Enso 

"Enso," by the Japanese Zen monk Sengai (1750-1837), is a simple yet powerful ink-on-paper painting. The artwork features a single, bold circle, known as an "enso," a symbol of enlightenment and the universe in Zen Buddhism. It is a quintessential example of Zen art, emphasizing the beauty of emptiness, spontaneity, and the artist's inner state of mind. The surrounding calligraphy adds another layer of meaning to the work, enhancing its profound nature. The enso, created with a single, continuous brushstroke, is a testament to the Zen philosophy of finding perfection in simplicity and the pursuit of inner peace.
