traveled to China to seek out what he believed to be a more authentic Buddhism.
He remained there for five years, finally training under Tiantong Rujing,
an eminent teacher of the Chinese Caodong lineage.
Upon his return to Japan, he began promoting the practice of zazen (sitting
meditation) and wrote some books about zazen. Fukan zazengi and Bendōwa.
He eventually broke relations completely with the powerful

the establishment, left Kyoto for the mountainous countryside where he founded
the monastery Eihei-ji, which remains the head temple of the Sōtō school
today.

famous work, the collection of 95 essays called the Shōbōgenzō, but also Eihei Kōroku,
a collection of his talks, poetry, and commentaries, and Eihei Shingi, the
first Zen monastic code written in Japan, among others.
