As Chief Black Elk said, “Everything the Power of the World does is done in a circle.” Yin and yang, these complementary opposites are expressed in a circle. We live in circles within circles. The rotation of the Milky Way, the solar year, the seasons, solstice and equinox, the waxing and waning of the moon, the rotation of earth that gives us night and day, and birth and death. The circle of life, our life.
