Only by "cutting through" one's desire to obtain what they want, can one be freed to accomplish their true destiny.
As we experience in martial arts training, successful results depend more on our ability to maintain composure and respond effectively to a situation than the speed and power in our physical techniques.
The "live" blade insists on awareness, focus, and concentration without pause. There is no room for the thoughts and distractions of our desires to bind us. With the sword we learn to cut through the illusions and desires that often lead us to lose our way. All that becomes obvious is the true path.
Once on that path, the energy generated by our connection with our "sword and self" enables us to proceed more efficiently toward realizing our true potential.
