Re: The Fear of Power
As Chris indicated, I believe autonomy (or rather, autonomous) is a form of power. In particular, it is a form of power expressed with a freedom from control; a power independent of external influence. So in answer to your question, no, I am not confusing power with autonomy. More precisely, I would say autonomy is just a type of power.
As it would happen, I believe this power to be the core of my aikido - the power to act under my own authority without external influence affecting my actions. Right now, I think the lingo is "independent movement".
