All cultures hold the circle as an esteemed shape. A circle indicates connection; every part of the circle is needed to make it complete. Circles and sacredness go together; the sun, seen by us as a circle, is essential for life. We are each a part of some circle; perhaps a circle of friends, a family circle, a sewing circle. The circle is a vital part of Unity symbol. We are connected, one with God, and the circle reminds us of this sacred connection.
