Beginners are aware that all you need to win a match is to constantly attack. What they do not realize is this is just one of many strategies. Higher ranking kendoka will devise a different strategy to defeat you based on past matches. Talented kendoka can devise strategies on the fly, adapting and changing infinitely to the situation of the match. The level of devising strategies on the fly is clearly what true champions are able bring to a match.
I have often been puzzled by the seemingly contradiction of trying to rid oneself of the desire to win in order to obtain mushin, and how do you win without the intense desire to win? Mushin and Fudoshin are both a Buddhist, Zen tradition. The most famous zen master was the priest Takuan Soho, notable for his great wisdom and his famous followers. Takuan states in his writings that “without desire, nothing can be achieved” and “If you act on the basis of the unwavering right-mind, the energy of desire is transformed into the right energy. It is no longer called desire, it is named gi. GI is virtue.” gi means duty. Takuan goes on to say “If you shun desire and become like a rock or a piece of wood you can do nothing. With the help of the energy of desire one can transform desire (yoku) into no desire (mu-yoku). This is the true way.” Takuan’s words explain the samurai notion of the desire to win based on gi and not on greed or selfishness (material riches, or fame).
The kendo three methods of killing are: kill the sword (ken-o-korosu) meaning to move the sword off center, kill the waza (waza-o-korosu) meaning to spoil the opponents waza, and counter with your own waza, kill the spirit (ki-o-korosu) using seme to overwhelm the opponent. I believe there is a connection between the three methods of killing and the four poisons in kendo referred to as: fear, doubt, surprise and confusion. Using any of the three methods of killing instantly produces one or more of the poisons of kendo in your opponents mind giving you a good chance of victory.
