Immature strategy is the cause of grief.

It is said the warrior's is the twofold Way of pen and sword, and he should have a taste for both Ways. Even if a man has no natural ability he can be a warrior by sticking assiduously to both divisions of the Way.

Whatever your determination or will power, it is foolish to try to change the nature of things. Things work the way they do because that is the way of things

The ultimate aim of martial arts is not having to use them

Unless you really understand others, you can hardly attain your own self-understanding.

When you cannot be deceived by men you will have realised the wisdom of strategy.

Accept everything just the way it is.
