Hold the object that you wish to bless in your hands and envision energy flowing through your body and into the object.
Then, say this chant: “You may have once been but a simple (object that you are blessing: rock, candle book, etc). But now, with the witchy power bestowed in me, I grant you energy; so mote it be. And now take your place on the altar and forever blessed be.”
This spell can be used to purify any object, or just to give your altar a sense of spiritual cleanliness.
