《后汉书·列传·杨李翟应霍爰徐列传》
刑罚威狱，用来像天之震耀杀戮；温慈和惠，仿照天之生殖长育。因此春天一草枯就是灾，秋天一木开花就是异。
夫刑罚威狱，以类天之震燿杀戮也；温慈和惠，以放天之生殖长育也。是故春一草枯则为灾，秋一木华亦为异。
Punishment and imprisonment are used to imitate the sky's shocking killing; warmth and kindness are imitated from the sky's reproduction and growth. Therefore, if one grass withers in spring, it is a disaster, and if one tree blossoms in autumn, it is strange.
