This unique practice gave me a Wiccan practitioner who I know. Here it is.
You take a jar and you put iniside any sharp object. (Knives, blades, scissors...) will you piss inside and sigillerete the jar with the stopper and the black wax. You will bury the jar under the land.
Who will does harm or hurt you, they will do the same for seven more times with the objects that you had put in a jar, every time will take them in his hands.
