This is an empty room, there is nothing in it.

这是一间空屋子，里面没人住。

When we go into an empty room or stay alone in one, we should act the same as when there are people around; we shouldn't be the least bit casual or lax; this is the essence of self-cultivation.

至于进入空屋或独处虚室之时，还能如同有他人在侧，没有一丝一毫的随便和放逸，这更是自我淬炼之所在。
