Creating a shell around myself

Let's get to a more concrete example:
- Engage the opponent. Let's use the position where the opponent pushes into my elbow.
- Start with nothing moving (lock everything) with a right foot forward stance.
- Push the heel of the front foot against the ground and open the front kua. This allows the energy to come up the front leg and go across the front side of the waist.
- Push the ball of the rear foot against the ground and open the rear kua. This allows the energy to come up the rear leg and go across the back side of the waist.
- Stretch the central vertical rod, and make sure that it does not move.
- Step 2 and 3 will gradually cause the flesh around the vertical rod to move around the rod. This is like how to spin a rattle drum with two hands. This is the breakout part.
- Keep both shoulders down, and tie them to the kuas. This is part of creating the shell.
- Don't move the hands or arms. There is often a strong desire to move them, we need to resist the urge. This is also part of creating the shell.
- Point the middle finger of the front hand towards the opponent's centre. This is the aiming part for the controlled release.
- At the end, nothing really moves. Only the energy is projected to the opponent.
