Naturally candles have polarities. Everything in our program has positive and negative polarities, as it is an electro magnetically based program.
Dressing a candle is no more than putting your vibration, thoughts and outcome you want into the candles vibration force. [This works the same way with crystals and stones]. Dress the candle with oil. Use whatever oil you prefer or what a specific spell asks you to use. Rub oil on the candle in a downward motion from the top to the middle and then from the bottom to the middle.
To send something away, stroke the candle 7 times from the middle of the candle out to the ends. Always stroke the candle in one direction.
Dab the remaining oil from your fingers onto your third eye and on your breast bone [heart chakra]. Then state your intent or the purpose of the candle.
Now light the candle and let it burn down.
