The spirit comes into play when you don't see uke as the enemy but as another self. When you don't see that those that disagree with you as seperate or wrong. When you don't think that you are more or less human than others. Aikido shows us all that.
Very well formulated. It is a view that is shared by Buddhism and Shinto / Taoisme. And very much part of Aikido. If we come on the tatami with the notion that we are in any way more then the others then Aikido will be a humbling experience.
