"Once centenarian teacher who had the body of an adolescent told me he had studied martial arts. "Me, too," I answered. We were in Notre Dame, and he said, "Attack me." I put myself in a combat position, and he moved his left hand in such an incredibly beautiful way that while I looked at it, fascinated, he gave me a big slap. "Beauty is the most dangerous weapon," he warned. It took me a long time to understand. He used a secret Chinese practice, which consists of drawing a snake in the air with your hand to distract the enemy. And that is how beauty is: the most awful weapon."
