Good point, Chihua. The 20 precepts of Karate-Do are:
1- Karate Do begins an ends with rei (lit. bowing, also a sense of respect/self-esteem).
2- There is no first strike in karate.
3- Karate stands on the side of justice.
4- First know yourself, then know others.
5- Mentality over technique.
6- The mind must be set free.
7- Calamity springs from carelessness.
8- Karate goes beyond the dojo.
9- Karate is a lifelong pursuit.
10- Apply the way of karate to all things. Therein lies its beauty.
11- Karate is like boiling water: without heat it returns to its tepid state.
12- Do not think of winning, think of not losing.
13- Make adjustments according to your opponent.
14- The outcome of a battle depends on handling emptiness and fullness (weakness/strength.

19- Do not forget employment or withdrawal of power, the extension or contraction of the body, swift or slow application of

20- Be constantly mindful, diligent, and resourceful in your pursuit of the Way.
Great rules to train and live by. What strikes me is how many of these are found in martial arts, religions, and secular philosophies from around the world.
So how about it gang? Personal favorites? Funny anecdotes? Personal insight on a particular one? How about similar codes from the many styles and schools represented on this board?
Anecdote - My sensei uses 17 on us. He sometimes tells us to relax when we're sparring, or do a form however we want, and then will yell at us for doing just that. "DON'T DROP HAND WHEN SPAR!! YOU THINK YOU MASTER!?"
