Ruth Strout McCandless studied at Stanford University and Claremont Graduate School and in 1941 began her association with Senzaki. In 1955, while under the tutelage of Soen Nakagawa at Ryutaku-ji, she became the first Western woman to stay at a Zen monastery. She was one of the editors of "The Iron Flute", a collection of ancient Zen koans with essays by Senzaki.
