Ensō (円相) is a Japanese word meaning “circle” and a concept strongly associated with Zen. Ensō is one of the most common subjects of Japanese calligraphy 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” it is often considered a form of minimalist expressionist art. In Zen Buddhist painting, ensō symbolizes a moment when the mind is free to simply let the body/spirit create. 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.
