I may venture to say, loosely, that in Judo there is a sort of counter for every twist, wrench, pull, push or bend. Only the Judo expert does not oppose such movements at all. No, he yields to them. But he does much more than yield to them. He aids them with a wicked sleight that causes the assailant to put out his own shoulder, to fracture his own arm, or in a desparate case, even to break his own neck or back.
