Visualize a point in space. Fix it in your mind. Now point your left index finger at it.
Next, move your left index finger towards it. As you move let your left index finger pull your left arm and your left leg towards the target.
Keep moving your left index finger towards the point in space even as your left foot lands on the ground and you shift your weight from your right leg to your left leg.
At the end of the movement check if your left index finger is still pointing at the point or is it pointing somewhere else.
If you didn’t get it the first time try again and again until you get it. It is not a difficult thing to do correct or is it? How many tries did you go through before you got it. Did you get it within an hour or take a few days to get it?
If you did not get it what was the reason why you couldn’t get it?
Most of the time you would think you got it. So it is good to use a video or get a spotter to help you check if indeed you are doing what you think you are doing.
You may find it easier to actually hang an object for you to point towards. Try it if this is what works for you. Once you can do it with an object try going back to doing it without an actual physical object.
Most people who do this think they are able to point to the point in space when they fail to do so. It is easy to deceive ourselves to think we are doing what we are not.
To be able to do this simple thing you need to be able to keep your mind on your left index finger all the time first and foremost.
When you can do this then you need to assign some of this attention to the other parts of the body that is involved in the movement chain. All this while you must keep your mind still trained on your left index finger so that the entire body coordination is still whole.
You keep practicing until the entire movement chain is smooth outwardly yet on the inside you can feel how each part of the chain is moving in its turn in terms of changes in velocity, getting the relevant mass lined up behind each other in preparation to be able to trigger the mass to move sinuously like the rising and falling of a wave.
The better your body control the less outer movement you need to use, to the point where a slight downward movement will be like an ocean floor suddenly caving down to displace a body of water to create a tsunami, in this case an energetic wave consistent with rising (Peng) and falling (An) characteristic of an actual wave.
The movement in this experiment is the second movement after Beginning Posture that leads up to Grasp Sparrow’s Tail. Though this movement can be used to learn how to generate power, we must never divorce it from the application. If you do not keep the application in mind then what happens is that you will end up exaggerating the wave motion in an attempt to generate more power.
There is a trade-off between power and speed. In application we need to be timely when the need is there. If you are too slow to get into position then you will not be able to get into place to generate power. And when you get into position you have a split second to issue power before the opponent fights back.
So between speed and power you should go for speed because speed is basically a matter of change in velocity. The change in velocity is termed acceleration which is found in the formula for Force = Mass X Acceleration.
The form trains us to move in the manner of an imperceptible wave, controlling the rate of velocity and amount of mass that should be used in various techniques. Sometimes you need a hammer to do the job but sometimes you need to use a thumb.
Training the form is not about training fajing only. Training the form is training the use of techniques and understanding how various force models can be used with their attendant timing, angles, position, etc.
Training the form is the beginning of the study of the means to an end. Push hands is another piece of the study puzzle. When you have learned how to move like the wind, execute techniques like the falling of incessant autumn rain, pound with the force of a wave, and flow like a river then you can learn to apply the techniques more freely.
