In other hexagrams, a nine dwelling in the second place means occupying a yielding position and attaining the Central Position, carrying no connotation of excessive firmness.
But in Before Completion, the sage drew deeply upon the hexagram image to set forth a warning, making clear the way of respectful compliance in serving one's superior.
Before Completion is a time when the ruler's path is fraught with hardship: Six in the Fifth Place occupies the ruler's throne with yielding, while Nine in the Second Place possesses firm yang talent and occupies the position of corresponding partnership—the very one who must be employed.
Firmness carries the implication of encroaching upon the yielding, and water bears the image of overcoming fire. In a time of hardship, what is relied upon is simply a talented minister; thus he must especially fulfill the way of respectful compliance.
Therefore the warning is given: dragging its wheels brings correctness and good fortune. Dragging the wheels backward slows and checks its advance, warning against the excessive use of firmness. When firmness is excessive, one is prone to offend superiors and lacks compliance.
Guo Ziyi and Li Sheng of the Tang dynasty, facing grave peril before completion was achieved, were able to exercise the utmost respectful compliance; this was how they attained correctness and preserved ultimate good fortune.
For Six in the Fifth Place, the text speaks of steadfast good fortune and glorious brilliance, fulfilling the excellence of the ruler's way; for Nine in the Second Place, it warns to be respectfully compliant, fulfilling the correctness of the minister's way—fulfilling the ways of both superior and subordinate.
