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

Creating Your Own Dojo

In a recent article by Jesse Encamp, the Karate Nerd, he states in the lead, "When Should I Leave My Sensei and Start My Own Dojo?" Now, that is one loaded question and the short answer would be, "It depends!"

This can go back several lineages of Sensei such as his or her sensei to sensei's sensei to "sensei's, sensei's, Sensei," all the way to the guy who created the particular instance or style of karate. Let me say this, as a trained Marine Instructor as well as an experienced Teacher, Trainier and Leader both as a Marine and as a Sensei there are FEW who actually have the training to teach, not instruct, but to teach, mentor and lead.

Second, I used to say no one should attempt teaching, without direct hands-on guidance from a QUALIFIED teacher, trainer and mentor before reaching the grade or level of San-dan. Why? Because seldom have I seen or experienced a testing criteria that includes those traits one must have, believe and exude in the way they walk, talk, teach, train, mentor and actually live daily the life of a true teacher. 

As an example, here are some traits of a true teacher one must embrace and utilize to properly teach anything let alone karate as self-defense or self-fense. READ HERE

I am going to get a lot of flack here but there are few who are qualified to teach karate and that is just the way of it because it is too deeply engrained in the community and systems to believe and accept and therefore change. As a qualified instructor and knowledgable teacher, mentor and leader I stopped hands-on teaching about a decade ago because I was just not perceiving, seeing and believing that what I was using to pass on my knowledge and experience as actually effecting the end results and there is that I got older, maybe wiser and since I focused on the self-fense of karate felt there were aspects that needed a more experienced qualified teacher like those who actually lived a certain life style or worked a certain discipline that required such experiences. 

As to the San-dan requirement I stopped preaching that one because no one would listen simply because their sensei said their sensei did it this way and we should not change it type rhetoric. That is a true buzz killer don't you know. 

So, to answer the question should I step off to create my own dojo remains to be answered with, "It depends!" Just because you have a black belt; just because you hold a high grade or level of achievement as represented by your belt; and just because everyone did it this way so it must be correct DOES NOT MEAN YOU CAN TEACH; DOES NOT MEAN YOU ARE TRULY A MASTER; DOES NOT MEAN YOU ARE QUALIFIED to teach karate. 

Here is the final rub, if you have to ask, "YOU AREN'T QUALIFIED" so keep working hard and then one day, you will know that you are ready. Meanwhile, if your dojo and sensei are not passing on teaching traits similar to what I presented in the link above and a whole lot more seek out and learn how to be a great teacher, mentor and leader and start exuding it in your attitude and personality while training, practicing and living the life of karate in and out of the dojo. 

OT: Pandemic Layered Safety

What is layered safety? It is the same as layered security where one provides multiple security concepts that interlock and independently maintain a security posture, environment and protection that increases the difficulty of someone gaining entrance to a secured valuable location, etc.

Layered safety is based on this principle where multiple measures are taken that by themselves only provide a limited safety zone of protection while a layered model takes three or more measures that when layered take up the faults of each layer ensuring that the person is safe. In this case, the layered safety measures of the Pandemic. 

  • First, individual attitude toward social safety.
  • Second, mask-up 😷, any face covering will do it.
  • Third, distancing of six feet.
  • Fourth, avoid close spaced environments except as “required!”

The first layer is protection from others as well as protection of oneself from the virus gaining entry into one’s body in amounts that would result in infection, hospitalization and possible grave long-term harm including the possibility of death. 

It must be remembered that one’s attitude determines how well and to what degree one takes to protect themselves, their families, their loved ones that includes friends and associates, and others (being society in and of itself as a collective). 

A positive attitude of empathy and morality and ??? of self leads to the same feeling and attitude toward others who make up the fabric of our society.  It is the only way for our species to survive especially under attack from “Nature Herself” in the form of a dangerous virus. Someone once say, “The meek shall inherit the Earth,” and to our perceptions something like a microscopic virus feels meek in it nature even when it is deadly. 

