Dogen's Shobogenzo and the Unity of Practice and Enlightenment

The Shobogenzo, "Treasury of the True Dharma Eye," is Dogen's principal work and an unusual one within East Asian Buddhist literature for being composed largely in vernacular Japanese (kana majiri bun) rather than the classical Chinese normally used for doctrinal treatises, a deliberate choice enabling direct address to his Japanese monastic community. Dogen composed and continually revised its component fascicles from around 1231 until his death in 1253, and because he never assembled a single finalized edition, later manuscript traditions preserve differing collections — most widely, a ninety-five-fascicle Honzan edition, alongside older seventy-five- and sixty-fascicle groupings — a textual history that has significantly complicated modern scholarly editing and interpretation. Early fascicles composed at Koshoji, such as Bendowa (1231) and Genjokoan (1233), already lay out the work's central concerns, while later fascicles composed at Eihei-ji, including Bukkyo and Sanjigo, address monastic ethics and the workings of karmic cause and effect with markedly greater severity, reflecting a hardening emphasis on strict precept observance in Dogen's final years.
