Hakuin enso and Daruma
Here’s a delightful enso by the Rinzai Zen master Hakuin Ekaku Zenji (1686-1769). Unassuming and unaffected yet not at all reticent, it displays an exceptionally even and steady hand, with only a hint of the beginning and end at bottom left.
As a bonus, here’s a Hakuin Daruma, which reveals some of the same qualities.
