We find calm or vigor from aromatic essences released by the heat of the flame in scented candles. One might find oneself mesmerized by the intoxicating glow of the flame of a candle. A fascinating thing is a flame, dancing on the end of the wick of a candle, beckoning us to wonder and marvel at its existence. Fire is a strange thing. It may be difficult to understand, but what we perceive as the flame of a candle is not truly fire at all, rather it is an effect of fire.
Actual fire is virtually invisible to the naked eye.
It is intense heat created by a chemical reaction. The light we see, as what we call a flame, is the luminescence of substances which are super heated but not burned. Like a when a blacksmith works a horseshoe made of iron he has removed from hot coals, the iron glows bright orange but is not on fire. Elements passing through the flame of a candle glow brightly in the heat of an invisible fire. You may have heard of limelight in reference to the 19th century stage or theater.