Wearing a mask properly is very difficult and this is why they use layered health and safety requirements as you already see herein so all masks when layered with other health and safety measures creates a layer of safety that makes it “ALMOST” impossible to be infected and, even in an asymptomatic state, to infect others. 

You see, to ensure masks to the entire job is a social public way is literally impossible so layering makes perfect sense. As a former, retired, physical security manager for a very large institution the only was to ensure security is by the layered approach. It works the same in this medical pandemic situation. 

Wearing the mask therefore must have other measures to ensure the entire spectrum of possible infections are caught before they infect. That brings us to the next measure or layer.

Distancing alone, as with masks, will not do it either so if you think maintaining six feet means you don’t have to wear a mask, think again. The mask cannot completely and comprehensively keep our breath and what it carries out of our bodies from passing easily the six foot distance (rule). The mask stops some and the mask slows down the energy and speed necessary to go the distance, the six feet, so that together the two pretty much ensures those who adhere to the rules or layers or measures have a solid chance and ability to avoid infection. This brings us to one of the main ways infections are happening, big time!

The fourth layer is about avoiding closed in spaces that have little or now air circulation to pull air from the space and to pull in fresh air into said space taking any particulates out of the space. Them we limit the number of folks in that same space and hopefully those will allow are in that groups “bubble” of relatively safe folks to be around. Regardless, wear the mask and try hard to maintain six foot distance. 

Here again, the first layer comes into play because our attitudes must be of such a positive empathy oriented state of mind that keeps our diligence high so we don’t inadvertently in the moment drop our guard, or our layers, to expose ourselves at levels that lead to infection. 

There are more layers of safety for the pandemic like I mentioned about the “bubbles of safe-folks” we include and socialize with so we don’t suffer from “cabin fever” so to speak. This is critical because with the long-term need to remain diligent in maintaining our layered safety zones having some measure of meeting our needs, socially, must exist, it is about species, your, survival, right? 

Now, i just threw this all together so that some, who may not realize how important layered safety is in the pandemic, might come to realize that regardless of how we feel as to how it personally effects the life style we live, it means survival of us all socially, morally and being alive to enjoy life, now and in the future - especially for the future. 

Now is the time to be smart. When I was asked about my mask and being a fearless Marine (as if being a fearless Marine gives me some special protection) why would I wear a mask? I answered, “Marines are FEARLESS, but we are NOT STUPID!”

Taijutsu 体術

(たいじゅつ, ​taijutsu): unarmed martial arts (i.e. karate); a classical form of martial art. The first character/ideogram means, "body; substance; object; reality; counter for images," and the second to, "art; technique; skill; means; trick; resources; magic."

As you already know, this term is more apropos to the meaning of modern karate than martial art, bugei, budo or any of the many other terms used. First, karate is unarmed in nature. Second, it is and is not a martial art as that is defined. Third, it is an unarmed skill comprised of techniques that make up the multiple principled-based methodologies used to achieve protection and defense against grave harm and the resulting violence up to and including death. 

Karate is not about weapons, kobudo, but weapons are often taught along side karate in karate dojo throughout the world. Taijutsu is more appropriate in use for those who practice, train and teach karate for self-protection for self-defense in these modern times because today they hold less actual combative concepts due to both social and legal laws, mandates and requirements all meant to preserve and ensure the very survival of our species. 

This classical form is more of an older traditional concept so today's modern concept would be more in line with "practical" applications. 

The other characters/ideograms used are [體術] that translate to, "the body; substance; object; reality," and "art; technique; skill; means; trick; resources; magic." 

NOTES: On the Concept of Ikigai!

Ikigai [生き甲斐] translates into English to mean, "something one lives for; purpose in life. The first ideogram/character translates to English to mean, "life; genuine; birth," and the second translates to mean, "armor, A grade; first class; former; instep; carapace," the third translates to mean, " beautiful; patterned.

