A woman was taking a Japanese Shihan's seminar somewhere in the USA. She heard him say, "Aikido should be done with arrogance!". It was a bit shocking to her, but, as it was his seminar, she decided to give it a try. It worked wonderfully. Her techniques started to flow. She felt really in charge and everything went great. After the class, she went to her Sensei and told him about her breakthrough. He looked at her and said, "He said that Aikido should be done with elegance.".
IMHO, true elegance can be very intimidating. There is an internal intent and intensity that make makes it all look easy. What looks like arrogance to one (fear based) may appear as elegance to another (love based). Its all in the eye of the beholder.
