Candles are one of my favorite things. Most of the candles in this mean something to me, or were given to me by someone important, or for something important. From personal decor to the purpose of scent to memory of those gone, this source of light produces warmth and comfort, not necessarily scent. The only scented piece represented is the oil, turning into smoke.
Light is most often portrayed as good, a path through darkness. Darkness surrounds, but does not consume. Ever think that this same light could bring a building to the ground? Light doesn’t have such a bright connotation anymore in that sense.
