SHUHARI
From Ohtsuka sensei's book "Wado Ryu Karate":
In martial arts, there is a word - "shuhari" - that has always existed. It also seems to exist in Japanese tea ceremonies and I do not know from which it was born.
"Shu" means to maintain the teachings of the predecessor and strict adherence to them; "ha" is to doubt anything that serves to disrupt that action. "Ri" is to be separated from the first two and improve on the teachings whenever possible. This not only applies to martial arts, but other disciplines as well. However, it is difficult to actually master any teaching - never less then five or ten years and varies upon the natural ability of the individual.
Besides, even if one is talented, serious training requires a lack of food or sleep sometimes - some things not possible for people in modern society. It is redeeming, however, to see that certain groups and organizations have recognized and honored those individuals who engage in "Shuhari" in whatever disciplines they maintain.