Did you know, like karate, the concept of Ikigai comes from the Okinawan culture? “ "The word "ikigai" is usually used to indicate the source of value in one's life or the things that make one's life worthwhile." AND "iki (生き) meaning life; alive" and kai (甲斐) meaning (an) effect; (a) result; (a) fruit; (a) worth; (a) use; (a) benefit; (no, little) avail" AND "the word is used to refer to mental and spiritual circumstances under which individuals feel that their lives are valuable."

"Have you ever been so absorbed in a task that you forget to drink and eat? What type of task was it? Notice those moments when you enter flow, and your ikigai might be embedded in those moments."If you’re a karate enthusiast, then you have to visit Okinawa—the birthplace of both ikigai and karate! There are over 300 dojos (schools) for you to perfect your roundhouse kick. There’s even a famous bar dedicated to karate with rare memorabilia, exhibits and plenty of Japanese whisky.”

  1. Stay active;
    • do what you love and if you are doing something else then learn to love that too.
  2. Take it slow;
    • pace, rhythm, cadence, etc., all related to setting patterns that keep you in the moment of every minute of life. Think Zen (See rules at end of article/post). 
  3. Don’t overeat;
  4. Good friends; 
  5. Healthy and fitness;
  6. Smile and be grateful; (tenacity and gratitude)
  7. Stay connected with nature; 
  8. Gratitude for everything;
  9. Be in the moment;
  10. Follow your ikigai!

Kokyuu [呼吸] translates into English to mean, “breathing; respiration; harmony; balance; synchronization; accord; knack; trick; secret (of doing something).” The first character/ideogram translates to English to mean, “call; call out to; invite” and the second translates to mean, “suck; imbibe; inhale; sip.” 

All the above traits or concepts that help us to understand what it takes to achieve a “state of ikigai” you will find that balance is involved. To be active; to take things in stride, to have friends, to eat in a balanced way; to remain fit and healthy, to achieve a state of mind that produces gratitude and a smile, to be one with nature; to be in the moment… Ikigai… means to balance them all in such a way as to achieve harmony with all nine concepts in a way that induces an enlightened, harmonious and natural way of being and doing in-spite of all those things that would induce imbalance. 

