A circle is born in the space, and people walk through the circle.
The light circle is a perfect circle without distortion. Even if you walk forward a few steps, the circle will remain perfect.
A calligraphic work in Zen, enso (a circle drawn with a single stroke) has since ancient times been written with canes or sticks in midair. It is said to represent enlightenment, truth, the entirety of the universe, and equality. The circle also reflects the hearts and minds of those who view it, with its interpretation left to the individual.
