First, I would like to warn anyone who doesnt like my post to ignore this post, if it is not fit your taste, please do not read it.
Reading the above post from YKW give me an indication of some reader doesnt know what I am talking about.
So,
I like to make clear what is the 2 doors, snake engine, 6 direction vector force, 20Ch in a very layman term and common sense.
2 universal door
if you take a investigation on Advance Internal Chinese martial art training from ancient to present creation, all over china, Be it
the Shao Lin's Yi Jing Jing (Alter Sinews),
Shao Lin's Xi SUi jing (Bone marrow washin),
Shao Lin's Bo Dong Xing ( in move able heart)
Emei 12 Zhuang,
Wu Dang's Tai Ji,
Six Healing Sound,
Xing Yi's San ti shi
Yee Chuan's Zhang Zhuang.
Disregards of how their external shape from these system are
One will find two common universal common denominator or basic of the basic --- that is Loose and Silence.
That is the two doors I am referring. It is not my invention but a common denominator which is needed to attain before any of the above training could start and have result.
Loose is just a biomechanical handling so that one be able to sense, diagnostic, de-program/program one's physical handling.
Silence is just a Neuron handling so that one be able to aware, diagnostic, de-prgram/program one's neuron pattern.
Take power generation basic as an example,
The human's hip/thigh join, the waist/spine, the shoulder join coul be view and a four wheel drive car, with the hip/thigh is the two back wheel, the waist/spine as the transmission shaft, and the shoulder join is the two front wheel.
Now, in the power generation or Fajing. These three parts has to be sync and handling in a different way to produce different type of Jin.
In order to carry out the above, one needs a body which one has a accurate, precise, effective, and efficient handling.
So, All the above TCMA art listed rely on the Door of Loose to go to each section of the body to know it to work at it and to condition it differently depend on each individual style's need. No matter how different their stye are their all has to enter from the Door of Loose. Otherwise the physical work cannot be done properly. By passed this step will be similar to those who think they can Fajin but doesnt have a clear handling between the hip/thigh join and waist/spine because those part is a big piece which is stuck together, so Fajing in that case is muddy and sluggist and it is not effective and efficient at all but lots of brute force.
Now Take the example of perfom under Pressure as most always said can you do it under pressure.
The human mind is an computation and execution machine. This machine in general for the untrain is running on automatic. It chats, It run into stuck shutdown or freeze the physical body/ breating in Trauma, run into tunnel vision when force concentration.. ..etc.
if one cannot slow it down and lead it with Awareness or conciousness which is behind the mind. one has no control of it.
So, Chinese when design the above List of training knows, in order to do the physical body job, one needs to have a handle of the mind. and thus, slowing down the mind or leading the mind in a clear direction is the Silence training.
That is the Door of silence.
We often heard about in the old time one needs to practice stance for 3 months prior to punching. That three months is to have the Two Doors training. However, most lost this part of the training and most who train in it doesnt know what they are training is about. Standing in the stance get stress out or force the mind to patient. ... etc. getting torture similar to in the Shaw's brother Kung Fu movies is not the way of the training, it is a missed leading in fact great. and due to there is no result slowly and gradually one doesnt do those type of standing in stance training any more in these days.
But, see what is missed? the whole fundation is totally missed. and how can one has a decent kung fu when one jump from kindle garden to College without knowing how to add? it is a totally mess.
Now, these two doors got nothing todo with Zen, Dao, Chinese Culture, Religion, Dao de Ching saying...... etc it is purely Biomechanics and Neuron programming training aim to handle and alter and evolve one's mind-body.
Missing this point is missing the whole thing. Some keep argue with me and even call me a narrow minded...... etc. Well, disregard of open minded or close minded or narrow minded or broad minded. if We dont satisfy the mind and body nature or the Biomechanics and Neuron mechanics it simpy doesnt work. That is the bottom line.
So, the SLT/SNT how is the SLT/SNT training will make any sense if it is not entering these two doors? That is the question for every WCner.
Snake Engine Training
What is a snake engine training?
Imagine you have coil spring like this
http://www.google.com/products/catal...w=836&bih=465#
Snake engine training is just said, EVERY section of the sping needs to be unsync and move together accordingly so that there is no weak link and it could produce the best optimum result when it is compress or bounce... or pull.....etc.
Remember Your BJ set which is teching the concept of holistic unity Body structure and dynamic?
Snake engine training is BJ set's "back bone" supporting the execution of the BJ set concept and dynamic's operation.
6 Dircetional force vectors
Take the Coil spring above.
In a three dimensional space, I coil spring in the automobile suspension system will face the shock from the left-right, up-down, forward -back ward direction with all of the combination of these direction.
So, to be a coil spring in the suspension system, the coild spring better be able to sustain and handle all the different direction and combination of different directions.
Similarly, any point of ones' structure has to be able to do what the coil spring does. otherwise it will break down.
Now, looking at the snake engine training and the six directional force vectors. it just said the body and structure is train and condition similar to a coil spring for handling all different condition which is in the 3 dimensional space.
20 Channels of Qi flow medirians coverage
Qi flow can be think as hydraulic system of the mechanical system
the 12 normal medirians channel coverage is for handling the hand/feet action syncronized root-unroot with the breathing coordination
the 8 special medirians channel coverage is for handling different direction of motion, displacement and/or angling.
IE: Ren Du medirian is handling the forward and backward motion.
So, the above are clearly a biomechanical and Neuron system technology which is independent with religion, spiritual, culture.
All These stuffs is in a totally different realm with solo training it is actually an instantaneous handling training.
