Aikido is supposed to be non-oppositional, this is an example of a technique where we often miss that point. Kosa dori is a very powerful grab, creating a dangerous opportunity for an attack. Saito sensei highlights how freely moving what is available creates an opportunity for release and safety. Good for aikido, good for understanding how power does not create resolution.
