If you practice pulsing all the joints in the body, with a partner and on your own, many aspects Taijiquan will come to life. This is considered an original qi (yuanqi) practice because it is really obvious that babies do joint pulsing all the time. Most people loose much of this pre/post-natal action as they mature.
The wonderful thing is that this buoyant mobility is recoverable, even at advanced ages, because it relies on fluids not muscles. (Of course older people loose fluids as they age too, but not as fast as muscle.)
From a fighting point of view joint pulsing really amps up one's ability to hit with a lot of force using very little movement, and no wind up. In other words, fajing.
On the down side, there is a tiny delay in between opening and closing the joints that can be exploited by a fast and sensitive opponent. So if you want to reach the top level, you will eventually have to phase out the pulsing.
Here are the 6 stages of becoming a joint pulsing superhero:
- Make the joints open, make the joints close.
- Make the joints close, let the joints open. (the second part is passive)
- Make the joints open, let the joints close.
- Put opening the joints inside of closing the joints, and put closing the joints inside of opening the joints.
- Dissolve the closing and opening of the joints.
- Dissolve the intention to open and close the joints.
