言有教，动有法；

昼有为，宵有得；

息有养，瞬有存。

——张载《正蒙·有德》

言语有礼教，行动有法则；

白天有作为，夜间有收获；休息有所养，瞬间有所存。

“Whatever one says, it must be educational. Whatever one does, one must follow rules. During the day, one should exert himself, and at night, one should reflect on himself. One should nourish his body when in repose. Not for even a brief moment should one indulge himself.”

“Being Virtuous” from The Zhengmeng (Correcting Ignorance)
