About Mujū

Mujū Dōkyō, birth name Ichien Dōkyō, was a Buddhist monk of the Japanese Kamakura period. He is superficially considered a Rinzai monk by some due to his compilation of the Shasekishū and similar books of koans, but there is good evidence that he was also an eager student of the Tendai, Pure Land, and Hosso sects, and he is occasionally placed in the Shingon and Ritsu sects as well.
