Penetrating the Sphere: Geometry of Attack

Posted in I-Liq Chuan, Internal Arts, Techniques, Training with tags , , , on February 12, 2011 by mindbodykungfu

In a previous post, I discussed the point of contact in terms of vector components. When you penetrate your opponent’s sphere, you pass the diameter line of the virtual sphere at the point of contact and have technically passed your opponent’s defense. However, just getting past the diameter line is necessary but not sufficient.

One mistake that I frequently made (and probably still frequently make) is to roll and pivot past the diameter line and attack straight away. That tends to only work if you partner or opponent is not attentive to your actions. The problem arises from the fact the force interactions are multidimensional. The point of contact is not a static sphere; rather, it is a dynamic point that changes curvature and moves in space.

Just touching the other side of the diameter line only means you have entered the sphere of defense. It does not necessarily mean you have an appropriate application point. You can penetrate the sphere but still give your opponent enough space to recover as you attack. In essence, your opponent readjusts his sphere to intercept your attack and re-establish your contact outside of the sphere.

Point Of Contact

In my experience with learning and teaching I-Liq Chuan, I have noticed that a lot of time is spent training the point of contact.  Once the basic understanding of body unification is achieved, training can quickly progress to framing movements in terms of the point of contact.  The point of contact provides a context for movements and serves as a training aid which guides the training progression.

The way I usually introduce the the point of contact is as a physical link for coupling force into your opponent.  To affect your opponent’s structure (or control balance via the structure), you need a link to couple your force into your opponent.  The most straightforward way to do that would be to grab at the point of contact.  The coupling of force can also be done without grabbing.  The touch contact needs to align to solid structure (i.e. bone), and the body must unify to the point of contact.  When those two conditions are met at the point, usable force can be coupled into the opponent’s structure.

The nature of the point of contact is dynamic.  Outside of static demonstrations for teaching, the point of contact will be constantly changing.  This necessitates attention to the point of contact to perceive the present conditions at the point.  The act of focusing the attention to feeling and adapting to the changing point is itself training.  Like breathing in sitting meditation, paying attention to the point of contact is a mental focus tool during partner training.  Spinning to flow at the point is largely a mental exercise.

Probably most importantly (at least from my point of view as an instructor), the point of contact provides a feedback tool.  Whether a student understands body unification or movement applications can be felt from touch.  The same touch at the point of contact can be used to provide kinesthetic feedback.  Once the correct touch has been demonstrated and felt, the student has a diagnostic to gauge whether the body alignments and movement modifications are correct.  The point of contact serves as a training diagnostic for both the instructors and students to assess and correct alignments and movements.
