Audi (& others),
I do not have the video that you refer to, so I can only guess at what Master Yang may be referring to with the ‘quick’ ‘short’ ‘simple open hand strike’ as an example of liejin. It is possible to apply torque to an opponent with a snappy one hand strike (e.g. bending the recipient backwards due to his feet remaining stationary) that may not manifest if done slowly (e.g. the recipient being able to step or root without being bent backwards – i.e. while maintaining their ‘central equilibrium’). Could this be what is being demonstrated? Done snappily the strike could perhaps produce liejin whereas the same application done more slowly may perhaps produce anjin instead?
Some people may have a clear understanding of one manifestation of one of the eight Taijiquan energies, and may attempt to extrapolate that as the definition of the energy without realizing that it is only one manifestation of that energy. So, for liejin, the whirlpool or flywheel analogies illustrate two possibilities for this energy, but may not define the energy. Both the whirlpool and the flywheel can produce torque, but so can other applications (e.g. Yang’s simple open hand strike).
A fairly common example of the problem of attempting to generalize a definition from the understanding of one example of that energy is when someone defines pengjin as upward energy. To me this is inaccurate and would be equivalent to someone seeing a ball bouncing along the ground and assuming that balls can only bounce upwards. Of course, we know that balls can bounce in all directions, and someone observing a ball bouncing in a racquetball game would not make that mistake. In TJQ we want to maintain energy in six (all) directions (up/down, left/right, forward/back) like a properly inflated sphere. But a TJQ practitioner is typically standing, and the ‘rooting’ provided by the feet against the ground typically provides the rebounding energy of the practitioner, thus the resulting energy is typically upwards. But to me, pengjin’s rebounding energy is not in itself restricted to upwards, but rather capable of manifesting in any direction. Although typically expressed upwards, pengjin is not restricted to upwards. For example, a TJQ practitioner with their back against a wall could peng outwards if using the contact between their back and the wall as their ‘root’ to rebound the energy from. Since we are not spheres and have articulated joints, we can also redirect the rebounding energy somewhat so that it does not necessarily rebound directly opposite the direction of the incoming force (or directly opposite the ‘root’) like it would for a spherical ball.
Since I have joined this thread’s discussion, I should also provide my understanding for caijin, zhoujin, and kaojin.
The typical contact points for TJQ are the hands/wrists (or feet), so to me, zhoujin is simply energy expressed through the elbow (or knee), and kaojin is simply energy expressed through the torso (shoulder, hip, chest, back). For ylsim this would be what ILC refers to as changes in ‘section’.
Since we are not spheres and have the ability to grasp objects, to me caijin is energy expressed through grabbing. To me this does not imply a specific direction as is often implied (e,g, ‘pull down’), although a downward direction is typical since the ‘root’ of our arms is the shoulder, and since our hands are the ‘tip’ of the arm, energy from the hand tends to start rather high through the shoulder and be manifested typically in a downward direction. If the term ‘pluck’ is used to translate ‘cai’, then it fits this non-directionality better since someone can pluck fruit from a tree in a downward manner, but also pluck a flower from below in an upward direction. To affect a recipient, a grab to merely hold them does not really convey the energy of caijin, so the action of jerking or pulling quickly is often used in describing this energy. But to me, the primary quality is the ability to grab.
