four activities of daily life ［四威儀］ ( shi-igi): Also, four daily activities or four modes of conduct. Walking, standing, sitting, and lying down. The activity of standing means the state of standing still and also the motion of standing up. The same applies to the other three. The term “four activities of daily life” is often used to refer to all modes of human behavior. In Buddhism, the various rules of conduct were prescribed with regard to the four activities of daily life, and it was required that monks and nuns be correct in all their modes of behavior, and that their four daily activities accord with the rules of conduct.
