"Suzuki often cited the work of Japanese Zen monk Sengai Gibon (1750–1837), whose painting Circle, Triangle, and Square he saw as the embodiment of the universe. Suzuki interpreted Sengai’s three fundamental forms as geometries of formlessness and infinity, which underscored his own view of emptiness as the essence of Zen enlightenment. This scroll has fascinated people ever since. Rather than a single level of black or gray, the ink tones keep changing. The forms overlap just a bit, suggesting interconnections between these fundamental shapes."
