"Tai Chi Chuan (Taijiquan) practitioners harbor the dream of developing the magic of Neijin (Internal Strength). Neijin—the stuff of the kungfu prowess of Taijiquan—is mysterious because the art of Taijiquan resides in the internal, not characterized by the vigor of physical activities that we are familiar with. Neijin seems to defy physics, but there is no new physics."
