The Medicine Wheel, or Circle of Life, is found in many tribes and in many parts of the world. The compass points North, South, East and West in four directions. Mother Earth is below and Father Sky is above.
The circle shape represents life. We change like the seasons as we pass through life, traveling through the part of the circle. The center of the circle is the Spirit, from which everything extends and everything returns.
One 2D Medicine Wheel is the simplest and at the same time a very powerful version.
