Woops, typo, I'm a 7th Kyo, not 8th. Too late at night =P ^_^
First off, you dont need to make 3 separate posts. USE THE EDIT BUTTON. Sheesh.
Secondly...You know there is a huge difference between a distraction and a feint.
The act of distracting or the condition of being distracted.
A feigned attack designed to draw defensive action away from an intended target.
A deceptive action calculated to divert attention from one's real purpose.
Though a feint is a form of distraction, a distraction is not necessarily a feint. You seem to be making a lot of these type of mistakes. A pear is a fruit, a fruit is not necessarily pear.
A metsubushi is a distraction, so they quite easily could say distraction. Did they actually say feint? Was it translated? There are errors in translation, or misinterpretations. Qi can be literally translated as air and breath. If then every time the word Qi is mentioned by a Chinese person it is translated as air, a lot of mistakes can be made. If they explain that it is their Qi which allows them to protect their body, it may come out as breath, and seem strange. Or it is the cultivation of their Qi which lengthens their lifespan, which comes out as the cultivation of their air. o.O
It is quite possible a similar thing occurred. There are so many explanations. Maybe he did mean feint, or maybe he was just explaining metsubushi.
Hatsumi himself has even explained metsubushi, so I find it hard to believe that he would be saying it's just a feint, as that contradicts what he's been saying in the past.
Or, on the other hand, you could be making it up. Because I've seen a video of him when he demonstrated Ku while utilizing some dirt he had picked up off the ground. He said that metsubushi is a distraction, that can be done in many ways, from simply drawing attention with your hand (perhaps a way of saying a feint?) to actually using objects such as powder.
There are so many ways to explain your video. Assuming it even occurred. I couldn't make a proper judgement or explanation without seeing it. After all, "the metsubushi of void kata was explained as a distraction/feint...there was no mention of throwing stuff" hardly explains the video accurately.
I've never read Glenn Morris, but online I've briefly heard of his opinions of Kuji In as "a complete fallacy" or something of that sort. I've read on multiple places that he says it's just a myth that may have stemmed from basic meditation and mudras without any real extra purpose, and is just a fake belief. *shrugs*
I've never heard of that elemental breathing stuff you explained. We use standard breathing where it is all balanced at a steady pace. Sometimes we've incorporated what I can best describe as visualizing. It's not really imagining stuff, but kind of thinking about it in a way. For example, for Ka as we draw back into jumonji (not sure if you do that) after the block, we kind of imagine (not really physically imagining or anything, it's just a brief flicker of it, hard to explain) fire bursting around us and then being like a flame as we come through with the ura shuto. Sort of like that. Or with Sui, kind of incorporating the idea of drawing back like the ocean draws back from the sand, and then crashing in like a wave with the omote shuto. Other then that, it's just standard breathing with the movements.
there is also different ways of moving associated with these 5 elements...and the sanhsin no kata are by no means to be left as a straight line drill...no not directly linear...
they can also be taken and changed by using different kamae and body movement/footwork
Essentially the Sanshin No Kata can't be altered as such. There are combat variations, but you don't take the standard kata and decide "No, I don't feel like moving this way during Sui, I think I might come in at a different angle." It doesn't work that way, because the footwork, angling and dynamics are the exact reason why Ninjutsu doesn't require strength, and can all be performed by a relatively weak person. If you adjust the footwork, you make it difficult to perform the technique, if you change the angles of the technique, it might not even work at all. There ARE technique variations - ones which can be used in combat more, etc - but you wouldnt just change things around for the sake of it. Doesnt work like that.
