Select a candle of an appropriate color. The candle should be new and never used for any other purpose.
Anoint the candle to impress your thoughts on it and to consecrate it to your purpose.
Before starting get clear on what you wish, then write your wish on new paper. Put this paper under the candle holder.
Lower or turn off other lights. Rub the anointing oil on your fingers and gently rub it onto the candle.
Light the candle and sit in quiet concentration upon your wish. Above all visualize the thing you want.
Use the burning candle as a focus of concentration.
When you feel that you have concentrated for long enough take the paper and burn it in the flame of the candle, with the thought that you are now projecting your wish into the beyond to find fulfillment.
Blow out the candle if its not consumed. Wrap it up in clean paper to use again on the same wish only!
