Tetsugyu Doki (鉄牛道機)
Doki TETSUGYU (August 25, 1628 - October 2, 1700) was a Zen priest of the Obaku School in the early Edo period. His Go (pen name) was Jibokushi. His shigo (a posthumous name) was Daijifuo kokushi. He was born in Nagato Province (some assert that he was born in Iwami Province).
After conducting ascetic training at Ryuho-ji Temple in Inaba Province (Tottori City, Tottori Prefecture), he practiced Zen meditation under the guidance of Ryuki INGEN, who was then staying in Nagasaki City, and was involved in the foundation of Manpuku-ji Temple. After that, he studied under Shoto MOKUAN, a leading disciple of INGEN, renamed himself Doki TETSUGYU and succeeded Mokuan's teachings. He endeavored to spread the teachings based on the philosophy of the convergence of teachings and Zen meditation, strove for the construction of Manpuku-ji Temple on Mt. Obaku in Uji, restored Kyoto Rakusei Hamuro Joju-ji Temple and founded Odawara Shotai-ji Temple in Sagami Province and Kofuku-ji Temple in Edo. He cooperated with Doko TETSUGEN in the publication of 'Daizokyo' (the Tripitaka) and also lent assistance in social work such as the reclamation of Tsubakinoumi sea in Sosa-gun of Shimofusa Province. Upon the request of people, he later constructed Fukuju-ji Temple (Tosho-machi) (Tosho-machi, Chiba Prefecture) near the place where Tsubakinoumi had been located, and died there.
