astral travel, scrying and healing, among other things, it has always been a favorite of mine when it comes to protection. Specifically, when I’m using protection magic on my home. It can be used as you would a mirror at the all the entrances of your home. Placing a hematite stone at all entrances reflect any negative energy that comes your way back out and away from you. As you place the hematite you can say the following or something like it.

Shield me now, like a mirror
Negativity come no nearer
In this hour and on this day
As I will, so mote it be.

The stones can be taken up and cleansed once a month on the Full Moon by allowing them to lay in the light of the moon for a few hours. You can also lay the stones out on the ground so that any negative energy can move out of the stone and into the earth to be transformed and neutralized.
