Find a large mirror, one you can position so that you are able to sit before it. Burn a white and a black candle in front of the mirror and meditate there for awhile, focusing on purifying your energy. Repeat this each night, three nights in a row. Also try burning some cinnamon, frankincense, gardenia, or sandalwood incense. Once you are done each night, don't blow the candles out, snuff them out instead.
After the third and final night, bury the wax remaining from the candles.
