Chris, accountable to whom? and why? This concept is beyond me. In the old days all koryu were closed and private. It was very difficult to be admitted as a student even with a letter of introduction from a highly respected person. It was the headmaster's way or you were not a member. The ryu was accountable to no one. This is still a good way for modern budo. For me the idea of being accountable to a second or third party is outside of my understanding.
To hold thoughts of being accountable can really be a negative thing on your training. The over used statement "just do it" fits here.
I had a long layoff due to a serious knee injury. When I first came back I had a fear of ukemi. It really held me back. I kept thinking I would injure my knee again. When I decided to stop thinking and just do it I was shocked at how easy it came back to me. The thinking was holding me back. If I had to think about accountabality I would just give up.But thats just me. I have been lucky to have received great instruction and thus never had any doubt about the art or teacher.
Chris, do have have these thoughts because you are in doubt about the instruction that you are getting?
I am not a scholar, but I believe in the old days, ryus were held accountable. Accountable to the results they produced in a society that trained these guys for practical purposes. In modern times it becomes an esocteric practice with a lot of people running around in costumes, re enacting an anachronism that has little to do with the real world. There are very few that are qualified to interpret these tactics and methodologies of days gone by.
So I think that probably has a lot to do with Chris' point.
