This mentality of “I must resist” can be an obstacle to learning how to flow and react in a timely and appropriate manner.
When you first learn from a teacher you give resistance because you want to see if he has the skills you want to learn.
But down the road if you continue to resist for no other reason than you end up retarding your learning. We must remember learning is learning and not competition. When you work with your teacher he is feeding you movement, feeling, energy to teach you how to move.
So when you resist you end up not learning what he is trying to teach you. Thus, for example if you resist and run away from a simulated attack that’s all you did. If your teacher did not press the attack then you thought you got away with it. If he pressed the attack then you end up resisting more and not learning how to respond better. If the attack is faster you might end up getting struck many times and not see where the attacks came from.
The lesson to remember when learning is LEARN, not resist for the sake of resisting. There is a time to resist and there is a time not to do so. When learning to be pushed if you try to resist you end up getting pushed harder. If you can let go and tell yourself to enjoy the push you will become like the Daruma doll that cannot be pushed over. Like I said before the skill is already in you. You just have to let it out. To resist is to keep your natural skill imprisoned and prevent you from progressing.
