Another famous martial arts adage notes, "The ears listening aren't as good as the mind listening, which isn't as good as the qi listening," If you put this into practice on the battlefield, you will, via heightened sensitivity, be able "to know your enemy's movements in advance.
所謂「耳聽不如心聽，心聽不如『氣』聽」，臨陣交手時，對手一有動靜也會立刻感知，自然可以「料敵機先」了。
