After Bodhidharma, he was the eleventh successor[1] in the line of Nányuè Huáiràng (677–744) and Mǎzǔ Dàoyī (709–788), as well as—according to some sources—Línjì Yìxuán (although according to others he was Linji's contemporary).
Gutei spent his time alone in the mountains, meditating and chanting the Kannongyō, the twenty-fifth chapter of the Lotus Sutra.
The nun challenged Gutei to utter a word of Zen, but—when he proved unable to do so—she left.
Having spent so much time in meditation and study, Gutei became dismayed at his inability to say a single word of Zen to the nun.
Gutei realized that his inability to answer the nun was due to his lack of understanding, and asked Tenryū to teach him.
