Dōgen

Dōgen Zenji was a Japanese Zen Buddhist monk, writer, poet, philosopher, and founder of the Sōtō school of Zen in Japan. He is also known as Dōgen Kigen, Eihei Dōgen, Kōso Jōyō Daishi, and Busshō Dentō Kokushi.
Originally ordained as a monk in the Tendai School in Kyoto, he was ultimately dissatisfied with its teaching and traveled to China to seek out what he believed to be a more authentic Buddhism. He remained there for four years, finally training under Tiāntóng Rújìng, an eminent teacher of the Cáodòng lineage of Chinese Chan.
Upon his return to Japan, Dōgen began promoting the practice of zazen through literary works such as Fukanzazengi and Bendōwa. He broke relations with the Tendai School and later left Kyoto amid ongoing tensions with the school. He eventually founded Eihei-ji, one of the two head temples of the Sōtō school, in present-day Fukui Prefecture.
Dōgen is known for his extensive writings like the Shōbōgenzō, the Eihei Kōroku, the Eihei Shingi, along with his Japanese poetry, and commentaries. Dōgen's writings are one of the most important sources studied in the contemporary Sōtō Zen tradition.
