Insight: the second-to-last thing that went through the poor fellow’s head… You know, right before the bokken!
Understanding the moment is something that happens outside the moment. It is something that takes you away from the moment. The bokken is a hard, wooden practice sword used in some martial arts practices, including Aikido. The intensity of weapons practice should bring the practitioner into full awareness of this very moment. Any distraction may create an opening and lead to his end.
But, understanding this is in itself one such distraction.
