Ch: Xiangyan Jizhu. Also read Kōgan gekichiku. A painting subject of the Tang dynasty Zen 禅 (Ch: Chan) priest Chikan's 智閑 (Ch: Zhixian) sudden enlightenment upon hearing the sound of bamboo being struck. Chikan, sometimes called Kyōgen 香巌 (Ch: Xiangyan) after the name of the temple where he lived, was a disciple of the priest Izan い山 (Ch: Weishan) at the Kyōgenji 香巌寺(Ch: Xiangyansi) in Dengzhou 鄧州, modern day Henan 河南. Izan, although recognizing Chikan's potential, was unable to help him achieve enlightenment. One day, accordingto the Mumonkan 無門関 (Ch: Wumenguan, 1229), while visiting the ruined temple of the earlier patriarch Echū 慧忠 (Ch: Huizhong) in Nanyang 南陽, Chikan took up a straw broom and began to clear away debris near a bamboo grove. Suddenly he heard the sound of something (his own broom by some accounts) striking a stalk of bamboo and instantly attained enlightenment. Kano Motonobu 狩野元信 depicted the subject in one painting from his set of Zen patriarchs, Zenshū soshizō 禅宗祖師像 at Daitokuji Daisen'in 大徳寺大仙院, now Tokyo National Museum.
