The Dogen Institute: “The Dogen Institute is the educational outreach arm of the Sanshin Zen Community. The Institute provides educational opportunities for all who are interested in the study of Dogen Zenji and his teachings. The primary mission of the Dogen Institute is to make available Shohaku Okumura Roshi’s life work on Dogen. Okumura’s translations, commentaries, and lectures will be offered through books, audio, video, and web-based materials.”
Glasgow Zen Group: This group has built an incredibly handy site that summarizes each of the Shobogenzo’s 95 fascicles (chapters). If you’re new to the Shobogenzo this would be a worthwhile pre-read.
