I've said this before but I will say it again (hopefully more briefly this time):
It seems to me that AiKiDo is about learning to change your perspective. For me it works when I manage to take a situation that I would have normally thought of as martial or full of conflict and redefine it for myself as one in which tools of cooperation and understanding would be more effective.
It is a martial art in the sense that it starts with a situation in which I perceive conflict. It transcends martial arts in that it teaches me to see them afresh.
