Light a white candle and your favorite incense.  Meditate a short while on the problem.  Invoke the Spirits of Protection for you and yours.  Then take a piece of brown paper, like from a grocery bag, on it use a lead pencil to print and write  the name of the offending person or people.  If unknown people are involved, also print and write, “and all persons unknown that are causing harm to me!”
 
Cross off each line forcefully and say,  forcefully, 
   " I freezename(s) to be bound by this spell, unable to cause any more harm to  (name(s)!   As I will, so mote it be! " 

    Then put a spoonful of used coffee grounds on the brown paper, fold it small, and place it in the freezer.  Leave it until the problem is completely resolved.   I  wrap a rubber band, string, twist tie, or what have you, to keep the coffee grounds from falling out of the paper.  You can also use a zip loc bag.   Be sure and burn the candle completely up.  Don't use that candle for a different purpose.
