Philosophical background
True creativity is not the product of consciousness, but rather the phenomenon of life itself. True creation must arise from “Mushin”, the state of no-mind, in which thought, emotions, and expectations do not matter. Truly skillful Zen Calligraphy is not the product of intense practice, it is rather best achieved as the product of the no-mind state, a high level of spirituality and a heart free of disturbances.
Circle is a symbol in Zen, which is painted in the form a circle in one stroke.
Understanding and truth, Buddha-nature, and the entire universe is symbolically represented by a circle, the interpretation of which is left to the viewer.
