《管子·形势解》
行事合于天道，出自公理，则远者都来亲近；废天道，按私心行事，则母子互相怨恨。
行天道，出公理，则远者自亲；废天道，行私为，则子母相怨。
 If one's actions conform to the way of heaven and come from justice, then even those far away will come close; if one abandons the way of heaven and acts out of selfishness, then even mother and son will resent each other.
