Candles can often be crucial background to a ritual, setting the scene, creating a mood for a ceremony involving other aspects or tools, but with Candle Magic the candle takes center stage. Red candles, green candles; fat or thin; hand-dipped, solid-color and perfumed with essential oils or plain, shop-bought wax tubes, the candle is a focus for meditation, contemplation or the gathering and directing of energy. As with all rituals, this focusing of energy must be treated with respect - more so than usual when dealing with the most powerful and dangerous of all elements - Fire!

Magic, ceremony, ritual and worship itself is, and should be, a work of art created by each person, suiting their requirements and their personality.
