《资治通鉴·唐纪·唐纪十九》
百姓安定就对活着感到愉快，不安定就对死看得很轻，对死看得很轻就什么事都做得出来，邪恶叛逆之徒乘机而起，天下也就乱了！ 
百姓安则乐其生，不安则轻其死，轻其死则无所不至，祆逆乘衅，天下乱矣！ 
If the people are settled they are happy to be alive, if they are unsettled they do not set much store by death, if they do not set much store by death they will do anything, and wicked rebels will take this opportunity to rise up and the country will fall into chaos!
