Re: teachers who don't speak
My first teacher was Juba ( Nour, 5th ? Dan under TK Chiba Shihan), and he said very little. The only things he said on the mat were "you're too stiff", and "no talking". My second, TS Okuyama Sensei just paced the mat with a Cheshire -cat smile.The lesson was this: when the teacher starts talking, the student stops moving. Period. And it can degrade to a condition where precious time that might be spent moving is wasted standing.
