Take a photo of the person you wish to bind.  If you don’t have a photo, you can use a small piece of paper and write the name on it..   If you do not know the name of the person, write “My workmates” or something similar.  Fold this paper up and place it inside a glass jar. Half fill the bottle with water, and place it in the freezer, saying:
 

 “I place your in the freezer.
 I bring a halt to slander, gossip and lies.
 For the good of all concerned, and harming none,
So Mote it be!”

Or
 

“I place you in the freezer,
To halt to those actions which bring harm to others
For the good of all concerned, and harming none,
So Mote it be!”

Leave the bottle in the freezer for as long as you think you need to.  Each day open the freezer door and chant over and over again:
 

          “Freezer freezes, ____(Harm/Gossip/lies)____ stops”

While chanting, visualise the person stopping whatever it is they have been doing.  When they have stopped doing the harm, take the jar out of the freezer, saying:
 

“I remove you from the freezer,
As you have ceased your harmful actions
But should you start them again,
I will return you”

Keep the jar in a safe place, ready to put it back in the freezer if they start up again, repeat the spell.
