Practice and realization are one

Dogen's teaching that practice and realization are one, shusho ichinyo, denies a claim most religious training assumes without stating: that practice is a means to a separate end called enlightenment, arrived at once the practice has done its work and then set aside. In his essay on pursuing the way, Dogen writes that to think practice and realization are not one is a view outside the Buddha's own teaching, and that in the authentic transmission the practice of the way at the very outset is already the whole of original realization, so that a beginner's single period of sitting is not a lesser or partial version of a master's, but complete in the same sense the master's is. Modern scholarship on Dogen ties this claim to his rejection of a widespread medieval Japanese Buddhist idea called original enlightenment, hongaku, which had come to treat awakening as an already possessed status needing no practice at all; Dogen's own position sits deliberately between the two extremes his critics accused him of, neither treating practice as a ladder to a distant goal nor treating it as unnecessary because buddhahood is already secured. The doctrine has a direct practical consequence recorded in Soto training: a monk is not ranked by how many years of sitting stand behind him, since a fresh period of shikantaza is held to actualize the same completeness Dogen ascribes to his own long practice.

Because Soto teaching holds that realization is not a future state practice earns but the character of practice itself, the school extended shikantaza's logic outward into ordinary monastic work, a principle usually named samu, so that cooking, cleaning and manual labor performed in a training monastery are treated as full practice rather than chores that make time for the real practice of sitting. Dogen wrote a separate set of instructions for the monastery cook explicitly to make this point: preparing meals with full attention is not a lesser task assigned to those not yet ready for the meditation hall, it carries the same shusho ichinyo claim the sitting cushion carries. Scholars of medieval Japanese Buddhism read this move as Dogen's practical answer to the original enlightenment doctrine debated across the Tendai school of his own training background, in which awakening could be affirmed as already present without any activity actually changing, a position Jacqueline Stone's study of medieval Tendai calls a live and contested current in the Buddhism Dogen inherited before founding his own school. Soto's insistence that the manner of ordinary activity itself carries realization, rather than only sitting alone, is the tradition's way of keeping practice and realization inseparable in daily life and not only on the cushion, since a doctrine that realization equals practice has nowhere to stand if only one activity in a monk's day counts as practice.
