Candle magic is one of the easiest magics out there, ergo a good place to start. Candle magic sounds fancy, but it's simple magic. Anyone with a candle can do it. A good example of this is when you blow out the candles on a birthday cake and wish. Think about it. This is a type of magic. You are deciding a goal, focusing on that goal, and visualizing the result. This time, however, you will state your intent instead of wishing it.
What candle should I use?
Well, any, but the smaller, the better, especially for spells that require that you wait until the candle burns out on its own. I own three small candles made specifically for candle magic that I use, but, as I said before, you can use whatever you want. However, try not to use a candle over. If you do, it may yield unwanted outcomes.
The colors on a candle have meanings, as you may know.
Red ~ courage, health, and love.
Pink ~ friendship or sweet love.
Orange ~ attraction. It also stands for encouragement.
Gold ~ financial gain, solar endeavors, and success at business.
Yellow ~ persuasion and protection.
Green ~ financial gain, abundance and fertility.
Light blue ~ health, understanding, and patience.
Dark blue ~ vulnerability and depression.
Purple ~ power, it's also the color of ambition.
Brown ~ related to the Earth and animals.
Silver ~ reflection, intuition, and lunar connections.
Black ~ negativity and banishment.
White ~ purity and truth, but in most Pagan traditions, it can be used in place of any color.
After you have selected the candle, oil or dress it. This will help you and the candle establish a psychic link between one another. You will need natural oils for this. Begin at the top and rub the oil down to the middle, then start at the base and rub it up towards the middle where you left off.
The most basic candle magic uses colored paper to match your candle and intent. Write your intent on it, fold it while concentrating on your intent. You can say a small incantation while doing this. It doesn't have to be fancy. Then you burn the paper and hold on as long as possible. When you can't anymore, you drop it into a cauldron or firesafe container. Allow the candle to burn out completely, then dispose of the candle in any manner you see fit.
