Shitao(:tJ11) suggested that the one stroke of painting is the beginning of the Universe. he claimed that the one is the foundation of all the images. It is based on the DaoJ! that is erupted myriad creatures. His theory of one stroke is showing the root of the world and mind of artists. His theory is a mind theory of mind as well. As a Korean painter, I would like to explain my painting by the Shitao's theory of one stroke. It is painted by natural color from pine tree to draw the pine tree. It is claimed that one stroke is displayed by the way of seamless from the material to art.
