I've put together a webpage on the subject of Sacred Circles.
webpage provides links, bibliographic citations, resources, quotations,
notes, and comments on medicine wheels, henges, labyrinths, neopagan
sacred circles, holy circles, the symbolism and myths about circles and
spheres, sacred circle gardens, the four elements, and related topics.
This webpage includes information and photographs of our sacred circle garden at our home in Red Bluff, California.
Those folks who walk the circle in labyrinths, walking meditation or baguazhang might find some of the information in sacred circles to be of interest to them.
Here are a few pictures from our sacred circle garden. They were all taken a few years ago.
