Thank you for sharing your wisdom, opinions and experience concerning Tensho and breathing. I had pretty much dismissed the "folk tales" about Goju breathing techniques leading to strokes but I wanted to be sure since I am one of those individuals who does take BP medication.
Before I incorporated the practice of the form, I needed to be sure I wasn't putting myself in danger. The performance by Master Chinen appears to be "over the top" but hey, he has been doing this for decades and, apparently, has suffered no ill effects from the practice.
The other clips were instructive as they represented a spectrum of performance to which anyone could easily adapt.
Bill, I do wish to attend this year's summer camp, thus, I will take you up on your offer to work with me on Tensho - Imagine the faces of the kyu ranks when they see the instruction, thinking that they will have to learn it for promotion within Uechi - We'll have to put on an "over-the-top" performance just to make people squirm

Additionally, your explanation on breath, muscular contraction and BP was outstanding and intelligible (unlike those provided by typical Ph. D'.s and MD's).
Mr. Hawkins appropriately raised the issue of center line techniques. In my own experience, Uechi-ryu practitioners do not typically execute Sanchin strikes to the direct center. The target is typically just about where the index finger is targeted in line with the nipple. It appeared to me, that Mr. Chinen's performance demonstrated a punching target at lower than optimal striking height. To my Uechi eyes, the angle seemed "off".
Mr. Prouty, thank you for the delineation of the distinct breathing techniques to be found within the kata. This will be quite helpful to my own practice!
Max, my understanding is that Tensho develops the "hard" aspect of Goju not the soft aspect. I believe that advanced practitioners of the system would agree with this contention. Apparently, the breathing techniques develop an internal hardness as has been explained by Mr. Glasheen and Mr Prouty.
As to the origins of the form, who is to say? Legend is not fact. It is a fact that Goju and Uechi share a common heritage, including the relationship with Go-Ken-Ki. which is no surprise to anyone who is familiar with both arts, Obviously, this relationship influenced the development of both systems along similar paths.
All the best,
Mike DeDonato
