The link I have above is to a website that has done a fair amount of homework on this subject. They do a pretty good job of representing the 'standard' understanding of color associations for candle magic. I'm not going to write down the spell I used here because I have yet to write it into my Book of Shadows. Furthermore, it is more effective to make your own spell then to use one from someone else.
All of that said, I have a blue candle burning on my altar right now. It is infused with the oils of rose and chamomile. While the packaging for this candle says it is for positive energy, I'm not using it for that. The nice thing about candles in magic is that the people who sell them can suggest what you use them for but you ultimately decide how you use them. I could discuss that and ramble along on that topic for a while but that's not the objective with my post here.
I wanted to talk about healing magic and candle magic. Candle magic is something that works fairly quickly, in my opinion. If I wanted to do magic that manifest within a week or a few days, I get a candle that burns quickly and use it for this purpose. Candles that take longer to burn can equate to a longer time period until manifestation. That is, however, if you are keying your spell to the consumption of the candle. It is possible to focus the spell's manifestation on different elements of the use of the candle.
I have a big fat pillar candle on my altar. It is one that I burn when ever I am praying or meditating. It serves as a visual focus for me and as a representation of my offering to the Gods. Other candles have different purposes and my use of them reflects it. They all have the same basic function, which is to be a physical tie to what I am working to accomplish and a psychological key to help me enter the correct mindset to engage in the task I have. I like candle magic because even the act of lighting the candle helps to settle and focus me. It is a ritual all by itself.
Healing magic... Oh how much of a mixed blessing that is. On one hand, we like to think that healing magic makes us feel wonderful and somehow removes all ailments. It doesn't do that, however. Properly constructed healing magic works to help the subject reach the state that will be maximum health for them at that time. It doesn't specify that they are what is commonly understood as healthy. I've done healing magic that brought that result. I've also done healing magic that brought death. It was not my intent to bring death, but death was the healthiest state for the person to be in, for it released them from the great suffering that they were in.
Healing magic, like love magic, is a double edged sword. My blue candle is focused upon my psychological healing. Since I have put it on my altar and started burning it, it hasn't alleviated my flashbacks, night terrors, or the trembling fear that stalks my heart often these days. Instead, it has been forcing me to confront them by placing situations and events into play that serve either as a mirror or draws these buried things up into the light of my conscious mind. It is not comfortable, gentle, or anything even remotely resembling pleasant.
It is as difficult to heal as it is to be wounded. In many ways, I believe it is harder. I think this healing magic that I am working on is like calling in another pair of hands to assist me in forcing the infection out of a wound that had scabbed over. That other pair of hands won't shrink from something because it causes me discomfort. It is very, very hard to accept that magic works like this but when you do accept it, you become far more successful.
Right now, however, I look forward to when the pain eases back to more tolerable levels. I don't believe I'm going to cast anything to make this healing progress faster because these kinds of things, if they go quickly, seem to turn very, very ugly in the midst of moving rapidly before hitting that desired result.
