" The most common form of sacred space to the witch is the magick circle. The circle is a symbol of the infinite and finite. It is everything and nothing. It is the Ouroboros, the serpent eating its own tail, symbolic of the never-ending cycle of creation and destruction, birth and death, and a symbol of the cosmos without beginning or end. "