12 Essential Rules of Zen

  1. Do one thing at a time. This rule (and some of the others that follow) will be familiar to long-time Dojo practitioners who sit zazen mokuso meditative practices. It’s part of the martial arts philosophy, and it’s also a part of a Zen practice: single-task, don’t multi-task
    • When you’re pouring water, just pour water. When you’re eating, just eat. When you’re bathing, just bathe. Don’t try to knock off a few tasks while eating or bathing. 
    • Zen proverb: “When walking, walk. When eating, eat.”
  2. Do it slowly and deliberately. You can do one task at a time, but also rush that task. Instead, take your time, and move slowly
    • Make your actions deliberate, not rushed and random. It takes practice, but it helps you focus on the task.
  3. Do it completely. Put your mind completely on the task
    • Don’t move on to the next task until you’re finished. If, for some reason, you have no choice but to move on to something else, try to at least put away the unfinished task and clean up after yourself. 
    • If you prepare a sandwich, don’t start eating it until you’ve put away the stuff you used to prepare it, wiped down the counter, and washed the dishes used for preparation. Then you’re done with that task, and can focus more completely on the next task.
  4. Do less. A Zen monk doesn’t lead a lazy life: he wakes early and has a day filled with work. However, he doesn’t have an unending task list eitherthere are certain things he’s going to do today, and no more
    • If you do less, you can do those things more slowly, more completely and with more concentration. 
    • If you fill your day with tasks, you will be rushing from one thing to the next without stopping to think about what you do.
  5. Put space between things. Related to the “Do less” rule, but it’s a way of managing your schedule so that you always have time to complete each task. 
    • Don’t schedule things close together — instead, leave room between things on your schedule. That gives you a more relaxed schedule, and leaves space in case one task takes longer than you planned.
  6. Develop rituals. Zen monks have rituals for many things they do, from eating to cleaning to meditation
    • Ritual gives something a sense of importance — if it’s important enough to have a ritual, it’s important enough to be given your entire attention, and to be done slowly and correctly
    • You don’t have to learn the Zen monk rituals — you can create your own, for the preparation of food, for eating, for cleaning, for what you do before you start your work, for what you do when you wake up and before you go to bed, for what you do just before exercise. Anything you want, really.
  7. Designate time for certain things. There are certain times in the day of a Zen monk designated for certain activities
    • A time for for bathing, a time for work, a time for cleaning, a time for eating. This ensures that those things get done regularly. 
    • You can designate time for your own activities, whether that be work or cleaning or exercise or quiet contemplation. 
    • If it’s important enough to do regularly, consider designating a time for it.
  8. Devote time to sitting. In the life of a Zen monk, sitting meditation (zazen) is one of the most important parts of his day
    • Each day, there is time designated just for sitting. This meditation is really practice for learning to be present. You can devote time for sitting meditation, or do what I do: I use running as a way to practice being in the moment. 
    • You could use any activity in the same way, as long as you do it regularly and practice being present.
  9. Smile and serve others. Zen monks spend part of their day in service to others, whether that be other monks in the monastery or people on the outside world. 
    • It teaches them humility, and ensures that their lives are not just selfish, but devoted to others. 
    • If you’re a parent, it’s likely you already spend at least some time in service to others in your household, and non-parents may already do this too. 
    • Similarly, smiling and being kind to others can be a great way to improve the lives of those around you. Also consider volunteering for charity work.
  10. Make cleaning and cooking become meditation. Aside from the zazen mentioned above, cooking and cleaning are two of the most exalted parts of a Zen monk’s day
    • They are both great ways to practice mindfulness, and can be great rituals performed each day. 
    • If cooking and cleaning seem like boring chores to you, try doing them as a form of meditation. 
    • Put your entire mind into those tasks, concentrate, and do them slowly and completely. 
    • It could change your entire day (as well as leave you with a cleaner house).
  11. Think about what is necessary. There is little in a Zen monk’s life that isn’t necessary
    • He doesn’t have a closet full of shoes, or the latest in trendy clothes. 
    • He doesn’t have a refrigerator and cabinets full of junk food. 
    • He doesn’t have the latest gadgets, cars, televisions, or iPod. 
    • He has basic clothing, basic shelter, basic utensils, basic tools, and the most basic food (they eat simple, vegetarian meals consisting usually of rice, miso soup, vegetables, and pickled vegetables). 
    • Now, I’m not saying you should live exactly like a Zen monk — I certainly don’t. But it does serve as a reminder that there is much in our lives that aren’t necessary, and it can be useful to give some thought about what we really need, and whether it is important to have all the stuff we have that’s not necessary.
  12. Live simply. The corollary of Rule 11 is that if something isn’t necessary, you can probably live without it
    • So to live simply is to rid your life of as many of the unnecessary and unessential things as you can, to make room for the essential. 
    • Now, what is essential will be different to each person. For me, my family, my writing, my running and my reading are essential. 
    • To others, yoga and spending time with close friends might be essential. 
    • For others it will be nursing and volunteering and going to church and collecting comic books. 
    • There is no law saying what should be essential for you — but you should consider what is most important to your life, and make room for that by eliminating the other less essential things in your life

Funakoshi Sensei said ...

Funakoshi Sensei said, “Karate is like boiling water. If you do not heat it constantly, it will cool.” 

Comment: Although, for his time this may have had a meaning that today does not quite fit because to keep a pot of water on a rolling boil will simply evaporate in time and I don’t think that was his meaning, at all. If we keep at a certain level of effort our skills will improve so tending to that effort is similar to tending to one’s garden. All flora, trees and other plantings if continually tended to with watering, plant foods and removing all the weeds tends to help them grow and flower over time. Even this has its limitations but will not diminish its flowering until its natural end of life much later as any good Gardner already knows. 

