Enso 

"Enso" is a Japanese Zen Buddhist art form, created by Enji Torei (1721-1792), a calligrapher and painter. The artwork is a circle, representing the universe, painted with a single brush stroke. The circle is often called the "circle of enlightenment" and it represents the idea of wholeness, perfection, and the interconnectedness of all things. The circle's simple beauty allows viewers to reflect upon their own understanding of the world. The artwork also features a unique inscription, adding another layer of meaning to the piece.
