33.履道坦坦，幽人貞吉。——出自《履·九二爻》
今譯：人能秉行謙而好禮之道，那麼前途就會平順而無險阻；能幽靜安恬，就會貞固守正而得吉。
衍言：人忌行為怪誕而驚世駭俗，更忌張揚炫耀而惹事生非。
《周易》小詞典：九二爻以剛居中，稱為道；以剛居柔，稱為坦；與九五爻無應，有幽人守貞之象。
Treading the path that is level and easy, a quiet and solitary man will enjoy good fortune, if he is firm and correct.——- from The Second Line, Undivided, Lu
Modern interpretation: If people are all self-effacing and courteous, there would be a smooth development without twists and turns. Everyone would feel ease and comfortable, and keep firm and correct to enjoy good fortune.
Moral: People should avoid odd behaviors which scandalize the public. More importantly, they should not abandon themselves to show-off for troubles.
Glossary: The second line, a strong line undivided, of this hexagram occupies the middle place of the trigram, which is supposed to symbolize a path. Strength in docility is like treading a path cut straight and level. No response to the fifth line creates the image of a quiet and solitary man who sticks to his virtue.
