Although there is black and white, those are two sides of one coin, the absolute and the relative. And there is also some difference in the Rinzai and Soto way of practice. Soto puts emphasis on this one [white], and Rinzai puts emphasis on this one [black]. So Rinzai puts emphasis on enlightenment, and we put emphasis on each part of the body that participates with the practice of the absolute. So, that is why we are concerned about the mudra and posture and every form or manner of your activity.
