天行健，君子以自强不息;地势坤，君子以厚德载物
“天行健”出自《周易》：“天行健，君子以自强不息”（乾卦）、“地势坤，君子以厚德载物”（坤卦）。意谓：天（即自然）的运动刚强劲健，相应于此，君子应刚毅坚卓，发愤图强；大地的气势厚实和顺，君子应增厚美德，容载万物。译为：君子应该像天宇一样运行不息，即使颠沛流离，也不屈不挠；如果你是君子，接物度量要像大地一样，没有任何东西不能承载。
在周易的英译本里 这两句是这样译的
The movement of heaven is full of power.
Thus the superior man makes himself strong and untiring.
The earth's condition is receptive devotion.
Thus the superior man who has breadth of character carries the outer world.
北京外国语大学李长全教授 主编的一本书中的 译文
As heaven maintains vigor through movements,
a gentle man should constantly strive for self-perfection.
As earth's condition is receptive devotion,
a gentle man should hold the outer world with broad mind.
