Kendo is unique among sword arts as it requires a complete spirit, sword and the body unison when attacking. This may seem odd since one with no training in kendo can just slash and even kill an opponent with the same motion and a similar sword. Ki-Ken-Tai-Ichi is translated as “spirit, sword and the body as one” generally the meaning is the perfect cut, the perfect cut encompasses how one approaches a match. Kendo is really a systematic method of instantly defeating an opponent, it takes into account the utter fear one faces in an actual life or death match. In a life or death match our first untrained and natural response is for self preservation at all costs. One with no training in kendo will lack either the spiritual, mental willingness to attack or physical prowess to attack, and such an attack will be a random disconnected effort. To practice kendo correctly fear and doubt such as one faces in keiko must be overcome. Overcoming fear and doubt can also be called courage. It is only by casting away the fear of loss or death that one is able to win and live. The lesson of Ki-Ken-Tai-Ichi a complete spirit, mind and body attack can not be overlooked when practicing.
