Re: Kamae vs Shizentai (hips underneath)
Why should it be unique?
Surely it is just a tool to allow a decent centre of gravity, posture and focus. Someplace comfortable and secure for us to learn from - like a good chess opening. Just because some use the Queen's Bishop and others open (hehehe) with the King's Pawn doesn't mean they are not both doing the same thing.
Were all boxers/grandmasters/chefs/teachers the same?
As is said again and again by everyone here...correct principles create correct technique.
As all the old masters die we are getting to the stage (it seems) where people deify the teaching methods. They are the tools not the goals.
Water does not have a shape unless it is in a vessel.
I'm not saying anything negative btw
