Think about the rods/bars that link the old kind of train’s wheels together. Those rods only ever go forward even those each wheel only rotates. This is yin-yang reversal. There is a joint in the middle of the wheel, there is another joint at the place where the rod is attached to the wheel. If there is no such joint and the rod is totally glued to the wheel, as the wheel rotates, the rod will also turn around with the wheel.
In reality, if we simply rotate a lever 360 degrees, the same side will go back. We must never go backwards with rotation. That’s why our circle is really an S curve.
The internal gongfu is to be able to convert rotation (wheel) into linear movement (rod), or linear movement into rotation (that’s how each piston in an engine works).
Exercise 1:
- Place the forearm onto a wall in front of my body.
- The load is on the fingers.
- The pivot is in the middle of the forearm.
- Move the elbow downwards, and the load will go up on the other side as long as from the finger tip to elbow is one piece.
- The elbow downward movement is independent of the lever setup. Our training is to ensure that the lever set up properly and never changes/buckles.
- The downward power is actually pushed into the pivot in order to go to the other side.
- In actual usage, only speed will allow us to create the pivot. In other words, the pivot will presents itself in speed.
Exercise 2:
- Just like firsts step of the first move for the left arm.
- Maintain the line between the finger tip and shoulder.
- Move the elbow underneath this line to go to the other side.
- This is a 3-dimensional move.
Dead object is even, and double heavy itself.
All movements must have a lead.
Drill bit
- The groove catches the outside, it makes a lever with drill bit as the pivot. Look at it from the front view of the bit.
- Without the groove, we cannot drill a screw in because there is no catch.
