Dan, just a quick question, do you know why Ueshiba allowed ukemi and showed the principles of aikido via techniques without teaching aiki first??? Or did he??
I don't think anyone knows.
Why did his teacher, Takeda only produce 5 great teachers?
Why did Takeda say not to teach white people?
Why are the Chinese famous for....not teaching?
We can hypothosize all day long. There have been a million words devoted to it for decades. Some will say Ueshiba did teach it, others will say that he did not. Some will say "Fault of student." Others will say "Fault of teacher."
I'm past caring anymore.
We have a strange situation in the martial arts.
1. Those who don't really have IP/aiki are convinced their teachers are teaching them the real goods, and that their teachers are amazing
2. Those who either have it or have at least started to feel it, now "see." What they see, is that the real heart of the arts is all but lost. Few "have it" to any serious degree, and of those that do, the majority seem to either not know how, or are uninterested, in teaching it.
As for Ukemi, principles of aikido techniques and so on:
What comes first? Not my job to guess what he did and why or decide for you or anyone else.
I say that while it is good to learn Ukemi, and fighting principles....it is best to learn IP/aiki, which for the most part negates techniques and the need for ukemi.
But I've stopped trying to convince people with words.
IP/aiki is the single most important thing in the arts. It goes from basic to refined movement. Everything else is a shadow.