Mass Oyama Sensei said, “One becomes a beginner after 1,000 days of training. One becomes a master after 10,000 days of practice.” 

Comment: In its day it assumes, as it would even today, that one knows that there is much, much, much more to it than simply training and practicing any number of days. A beginner actually begins the day they walk through the dojo doorway. The beginner begins to build on that by what they do, how they do it and how they participate, listen and understand that which is being trained and taught by he or she who comes before, as in experience, etc., i.e., sensei and/or senpai. To master any skill is not just about repetitive practices over a certain time span because some can master a skill in a period of time much less that that which would accumulate days up to and surpassing 10,000 days. Here again, what is being practiced matters more than merely passing the days in some form of practice that can be repeating a move vs. repeating, learning, understanding and practical application of said methods over time. Then how many hours in a day, how many days a week and how many weeks per year also matter because to embed such things in the mind also require certain concepts and skills to make them work vs. simply dancing to the tune of the sensei and dojo. Think about this. 

In closing, in lieu of keeping the water to a boil, I would rather the student keep the water at a low simmer, not to hot and not cold, so as to allow it to flourish over time much like the gardener tilling the soil and tending the plantings. 

As to those days, dedication of any number of days with the natural void or empty space in between tends to build a stronger foundation than putting in the same amount of energy and effort and expending both daily for such long periods of time. Like music if you don’t allow space, void, between the notes you will find the music disappears and all you get is noise. Build those skills, etc., over proper time and tending to the flames to keep a steady simmer rather than a boil. It matters.

The Misconception and Misunderstanding of Karate

Blog Article/Post Caveat (Read First Please: Click the Link)

First example: The chambering of one's fist to the waist.

Second example: The technique of blocking.

Third example: Stances, especially the assumption of same to perform a technique.

These three examples were drawn from this most excellent article by the "Karate Nerd." You can read his article here: 3 Widespread Misconceptions of Modern Karate

The purpose of borrowing his idea’s of chambering, blocking and stances is not about his article but merely a borrowing of the subjects themselves for a different perspective on misunderstandings, etc., in the karate world or communities. 

Also, a take-away from this article is this one is my theories, opinions and beliefs so take those with a grain of salt and use this, and others, as a means of thought - like my “Karate Koans” effort. To inspire, to trigger one’s creative juices and to diverge from the accepted norm that what sensei teaches is complete, comprehensive and exclusive to mastery of the system, style or methodology. Ok, on with the show!

First example: The chambering of one's fist to the waist.

I have written already extensively on this subject so, if you please, take a trip to another link provided and get in some reading. Note, that this link also has two more links embedded within so don’t forget to read them all BECAUSE they build on one another for an overall perception and outlook on this technique or method. It must also be noted that many of the so-called ‘bunkai’ of this method were created to fit it as taught originally by the creator of Isshinryu, Shimabuku Tatsuo sensei. It teaches us that just because it is a teaching does not mean we bend to it accordingly but rather we bend the physics, theory and method/methodology to fit its true purpose in teaching us how to protect and defend through a teaching tool the skills, outside of it, to actually get-r-done. 

Second example: The technique of blocking.

First and foremost, as taught to the novice, blocking is a misnomer. It is a particular movement meant to teach us how to handle oncoming forces such as an attacker coming at us in a moving attack. You see, blocks are meant to be expanded and diverged from to create a movement I call, “deflection-movement.” You begin the deflection move while moving one’s body off center-line to deflect that attack method while positioning yourself in a way that allows your methods to be triggered while taking you off their attack line so they literally fly by you opening points along off center and around to the side and then to the back as dictated by circumstances and effects of the entire methodologies - theirs and yours. 

Here is another article I wrote on the subject of blocking, take it with a grain of optimism and as you already know, a supplemental methodology meant to enhance what you were taught by your sensei, etc. 

Third example: Stances, especially the assumption of same to perform a technique.

This one is also of great length as was the first example. So, as I did the first, the third has an article with sub-links within it you may find of interest on the stances of karate. Go ahead, enjoy them then come back here to read the conclusion. 

