Candles are a miniaturized version of the behemoth element from which they come: Fire - The Sun. As we are talking about Christmas symbolism, and honoring the return of the light (in terms of the Christ Light, or the Sun's rays lingering longer upon the body of Earth), it makes sense to use candles as a way to galvanize the passion touching our hearts this time of year. Candles are light bringers, and so they are vessels for pure positive energy in the form of spiritual illumination. Remember my earlier question about Angels? There's no evidence to refute Angels living within every flame we ignite - so honor the light beings with every candle you light this season. Candles can speak to our souls because fire is a foundational element of our spiritual combustion. Consider this, and imagine the warmth of your spiritual presence spreading out to all of humankind - light a candle in the name of your brother, in honor of your sister, for the human family - this kind of soul-warming is present within you as the heat is inherent to the candle flame.
