Carry a special coin or metal in your pocket blessed for the purpose of strengthening your resolve not to engage in vicious gossip. When you are with people who are maligning someone, reach in your pocket and grasp the coin firmly with the intention that your clenched fist is akin to your clenched tongue. Say to yourself that for as long as you hold the coin in your hand, you will also hold your tongue.
