Sensei Gichin Funakoshi's 20 Karate-Do precepts that he created and lived by.
Karate begins and ends with respect and courtesy
There is no first attack in karate
Karate supports righteousness
Know yourself first, then others
The art of the mind is more important than the technique
Free your mind
Trouble is born of negligence (and ignorance)
Karate is not just for the dojo
The training of karate takes a lifetime
Karate is like hot water, it cools down if you do not keep heating it
Do not think of winning, rather think of not losing
Transform yourself according to your opponent
The outcome of the fight depends upon the manoeuvre
Imagine one's arms and legs as swords
Once you leave home there are a million enemies
Postures are for the beginner, later they are natural positions
Perform the Kata correctly, the real fight is another matter
Do not forget to control the power and speed of a technique
Always be good at the application of all you learn
Apply the way of Karate to all things. Therein lies its beauty
