Shoshin Nagamine quotes:

Karate-do is definitely a martial way, and its identity lies in do or principles. Any martial art without proper training of the mind turns into beastly behavior.

Karate-do may be referred to as the conflict within yourself, or a life-long marathon which can be won only through self-discipline, hard training, and your own creative efforts.

Even after many years, kata practice is never finished, for there is always something new to be learned about executing a movement.
