Please understand that I mean no ill will, but it's contrary to what I want or why I train. My sensei has a sensei, and his sensei was the founder of our style. We have an actual lineage, and each sensei was given permission to teach by their own instructor. I see that as incredibly important.
I agree, Bill, but not everyone is as fortunate. Some of my instructors have passed away, others have moved far away and we rarely get to train together anymore.
But we (me and mine) weren't just given permission to teach by our instructors, we were threatened (in a good way) if we didn't keep teaching.
