The true science of martial arts means practicing them in such a way that they will be useful at any time, and to teach them in such a way that they will be useful in all things.
Miyamoto MusashiEven if you strive diligently on your chosen path day after day, if your heart is not in accord with it, then even if you think you are on a good path, from the point of view of the straight and true, this is not a genuine path. If you do not pursue a genuine path to its consummation, then a little bit of crookedness in the mind will later turn into a major warp. Reflect on this.
