Zen Meditation (Zazen) is a particular kind of meditation, unique to Zen, that functions centrally as the very heart of the practice. In fact, Zen Buddhists are generally known as the "meditation Buddhists." Basically, zazen is the study of the self.
The great Master Dogen said, "To study the Buddha Way is to study the self, to study the self is to forget the self, and to forget the self is to be enlightened by the ten thousand things." To be enlightened by the ten thousand things is to recognize the unity of the self and the ten thousand things. Meditation has continued, from generation to generation. It spread from India to China , to Japan , to other parts of Asia , andthen finally to the West. It is a very simple practice. It is very easy to describe and very easy to follow. But likeall other practices, it takes doing in order for it to happen.
