Every student of Karate should know and follow their Dojo Kun. Taken literally, "Dojo Kun" refers to rules inside the training venue. However, it is expected that students do not limit themselves to practising within the dojo. They are highly encouraged to practice the values they learn in the dojo to their daily lives. After all, Karate is a way of life that strengthens practitioners physically, mentally and emotionally. As such, the Dojo Kun is recited at the end of the class after Mokuso (meditation).
