Casting a circle is something that should be done prior to performing any kind of spell or ritual.  It creates a boundary between the energy within that circle and the energy outside of it.

When casting a circle, you should begin in the Eastern direction and go clockwise (known as “deosil” in witchy talk).  The following is one way in which to call the Guardians of each direction.  Each direction is associated with one of the four elements.  East is Air. South is Fire. West is Water.  North is Earth.

This particular casting of a circle calls upon the Guardians of the Watchtowers of the different directions.
