THE DOJO KUM

Dojo Kun (the karate code)
Karate has a dojo kun which is basically a set of guidelines for karetekas to follow both in the dojo (a room in which karate is taught) and out of the dojo, in a kareteka's everyday life.

1 Seek Perfection of character

One: To strive for perfection of character
Two: To defend the paths of truth
Three: To foster the spirit of effort
Four: To honor the principles of etiquette
Five: To guard against impetuous courage
