About "Erasing Myself"
Let me add some explanation about erasing myself.
Erasing myself is a translated concept from Korean one, so it may not be understood easily at first. But I'd like to suppose an example in training.
In competition, it is difficult to catch a good chance, even though you can see it when you observe it from the third party's view.
It can be a tip to catch a good chance for attack that you kick or punch before you hesitation. Everyone come to think, and thus to hesitate before his try, because he tries to catch a chance that the opponent wants to avoid.
When I see and feel a chance and try, he also can feel it and begins move before I reach him. You should deceive yourself in order to deceive your opponent. In the same manner, you should precede yourself in order to precede the opponent. In order to precede yourself, you should move before your decision and your hesitation. But it is difficult. Because you intend to defend and to succeed in attacks. Thus you should give up. You should Erase every thought and every hesitation so that you cannot recognize your movement. When even you cannot recognize your movement it is impossible for your opponent to recognize it either.
What would lead your motion and attack, then?. Only your daily training. What you've trained, therefore, what you've put down in your mind even under your unconsciousness and under the bottom of your life will lead your natural motion which you cannot recognize that yet succeed in controling over the opponent.
It can be an understandig of erasing myself.
The part 2 of "That I clench my fist" implies this way.
