"By its simple shape, circle includes everyone without distinction, welcomes and invites all to participate, and creates equality among those gathered. (...) The shape itself offers many benefits. Circle is the form of endlessness, continuation, calming down, pacifying. In a circle there's no beginning or end - once you're in the circle, you're there, participating in wholeness. Nobody is superior; no one is better than anyone else. We sit together in our differences in one nice, round shape. (...) It is the nature of circle to invite in, to provide both access and boundaries, to provide a participatory process, to set social expectations, and to absorb diverse, even opposing, views through the alchemy of a symbolic central 'fire'. (...) Circle provides a social container in which all voices may speak and be heard."
