What is Fajin?

Master Chen has stated before fajin is everything is in the correct place, add speed. How do we add speed?

Physical examples:
  1. Shooting with bow and arrow. Release the arrow to reach the target. Most of the effort is in pulling the bow, and maintain the integrity of the pull, and aiming at the right place.
  2. Exploding like a bomb. We build a very strong shell for the bomb, and keep expanding the inside until the shell can't hold it anymore.
  3. Snapping the finger. The strong the initial holdback of the finger, the louder the sound.
Note that in all the above examples, it involves two opposing forces going against each other the best they can, and then there is the release, which is something that happens on top of the setup.

Recently, I had a couple of experiences:
  1. I locked the outside (hands and feet), twisted up my inside by opening my joints. Neighbouring joints opened in opposite directions. I then locked the inside, and let go of the outside. The potential energy that was built up inside was therefore allowed to be released out. This approach was an expression of separation of yin and yang (Lock the outside, move the inside; Lock the inside, move the outside).
  2. My opponent caught me between his right arm and right thigh. He swung his right arm around trying to knock me over.  He put quite a bit of power on me.  I tried to lock my centre by stretching vertically and redirect his power back to him. He was like bouncing off a wall, fell backwards, took a couple of steps, and ended up sitting on the ground.
For the first experience, I did work to build up some energy and release it, whereas for the second one, the energy originally came from the opponent, and was sent back to him.
