Circle

cir·cle/ˈsərkəl/

Noun:	A round plane figure whose boundary (the circumference) consists of points equidistant from a fixed center.

An ancient and universal symbol of unity, wholeness, infinity, the goddess, female power, and the sun. To earth-centered religions throughout history as well as to many contemporary pagans, it represents the feminine spirit or force, the cosmos or a spiritualized Mother Earth, and a sacred space.....

To me it means the sun, the moon, the stars.. the music of the spheres. Perfect cycles, eternity, without a beginning or an end...but a focal point.
