The Enso (Japanese for 'circle') is a Zen symbol of the absolute, the true nature of existence and enlightenment. It is a symbol that combines the visible and the hidden, the simple and the profound, the empty and the full. As an expression of infinity, it has links to the western lemniscate, and may be painted so that there is a slight opening somewhere in the circle, showing that the Enso is not contained in itself, but that it opens out to infinity. The enso, a simple circle drawn with a single, broad brushstroke, is the zen symbol of infinity. It represents the infinite void, the 'no-thing,' the perfect meditative state, and Satori (enlightenment.)
