Sumi on paper. A fine ensō drawn by Reigen Eto, one of the most prominent disciples of Hakuin. It is said that Reigen was known for his delicate brush strokes and works that displayed a profound empathy with nature.
Upon the death of his original teacher, Reigen returned to the temple of his ordaining, Zensho-ji and shortly thereafter retreated to the mountains to live a simple life as a hermit. After many years, he once more took up training under Hakuin and several years later received the formal recognition of Zen’s deepest realization, inka.
