If you believe that a spell has been cast against you, place a large black candle in a cauldron (or a large black bowl). The candle must be tall enough to extend a few inches above the cauldron's rim. Affix the candle to the bottom of the cauldron with warmed beeswax or the drippings of another black candle so that it will not tip over.
Fill the cauldron to the rim with fresh water, without wetting the candle's wick. An inch or of the candle should remain above the water. Deep breathe, meditate, clear your mind, and light the candle. Visualize the suspected spells power as residing within the candle's flame. Sit in quite contemplation of the candle and visualize the power flowing and growing with the candles flame (yes, the power against). As the candle burns down, its flame will eventually sputter and go out as it contacts the water. As soon as the flame has been extinguished by the water, the spell will be dispersed!
