The Enso circle can be opened or closed, but they signify different meanings. An open Enso signifies an incomplete circle that is part of a greater good, the imperfection of human lives, and the circle of emptiness where the self flows in and out while it stays centered. On the other hand, the circle is described as a whole when it is completed and closed. It signifies perfection and points to the cycle of birth, death, and rebirth.
