Triangle, Double Lock, Single Lock


In today's Practical Method practice in Toronto, we covered the triangle, double lock and single lock. Ketong Lin wrote an excellent article on this topic: http://dqstaiji.cn/archives/11907
Double lock means truly not moving the point in the 3D space. The solid line means that the two points are physically connected, while the dotted line represents that two points are not physical connected (there is as if an invisible line connecting them).

 
Figure 1
 

By creating a double lock at point A and C, and forcing point B towards the invisible link, we turn an "A" into an "Arch". Points A,B,C can present different parts of the body, e.g. Shoulder-Elbow-Hand, Foot-Shoulder-Hand. Right Foot-Dang-Left-Foot. For the Right Foot-Dang-Left-Foot case, this is how we make a dang rounded as supposed to be pointy.
Figure 2
 

Single Lock means the point is allowed to move along a specific direction, like running on a train track. By turning point C from double lock to single lock, and point B towards the invisible line, point C will shoot out along the A-C line. Let's use A-B-C for shoulder-elbow-hand as an example, the hand is squeezed out while the shoulder does not move.
Figure 3
 

Consider the following mapping:

A - Right Foot
B - Right Knee
C - Right Kua
D - Right Shoulder
E - Left Shoulder
F - Left Elbow
G - Left Hand
In order for the shoulder not to move, it needs support from other triangles, so the left hand can find a connection to the ground for the true support. Each invisible line is a rod/stick that we need to realize in our bodies. Essentially, with this concept, we can create a triangle with any points having 2 solid sides, and 1 invisible side. Instead of using the E-F-G triangle, we can use the C-E-G triangle.

 
Figure 4
 

Earlier we talked about turning an "A" into an "Arch". Figure 4 shows the S-Curve (Taiji Symbol). It also shows that our internal actions (color arrows) are different from what the opponent will perceive (black arrows). Often in reality, we are affected by our opponent's actions, and we lose these internal actions as soon as contact with the opponent is made. We need to train enough such that we can maintain these actions regardless of what happens externally.
