In the sixth century a text named the Shinhinmei refers to the way of Zen as a “circle of vast space, lacking nothing and holding nothing in excess”. At first glance the ancient ensō symbol appears to be nothing more than a miss-shaped circle but its symbolism refers to the beginning and end of all things, the circle of life and the connectedness of existence. It can symbolize emptiness or fullness, presence or absence. All things might be contained within, or, conversely, excluded by its boundaries. It can symbolize infinity, the “no-thing”, the perfect meditative state, and Satori or enlightenment. 

Ensō symbolizes many more things including: strength, elegance, the universe, single mindedness, the state of mind of the artist at the moment of creation and the acceptance of imperfection as perfect. It also represents the oneness of life and all things contained within it, the spirit of harmonious cooperation, personal development and refinement of character, the visible and the invisible, absolute fullness in emptiness, simplicity, completeness, endlessness, perfect harmony, the circle of infinity and the cyclical nature of existence.
