This question cannot be answered accurately without showing us the kanji.

Kime in karate is not the same as kime in kendo or aikido.

And Fajing is NOT AT ALL related to kime.

You did not specify the art of the kata you are referring to.

When you practice karate kata, you do so with kime, which means FOCUS.

Decisiveness is an attribute of focusing. It is something you must intend to do.

When you are reverse engineering your kata, to extract application, you must do so with intention, but you have to consider that you are working with a partner, and you do not want to injure your partner. Still you must consciously work the technique slowly, and emphatically. You have to make sure that it has the effect you want to produce on your opponent. You try different variations and scenarios so you can use it no matter the position or whether sitting or standing, carrying groceries or your child, etc.

When you have the technique smooth and flowing, you increase resistance, speed.

But you can only do this to a certain point. You can cause injury to your partner.

This is where the practice of kata is superior. Once you have the technique flowing, you use full intention and FAJING - now that you have an understanding of what the technique means.

You never stop working your techniques with an uke, but you continue its development and making it a reflex by repetition with your uke and full power kata practice.

There’s too many words here, and too many people. Even though we have general agreement on the terms of the words, the exact meaning and feel of the words differs from person to person.

I think each move should be explosive and decisive. Full of intention, but without overpowering thus becoming hard and fragile. I think of it this way because not thinking of it as explosive might give room for my mind and body to relax and the power structure from the ground might be broken by this shaky relaxed foundation. At the same time thinking of it as being powerful is a trap in that it creates this rigid structure that can easily be unbalanced or shaken from another angle. I like to think of the words ‘with intent’, but the words encompasses the meaning of explosive, flexible, with focus, and more. And all of those meaning are not thought out, but felt as one meaning.

I think this matter is same as dao. You can't explain it in words because the words are vague and yet solid and the true way is ever shifting and yet clear. You can only feel it and have an abstract understanding of it, but when you try to give it a form the form becomes becomes something different.

That is a poor explanation of kata, and how do you ever come to a conclusion that it will wear you out.

By your example shadow boxing is even more worthless

A single kata has almost all of the techniques you need for kumite,

A single kata would take books to explain, just like any style would.

Can you explain your entire style in a single sentence. Can you put all the techniques, tactics, footwork, etc into a single paragraph. Without losing the essence if the style. No you can't, just like you can't with kata

Edit: your question was also about kata which I answered

Perhaps you should reread your own question or rewrite it

As for the kima part I'll answer that when I'm in a computer and when I don't have to deal with this dumb autocorrect

Awesome question! My instructors ALWAYS have us doing forms - as you say, "kime" or "fa-jing" - that is, where power is always expected.

That is why I have a difficult time in Aikido, where everything should be more about positioning and balance - and never about strength.

They say that "harder" styles get softer the more you become advanced in it; and "softer" styles get harder the more you become advanced in it.

For me, I've always done well testing and competitions when I've used power, speed, and dynamic tension. The appearance of strength, power, and concentration was always appealing to judges and outsiders. But, when we rely on force, the opponent cannot be easily led into a position of advantage to us because they will pull back. For this reason, a softer, gentler approach is more desireable.

Perhaps that is why harder styles become softer as practitioners realize this, and softer styles - practitioners knowing this, know when to apply harder techniques at the right moment.

Now, when I do my forms, I do tend to fall back to my old ways - which is fine for my instructors. But sometimes, I will do my forms with concepts of Aiki that I add in, and, the result is far less appealing to those who expect force, strength, speed - fajing.

And yes, I am often out of breath doing even basic forms. I tend to be very forceful and energetic in my forms. But whether I do them with force or with Aiki, I always consider the applications. These days, I am learning to try to balance both into my forms - generally, not to my instructor's liking. As I am a guest to several TKD schools, I tend to "do as the Romans do" and not make waves about how forms should - or shouldn't - be done. But when I practice at home, I change my MO regularly.

It should be done than praticed full contact no use doing it if you don't use it full contact. It shouldn't dominate lessons either there should be a healthily mix of kata and full contact/semi contact training.
