Re: Seiza by ranks?
Maybe I'm tired and have had a bad day....
But I really don't see the purpose of lining up in any particular order.
Let me correct that - I do see a couple of reasons, but I don't want those reasons in my dojo.
I did grow up in aikido with sitting in ranks, but it was a Ki Soc (coloured belts) dojo so at least it was done more quickly and neatly. No seniority within the same grade.
For me, the priority is to get people sitting quietly with as little fuss and as much decorum as possible. Having a seating order just seems to get in the way of that, and raise up enough problems of its own.
