The following was written by Ueshiba Morihei, founder of Aikido.
He might have not have been training Karate, but please try to see it from a bigger perspective.
1. The original intent of Bujutsu (martial arts) was to kill an enemy with one blow – since all techniques can be lethal, observe the teachers directions and do not engage in contests of strength.
2. Bujutsu is an art in which the one is used to strike the many. Therefore train yourself always to be mindful of, and alert to, opponents in the four and eight directions.
3. Always train in a vibrant and joyful manner.
4. The instructor can only impart a small portion of the teaching. Only through ceaseless training can you obtain the necessary experience allowing you to bring these mysteries alive. Hence, do not chase after many techniques – one by one make each technique your own.
5. In daily training, begin with basic movements to strengthen the body without overexertion. Spend the first ten minutes warming up and there will be no fear of injury even for older people. Enjoy yourself in training and strive to comprehend its’ true purpose.
6. Training in Bujutsu is to build ones’ character. The techniques are transmitted from person to person on an individual basis and should not be disclosed indiscriminately to the public. Such secret techniques should not be used for evil purposes.
