I attended a Fire Ceremony yesterday, as it was the new moon.
The New Moon is a good time to have ceremony and set new goals.
The Full Moon is good for releasing old beliefs and patterns or habits.
At fire, we blow our goals / issues into a stick and throw it into the fire, giving our problems to spirit to handle for us. It brings such a feeling of release and a lightness after throwing your sticks in the fire.
You can do ceremony in a 3 day window around the full and new moons, so the day before, day of the full / new moon, or the day after, to experience the highest energy.
… this does not mean you cannot have fire anytime…. you can never have too many fire ceremonies!
