《三国志·蜀书·先主传》
曾听说圣明的君王在天时之前行事，天命也不会违背他的意思，再天时之后行事则是顺应天意，所以能顺应天命，跟神灵契合。
臣闻圣王先天而天不违，后天而奉天时，故应际而生，与神合契。
It has been said that the wise kings act before the right time, the will of heaven will not go against his will, act after the right time is to follow the will of heaven, so to follow the will of heaven, coincides with the gods.
