From 'Nine in the Third Line says' to 'with whom one can preserve righteousness.' Sub-commentary: This explains the line statement of Nine in the Third Line.
'The Master said: The gentleman advances virtue and cultivates his vocation': virtue refers to virtuous conduct; vocation refers to meritorious deeds.
Nine in the Third Line remains active and vigilant all day because he seeks to increase his virtue and cultivate his vocation untiringly.
Advancing virtue means 'knowing the ultimate' and preparing to advance; cultivating vocation means 'knowing the end' and preserving righteousness.
'Loyalty and good faith are the means to advance virtue': extending loyalty to others and treating all with good faith causes people to respect and draw close to him, advancing his virtue daily.
'Cultivating words and establishing sincerity are the means to dwell in one's vocation': words refer to cultural teachings; sincerity refers to inner truth.
Cultivating cultural teaching externally while establishing sincerity internally unites inner and outer, creating achievements in which one can dwell.
'Knowing the ultimate and attaining it, with whom one can examine the seeds of things': Nine in the Third Line occupies the extremity of one trigram, about to reach beneath the upper trigram; this is 'the ultimate.'
Dwelling beneath the upper trigram without fault is 'knowing the ultimate.' Knowing that the time is arriving means discerning the subtle seeds of principle, enabling one to examine imperceptible beginnings.
'The seed' is the moment when principle has emerged from non-being into being but has not yet taken physical shape. 'Knowing the end and concluding it, with whom one can preserve righteousness': dwelling at the end of a trigram and preserving it completely is 'knowing the end.'
Recognizing this conclusion allows one to preserve righteousness. Righteousness means appropriateness: safeguarding one's position without loss keeps affairs appropriate.
Nine in the Third Line, being a single line, may either advance by knowing the seeds or retreat by preserving righteousness, enacting both according to the proper time.
On the note from 'dwelling at the culmination of a trigram represents the ultimate' to 'is it not solely he who knows the end?': Sub-commentary: Master Zhuang says: 'The extremity is the ultimate. The third line atop the lower trigram is the ultimate.'
Master Chu says: 'The extremity of a trigram is the ultimate because the lower trigram has reached its end and is about to reach beneath the upper trigram.'
Below it says 'in a lowly position without anxiety,' and the note explains 'knowing how to reach the ultimate, he is not anxious.' Since it says 'lowly position,' he knows he is beneath the upper trigram and wishes to advance to it; hence he is not anxious.
'Dwelling at the culmination of affairs without incurring blame belongs to knowing the ultimate': being close to the upper trigram, he knows how to yield with propriety and avoid blame.
'Hence one can accomplish tasks with him': recognizing subtle beginnings allows one to accomplish undertakings. 'In advancing things swiftly, righteousness is not as swift as profit': profit acts upon opportunity; seeing gain, it moves.
Righteousness moves according to proper measure and does not rashly seek advancement. 'In preserving things to the end, profit cannot match righteousness': preserving what is already completed requires avoiding rash action; hence profit falls short of righteousness.
'Thus all things have a beginning, but few can bring it to completion': acting purely for profit neglects what follows, showing that many begin but few complete their vocation.
'Therefore, he occupies a superior position without pride, and dwells in a lowly position without anxiety.' Sub-commentary: Dwelling atop the lower trigram without pride is because he 'knows the end.'
Dwelling beneath the upper trigram without anxiety is because he recognizes approaching affairs and prepares to advance.
On the note 'clearly understanding ultimate decline, he is not proud' to 'he is not anxious': Sub-commentary: 'Understanding ultimate decline' explains 'knowing the end.' 'Knowing how to reach the ultimate' explains 'knowing the ultimate.'
'Hence he is active and vigilant' to 'there is no blame.' Sub-commentary: For these reasons, Nine in the Third Line remains active and vigilant. Apprehensive in mind, his knowledge of the end and the ultimate keeps him free from blame.
On the note 'dwelling at the extremity of affairs' to 'laxity leads to neglect': Sub-commentary: If he misses the time and fails to advance, vital affairs are neglected; hence he must advance with vigilance.
If he grows proud and lax, his accomplishments are ruined; hence he must preserve what he has achieved. 'Missing the proper time leads to ruin' explains 'knowing the ultimate'; 'laxity leads to neglect' explains 'knowing the end.'
