《新唐书·列传·卷三十二》
危机不被引发就是福，一旦爆发就是祸，百姓安宁就贪生爱命，动荡不安就轻生拼命正是这个道理。
机静则有福，动则有祸，百姓安则乐生，不安则轻生者是也。
If a crisis does not occur, it is good fortune. Once it breaks out, it brings calamity. That peaceful people covet life and timidly flee death, but that unsettled people readily die and impetuously fight for life and death, is the very principle behind this.
