I didn't go into detail on this. I wonder if it's more related to religion here. Maybe it's keeping the evil eye from the couple. She's working on her degree at UCLA and is studying zeffa and also danced in Egypt. When I do candle, I try to think of all the ritual uses and meanings of fire and incense.
Fire can be the raging forest fire or the gentle, welcome light of a candle in a window.

Just remember that the candles are extensions of your arms and try to keep your body energy flowing out to where the flames flicker. I start my students with their unlit candles.
