From "Nine in the Second Place" to "the secluded hermit's perseverance brings good fortune." The Zhengyi commentary says: "The way of conduct is level and smooth": "level and smooth" depicts an easy, unhindered path.
Nine in the Second Place, being yang, dwells in a yin place, treading upon modesty and retreat; being able to maintain modesty, "the way of conduct is level and smooth," easy and free from dangerous perils.
"The secluded hermit's perseverance brings good fortune": since there are no dangerous perils, a person living in hidden seclusion who maintains correctness attains good fortune.
Regarding Wang Bi's note, "The way of conduct values modesty" to "it is rightly auspicious": The Zhengyi commentary says: "The way of conduct values modesty" means the path of conduct esteems modest retreat; only then can one interact with all things.
"Treading" also means propriety, hence "values modesty." "Dwelling within, it treads the center; hidden or manifest, it remains the same": the way of conduct values modesty and dislikes dwelling in fullness; occupying yin with yang, it esteems modest virtue.
"Dwelling within, it treads the center," taking trust as its way, not considering external prominence as glory or internal seclusion as humiliation.
Even if dwelling outside, it would still tread the center in modest retreat; whether in hiding or in prominence, the mind remains equal, hence "hidden or manifest, it remains the same."
"Persevering in seclusion, it is rightly auspicious": because it is in the center of the inner trigram, it is said to be "in seclusion." Modest and holding the center, this is upright perseverance.
Being able to practice this correctness in seclusion, it is said that "it is rightly auspicious."
