"What is the point of training in a martial art that has you entering into practice with the intention of falling down?"
It's not an exact quote, but it's close enough, revealing the questioner's mind clearly: Dominance and victory in physical conflict is paramount. That's what he's come to learn. He has no idea that it's his subservience to this need that brought him here in the first place.
I'm sure his spouse nods accomodatingly at the dinner table as he brags about his exploits. "Yes, Dear... Now can you show me how you use that skill to effortlessly lift that trash bag? Amazing!"
Someone who must dominate is easily led by one who will "submit." Therefore, proper aikido practice exercises discipline over the yang as well as the yin within each of us.
