Actually I think it is only the transmission of knowledge that provides the quality of aikidō. I think practicing budō is about transmission of what is already there, transmission of what was known by those before us. It is not about searching and exploring. It is about finding and revealing.
I absolutely disagree, Carsten. I want to go further. To do anything less would be a disservice to those who went before us. I did receive knowledge from my teachers, and I keep unpacking it. It's the gift that keeps on giving. I also receive new knowledge and new experiences that they never had. And I live in completely different times and surroundings and culture than they did.
My main aikido teacher said, "Budo must always reflect its surroundings. If it isn't newer and stronger, it isn't valid."
I'm not interested in the Budo of the last 25 years. I've already lived through it. Been there. Done that. I'm more interested in the Budo that will be evolving in the next 25 years.