Read Here: On Stances of Karate

As you already know from your vast experiences and expertise there is plenty to seek out and understand from the very novice level explanations to those you will discover over your years and years of training, practice and experiences. 

The real lesson to learn is this, there is no one single correct answer or teaching in the world of karate be it sport, philosophical or hands-on self-protective defense methodologies because otherwise we would go to a few classes then just practice once in a while to learn what there is to learn. In truth, there are no limits to learning in regard to karate or any other discipline or knowledge but only the limits we put on ourselves so go out and learn, learn, learn (just like “practice, practice, practice!)!

Ikken Hissatsu [一拳必殺]

Blog Article/Post Caveat (Read First Please: Click the Link)

It has been said that to have Ikken Hissatsu, one must, "execute every blow, punch, strike, kick, etc., with intent, the attitude of 'this will be the final blow.' Always expect the first blow to be the last, but never rely on it." 

PERSPECTIVE (Enkin-hou [遠近法]): When translated, the term in English comes to mean, somewhat, the following: 

  • "to annihilate at one blow"
  • "it conveys the spirit that the karateka (player) must partake in"
  • “kill with one strike”
  • “one punch kill”
  • (ichi) meaning “one” , (ken) meaning “fist” and hissatsu meaning “certain kill or death”
  • "to annihilate at one blow"
  • "single strike that ends the contest"
  • "one fist, certain kill,"
  • "to beat with one strike"

Ok, you get the point. It must be remembered that such old meme's although presented with the best of intentions sometimes don't carry over in modern times for a variety of reasons. In these modern times, i.e., late 2020, such meme's when taught and followed regardless of its explanations can and do leave open perceptions and judgements especially when it comes to their effects in self-protection for self-defense. 

It sets the mind-state of the uninitiated, even those who assume they know, a certain attitude that can transcend true self-protection for self-defense into a concept of deliberate aggressive intent thereby putting the person into the illegal side of self-defense rather than a justified legal and acceptable side and view of self-defense defense. 

Let's divide karate, for instance because that is where these meme's are used the most, into "sport" vs. "protection in defense." In sport, taking the initiative to win a match is pretty clear that we are not actually annihilating another human being toward grave harm or death, but in self-protection for self-defense society, in general, along with both social and legal systems WILL use such things to get the win, a guilty verdict regardless of whether you actually were defending yourself over being an mutual participant or the actual aggressor. There are some who are doing time because of this distinction so make sure you address it in your training LOOOONG before you use those skills in "protection for defense."

If the meme does not promote and instill a proper attitude in training that attitude will rise to the top like cream to the top of milk when the stress hits along with an adversary coming to do you harm. This matters!

"IF the opponent leaves an opening, you have to take it right away, 100%." 

PERSPECTIVE (Enkin-hou [遠近法]): First and foremost, don't get me wrong because I am NOT putting these meme's down but I AM advocating that one teach toward an understanding of how they applied historically and how they should be applied, explained and understood all depending on what your focus is in taking karate or any martial discipline, i.e., "Solely Philosophical (kind of self-help thing); Solely Sport (for the fun of competition, camaraderie and inclusion); solely for self-protection in self-defense against grave harm or death?" 

If sport, when you can score the point or get that knock out. In self-protection it gets really complicated because of use of force issues along with the social and legal system mandates, requirements and laws. If philosophical, go for it because in that instance as long as it does not bleed over into self-protection for self-defense you can do pretty much anything morally and legally acceptable in a social way. 

"Why, shouldn't the sensei explain all this stuff to the students?"

PERSPECTIVE (Enkin-hou [遠近法]): Yes, yes, and yes, but, as to those who drop by and see these (online and without sensei)  it is important to explain to them so they don't mistakenly understand that which must be understood. Then there are those sensei who preach, teach and promote things as self-defense who literally have no clue and allow their students to go out and use their skills, think "Kobra Kai, not the series but the movie versions."
