Miyun Yuanwu (Chinese: 密雲圓悟, pinyin: Mìyún Yuánwù; Japanese: 密雲円悟, Hepburn: Mitsuun Engo; 1566–1642) was a prominent Chinese Chan master of the Linji sect. Born in Changzhou, in modern Jiangsu Province, to a prominent family, and was educated as a Confucian.[1] In 1594, after reading the Platform Sutra of the Sixth Patriarch, he left his wife and children and immediately ordained under master Huanyou Zhengchua of Yuwang Monastery in Changzhou.[2] In 1603, his master left for Beijing and left him in charge of the monastery. At that time, he is said to have attained sudden awakening, and in the next decade became famous for his distinctive development of Chan teaching methods, reviving the "beating and shouting" of Linji.[3]
