Unity Candle Ceremony is a form of ritual where a bride and groom together light a central candle from their own individual candles. The couple’s two individual candle, represent their own individual life from birth till the day of their marriage. Once the couple light the middle candle, they blow out their individual candles. The middle lit candle represents them as one and no longer two.
I have performed Sand Ceremony for many couples including the famous wedding at Costco for Eli & Sue.
