Many rituals within Wicca are used when celebrating the Sabbats, worshipping the deities, and working magic. Often these take place on a full moon, or in some cases a new moon, which is known as an Esbat. In typical rites, the coven or solitary assembles inside a ritually cast and purified magic circle. Casting the circle may involve the invocation of the "Guardians" of the cardinal points, alongside their respective classical elements; air, fire, water, and earth. Once the circle is cast, a seasonal ritual may be performed, prayers to the God and Goddess are said, and spells are sometimes worked; these may include various forms of 'raising energy', including raising a cone of power to send healing or other magic to persons outside of the sacred space.
