The practice of Small Chi Sphere is related to the practice of the Elongated Wrist. In actual learning, we may not learn in this order. Instead, we typically learn other main principles such as the Three Chi Rings, Lowering the Elbows, Buns Under the Armpits, etc before we come to the Small Chi Sphere.
I touched on it here because the Small Chi Sphere principle is an extension of the Elongated Wrist principle. The easiest way to learn the Small Chi Sphere and make it a habit is by learning to do it when your hand is in open palm formation.
This is simplifying and dumbing down the actual process of learning to use the Small Chi Sphere but if the objective is to pick up the understanding earlier, well I suppose it is a necessary evil.
You learn about the Small Chi Sphere by learning to hold it between your fingers when you have an open palm formation. All five of your finger tips gently grasped and adhere to the Small Chi Sphere. You need to use your imagination to do it.
If you are lacking in the visualization department, get an actual small, ideally light ball, and have a feel of what it is like to grasp it. This is a quick way to get the feeling. There are limitations to learning this way but if its gets the learning moving along then why not.
Whether your palm is facing down, facing up or facing forward, always have the Small Chi Sphere grasped between your fingers. Never lose it unless the learning steps call for it to be momentarily out of your hands.
When you can grasp the Small Chi Sphere, then you can learn to manipulate it. A very simple basic manipulation occurs in the Beginning Posture where you are holding the Small Chi Sphere with your palm down, then release the sphere to fly through the air into the distance, then as you turn your palm up the sphere flies back into your hand in a quick instant (the action is performed by hold hands, eaching holding its own sphere).
Right before this action, there is an action of how each of the two spheres is formed, rolled up the body, inserted through your body, then brought back out before releasing and retrieving the sphere.
And after this, you again insert the spheres into your body, bring them out, place them on the level surface of the river (it can also be the sea or a swimming pool, but let’s make it a river) and press the spheres into the water, right up to the Kua Ring of the Three Chi Rings.
By now, you can see how easily complicated the learning has become and we are still in the Beginning Posture movement. I just described it to give you an idea of what our learning of GM Wei Shuren’s Tai Chi is like.
Along the way, you can learn to manipulate the Small Chi Sphere by rotating it, depressing it, dashing it, and even disintegrating it on cue from an external pulsing dot. Yeah, man, some of the things we do sounds just like science fiction when we describe it.
There are so many more things to talk about when it comes to the Small Chi Sphere. I think I will give my hands a rest from the typing and your mind a rest.
