It is a principle of the art of war that one should simply lay down his life and strike. If one's opponent also does the same, it is a even match. Defeating one's opponent is then a matter of faith and destiny.
Yamamoto TsunetomoBe true to the thought of the moment and avoid distraction. Other than continuing to exert yourself, enter into nothing else, but go to the extent of living single thought by single thought.
