The Absolute

 Enso circle by famous early 20th century priest and Daruma heir to Nantanbo,

Kutsu Deiryu

Ensō  is a Japanese word meaning "circle" and a concept strongly associated with Zen. Ensō is one of the most common subjects of Japanese Caligraphy even though it is a symbol and not a character. It symbolizes the Absolute, enlightenment, strength, elegance, the Universe, and the  void; it can also symbolize the Japanese aesthetic itself; as an "expression of the moment".

In Zen Buddhist painting, ensō symbolizes a moment when the mind is free to simply let the body/spirit create. The brushed ink of the circle is usually done on silk or rice paper in one movement (but the great Bankei used two strokes sometimes) and there is no possibility of modification: it shows the expressive movement of the spirit at that time. Zen Buddhists "believe that the character of the artist is fully exposed in how she or he draws an ensō. Only a person who is mentally and spiritually complete can draw a true ensō. Some artists will practice drawing an ensō daily, as a kind of spiritual exercise. (wiki definition)
