If you think you like candles, you haven't met my mom. She lights five candles in the kitchen at the same time, to the point where you can't distinguish one smell from another. Growing up with that, I've developed a fondness for candles. But, unlike my mom, I only light one at a time so that I can really bask in the scent that I've chosen. Sometimes, though, I don't choose by scent, but by color.
One of my favorite metaphysical books is How to Heal With Color by Ted Andrews. In it, he explains how to use candles as a method of healing. The color of the candle, he purports, is released into the air as the wick burns. Before using the candle, he suggests "dressing" by rubbing olive oil on it in one direction, but if you don't want to do that, you can merely send a wave of positive energy in the direction of the candle, affirming that you will be using it for a healing purpose.
Here's a brief list from his book of ailments and which colors you should use to relieve them. If you aren't a fan of candles, you can also practice directing colorful energy through your hands onto the problem area:
Abdominal cramps: Yellow
Aches (ear): Turquoise
Aches (head): Blue / Green
Aches (muscle): Light Orange
Arthritis: Violet or Blue Violet
Blisters: Ice Blue
Nausea: Ice Blue
Rash: Yellow and Turquoise
Swelling: Ice Blue
I wish I had remembered this list two weeks ago, when I was suffering from a case of Shingles! I love color healing, but I have to confess that I do often forget to practice it. I'll start trying to do it more regularly and let you know if I have any results.
For now, though, since I don't have any candles that aren't brown or black, I'll just be satisfied with my Maple Pancakes-scented candle.
