''Dogen Zenji, the great thirteenth-century master, regarded as the founder of the Japanese Soto School of Zen says: 'Practice and Enlightenment are not two.'
Reading this, many people believe that Dogen Zenji's Zen is a Zen that does not require an enlightenment experience. To state my conclusion first, such a belief is a mistake. I finally believe that the most important matter of Buddhism is to attain enlightenment.
The point by which Zen Buddhism is differentiated from other religions or philosophies and from all kinds of theories, is precisely this: the attainment of enlightenment."
