19.君子敬以直內，義以方外。——出自《坤·文言》
今譯:每位有德行的人對自己要求做到端直莊敬，對外做事要方正而符合義。
衍言:人無私心，其內自直；行事守義，其外自方。內直外方，其德自然高尚。
《周易》小詞典：直內：謂正直發於心。方外：“方”謂不詭隨、不苟同。以方正之義待人接物，稱方外。
The superior man, by his self-reverence maintains the inward correctness, and in righteousness adjusts his external acts.——- from The Record of Wen Yan, Kun
Modern interpretation: A virtuous man is supposed to be upright and dignified about himself. Outwardly he should do everything straightforward according to principle.
Moral: An unselfish man is self-reverened inside. His righteous deeds make himself square outside. With the inward straightness and outward squareness, his moral character is naturally lofty.
Glossary: Inward straightness means that a man is honest and straightforward from the bottom of his heart. And outward squareness requires the man to be independent and ready to differ, who is always righteous and upright in dealing with people.
