Unity of spirit and action
The unity of agility and agility refers to the high degree of unity of body and mind, which is what we usually call the speed of reflection. The unity of spirit and action is achieved through practice, not the illusory practice of martial arts in novels, but through constant penance to stimulate your nerves and make your sensory nerves more acute. If we reach a certain level, we can achieve the unity of agility and agility, and avoid beauty and alcohol at the right time.
