With all due respect since I did not ask Tamura Sensei what training he did or didnt do to acquire this skill one cannot presume that the basic training you indicate is necessarily the same method as Tamura Sensei used.It may well be the same but then again it may not.Oh well -shrug??
Well to yield the results you are talking about...the same as is seen culture to culture....it should start to ring some bells that it is the same basics. The same ones the Indian and Chinese wrote about, and Ueshiba quoted!
Then we have to ask.....
Why can't everyone do it? It's a basic?
Or was it on purpose?
Thankfully there are those willing to do the job others can't or won't.
