for those wondering about the six directional forces and the snake engine…
the six directional force vectors are present in every instant.
As a result, they describe motion and by extension, momentum at any instant.
Put together with the time component, then we are describing the trajectory of that momentum. As trajectory is the motion over time, from the trajectory then, we know the past momentum and thus it is included as well. When one is training the 6D force, when practiced with loose, silence, and nature, one will begin to be aware of those 6 forces (or combination thereof). With the awareness then comes the handling.
when balanced, then one is in levitation state. In levitation, one will begin to move naturally and experience true neutral. This is different than what some may call Relax or Loose. Being Relaxed and Loose are nice, but that alone is not enough to get one into Awareness. And often, one will think they are Relaxed and Loose except they are not.
thus if one is capable of handling the 6D in motion (dynamic), one should be able to take care of static as well. in Awareness one will become aware of the 6D force naturally as the body naturally expands in the six directions. when one part of the body moves, the whole body moves. Thus in the SLT, there is no such thing as only the arm moving during the punch or any other motion as the entire body is moving. The momentum generated in each motion then is also recycled and reused so that one does not have to start and stop or get stuck at some instant.
now in order to feel the Awareness over the entire body, one needs to be able to open or activate the physical body to allow the sensing and awareness ability to extend throughout the body. just being physically loose and relaxed will not cause one to be aware of the 6D because you also need the silence. so the snake engine gives one the ability to handle the 6D at a very fine granularity, from the fingertip to the toes. one needs both 6D and the snake engine in order to handle momentum dynamically at any instant at any kind of contact. without the snake engine, one cannot handle all the detail down to the smallest level. without the 6D, one cannot know how to handle the momentum.
so the 6D gives one the knowledge of how to handle the momentum and the snake engine gives one the tools to handle it down to the small details. thus when the sets are performed this way, one becomes aware of the details of the momentum in each motion and how the entire body is involved. this will cause movement or momentum in the body thus making it alive. as one becomes aware of the momentum, then one can start to see how via the momentum generators the momentum can be amplified or how the generators can be combined…which gets into fajin and hua jin…
