Thank you for viewing. Tenkoku (Seal Carving) Play Seal/Leading Seal "Enso" (Circle) The circle, also known as "Ichienso" (One Circle), represents the ultimate form of the universe. It is said that the five elements that are the origin of all things – space, wind, fire, water, and earth – can be expressed in a single stroke as a circle. It is said that the circle most concisely depicts the myriad things, the entire universe, and the ultimate form of the world.
