A locket bears a minature grid of the Yantra and may be worn around the neck. You may use any suitable chain or thread. This should not be placed in a wallet or handbag. Given the rigors of everyday life, it possible for the power of a locket Yantra to decrease slightly, over the years. If this were to happen, simply repeating Locket Talismans Instructions will restore the talisman's power. In comparison, a fixed Yantra is to be placed in your home or workplace and it's power will usually increase, as it is worshipped over a period of time.
