They speak of "This Dojo" and "That Dojo". They are looking for profit.

If you want to learn the craft of war, ponder over this book. The teacher is as a needle, the disciple is as thread. You must practice constantly.

Imitation is the surest form of flattery and failure. I am not interested with your talk about my ideas. I am more interested in your applying them to your life. If you do not, then you are essentially not in accord with your own mind.

Even 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.
