In occultism and magic the magic circle is a sacred and purified space where all rites, magical work, and ceremonials are conducted. It serves as a boundary for a reservoir of concentrated power and is the doorway from this world to the spirits and gods. The circle is symbolic of wholeness, perfection and unity; the creation of the cosmos; the womb of Mother Earth; and the cycle of the seasons and birth-death-regeneration. Within the circle it is believed possible to transcend the physical, to expose the mind to deeper and higher levels of consciousness.
The magician enters the circle expecting to unite the spirits or gods with the forces of nature in a harmonious relationship. Positive or desired deities are invoked, invited, and not commanded, evoked, to witness and participate in the rites. The circle also serves to protect those within it from negative spirits and energies. The circle is been thoroughly cleansed of all unfriendly spirits and negative energies, witches frequently symbolize this by sweeping the space with a boom.
Circles since ancient times have been reputed for magical properties. They were drawn around beds of the sick and mothers who recently bore children to protect them from demons. Their remnants which are seen in the stone circles of Britain give credence to the importance of the circle.
Circles were frequently cast for protection in order to ward off psychic attacks or physical intrusion of a home. They must be recast because their protective and magical powers are not permanent, but must be renewed with ceremonies.
The magic circle contains the four quarters, or cardinal points.
