Shigeru Egami quotes:

Even in the forty years that I have been practicing Karate, the changes have been many. It would be interesting to be able to go back in time, to the point when the kata were created, and study them.

The techniques should not be practised simply so they can be performed in the kata. Since karate is a fighting art each technique and movement has its own meaning. The karateka must consider their meaning, how and why they are effective, and practise accordingly

Through courtesy you will take a humble attitude toward your opponent in training & be grateful to him.
