To think that practice and enlightenment are not one is a non-Buddhist view. In the Buddha-dharma they are one. Inasmuch as practice now is based on enlightenment, the practice of a beginner is itself the whole of original enlightenment.
Dōgen’s non-dual formulation dissolves the instrumental view of practice as preparation for a subsequent goal, asserting instead that authentic practice is itself the complete expression of realization.
