Sincere thought means thought of concentration (quiet awareness). The thought of a distracted mind cannot be sincere

The key to immortality is first living a life worth remembering.

Since life is an ever evolving process, one should flow in this process and discover how to actualize and expand oneself.

A good teacher can never be fixed in a routine... each moment requires a sensitive mind that is constantly changing and constantly adapting. A teacher must never impose this student to fit his favourite pattern; a good teacher functions as a pointer, exposing his student's vulnerability and causing him to explore both internally and finally integrating himself with his being. Martial art should not be passed out indiscriminately.

To me, ultimately, martial arts means honestly expressing yourself. Now, it is very difficult to do. It has always been very easy for me to put on a show and be cocky, and be flooded with a cocky feeling and feel pretty cool and all that. I can make all kinds of phoney things. Blinded by it. Or I can show some really fancy movement. But to experience oneself honestly, not lying to oneself, and to express myself honestly, now that is very hard to do.

Endurance is lost rapidly if one ceases to work at its maximum.

The more complicated and restricted the method, the less opportunity for expression of one's original sense of freedom.
