Hey, Attention on Deck!

Hey, NOTHING here is PERSONAL, get over it - Teach Me and I will Learn!

When you begin to feel like you are a tough guy, a warrior, a master of the martial arts or that you have lived a tough life, just take a moment and get some perspective with the following:

I've stopped knives that were coming to disembowel me

I've clawed for my gun while bullets ripped past me

I've dodged as someone tried to put an ax in my skull

I've fought screaming steel and left rubber on the road to avoid death

I've clawed broken glass out of my body after their opening attack failed

I've spit blood and body parts and broke strangle holds before gouging eyes

I've charged into fires, fought through blizzards and run from tornados

I've survived being hunted by gangs, killers and contract killers

The streets were my home, I hunted in the night and was hunted in turn

Please don't brag to me that you're a survivor because someone hit you. And don't tell me how 'tough' you are because of your training. As much as I've been through I know people who have survived much, much worse. - Marc MacYoung

The content surrounding the extracts of books, see bibliography on this blog site, are also mine and mine alone therefore errors and omissions are also mine and mine alone and therefore why I highly recommended one read, study, research and fact find the material for clarity. My effort here is self-clarity toward a fuller understanding of the subject matter. See the bibliography for information on the books. Please make note that this article/post is my personal analysis of the subject and the information used was chosen or picked by me. It is not an analysis piece because it lacks complete and comprehensive research, it was not adequately and completely investigated and it is not balanced, i.e., it is my personal view without the views of others including subject experts, etc. Look at this as “Infotainment rather then expert research.” This is an opinion/editorial article/post meant to persuade the reader to think, decide and accept or reject my premise. It is an attempt to cause change or reinforce attitudes, beliefs and values as they apply to martial arts and/or self-defense. It is merely a commentary on the subject in the particular article presented.

If people won’t like it, they won’t read it, but I won’t lose anything by it. Provided I don’t break any laws (libel, incitement to violence, etc.), I can post whatever I want. This means that I can write openly and honestly, however controversial my opinions may be. It also means that I could write total bullshit; there is no quality control. I could be biased. I could be insane. I could be trolling. … not all sources are equivalent, and all sources have their pros and cons.

“You should prepare yourself to dedicate at least five or six years to your training and practice to understand the philosophy and physiokinetics of martial arts and karate so that you can understand the true spirit of everything and dedicate your mind, body and spirit to the discipline of the art.” - cejames (note: you are on your own, make sure you get expert hands-on guidance in all things martial and self-defense)

Kinkotsu [筋骨] (Chinkuchi [チンクチ])

The characters/ideograms mean, “Muscles (sinews) and bones; structure.” The first character means, “Muscle; sinew; tendon; fiber; plot; plan; descent,” the second character means, “skeleton; bone; remains; frame.”

The term, “kinkotsu-ryuryu [筋骨隆々],” means, “muscular; strong-muscled.” The first character means, “Muscle; sinew; tendon; fiber; plot; plan; descent,” the second character means, “skeleton; bone; remains; frame.” the third character means, “hump; high; noble; prosperity.” 

Both theres terms are related to the Okinawan term, in Uchinaguchi or hogen dialect, “Chinkuchi [チンクチ].” Mr. Ryan Parker provided the following definition that relates better to the simple definition of bones, sinews, tendons, etc. Even the definition in its simplest form does not relate exactly to the definitions found by my research, i.e. tendons, muscles and bones.” Structure is somewhat limited as a variety of fundamental principles of martial system apply to the concept of chinkuchi or kinkotsu. Still the way Mr. Parker describes is really a good way to explain this concept to a student, i.e. “It refers to the last instant before contact is made when the skeletal structure becomes correctly aligned, all the agonistic muscles are very suddenly and sharply contracted, and the muscles which stabilize the relevant joints are engaged to an appropriate degree. It differs from kime in that it doesn't involve all muscles equally and depends on structural alignment and stability from connective tissues.

When you look to the fundamental principles you also find the following related or inter-connected to this more terse definition especially since they describe the totality of the actions required to achieve chinkuchi. 

When you refer to the primary principle of theory you can see that “control” is one because it is control of the body, mind and spirit with emphasis on the physiokinetic and technique principles that result in its proper application. Then (these should be self-explanatory) there is the efficiency sub-principle, power paradox, simplicity, natural action to start. 

When you look to the primary main principle of physiokinetics you then get the following sub-principles that are necessary, at the least, to achieve true chinkuchi, i.e. breathing, posture, centerline, spinal alignment, axis, structure, heaviness/relaxation, wave energy, convergence, centeredness, body-mind, centripetal and centrifugal forces, sequential locking and relaxation, and rooting. This is not to say the other sub-principles are not important as it is well known to achieve a total proficiency of chinkuchi it takes a inter-connectedness and wholehearted application of all principles but these stand out when it comes to the chinkuchi concept.

Also, taking a look at the main principle of technique we can see how economical motion, active movement, positioning, angling, complex foces, live and dead energy, speed, timing, rhythm, balance, natural and unnatural motion as well as extension and penetration also contribute to that which is called chinkuchi. 

As to philosophy and its sub-principles there are several that speak out louder when studying the practice of chinkuchi (come on folks, you don’t think I am going to provide all the answers. Even so, these are not compete either and should prompt further research and study).

As can be readily perceived the fundamental principles play an important role in explaining the concept beyond the limited definitions provided by the Japanese terms and characters/ideogram provided. This is another reason why it is important to find a sensei who can understand all the concepts, principles and applications that contribute to one another as an inter-connected wholehearted whole that are martial arts.
