The Dojo Rules are usually posted at the front of the Dojo. They are recited either at the opening or the closing of class (or both) depending on the Dojo. The Dojo recites its rules, in hopes of making all those attending or listening better people in general, both physically and mentally. While each person may not have the same exact belief or definition for each rule, this ritual is meant to instill a positive ideal in each person hearing it.
Typically the most senior student in the class recites one line, which is then repeated by the entire class until the progression is ended. Through the practice of Karate, the discipline of the body and mind, and the reciting of the rules we become better people, of higher nature, and better in contact with ourselves.
