PUBLIC MARKS with tags budo & spirit

“In Iaido we always win against enemies” performing a kata slowly or quickly, result is the same … We win. Of course we are alone fighting against imaginary opponents and the scenario (Riai) says we win. How could we loose ? I did not deeply thought about this but writing it down suddenly gave me a strange feeling. Why should we be so sure (reassured) of the encounter result if we really live the kata, if we really live in the moment ?
