The second line is restrained and stopped by Six in the Fifth Place; the situation does not allow advance. The fifth line occupies the superior position above; how could it be defied?
Although the second line is of a firm and strong trigram, its position attains the Central Way, so in advancing and stopping it makes no error.
Though it aspires to advance, assessing that the circumstances do not allow it, it halts and does not move, like a wagon having its axle-straps removed, meaning it does not travel. The Xiang says: 'The straps are removed from the wagon; in the center there is no blame.'
The straps being removed from the wagon so that it does not travel is because its dwelling attains the Central Way; its movements never lose propriety, hence there is no fault or blame. Nothing is better than being firm and central.
Yielding centrality merely avoids excessive yielding; firm centrality possesses both the center and talent. Nine at the Beginning does not dwell in the center, hence it is warned that there is danger and it ought to cease.
Line two attains the center, so in advancing and stopping it is naturally free of errors; therefore it only says the straps are removed from the wagon, indicating its ability not to move. Not moving, it is free of blame.
The initial and second lines, being of the Qian trigram, are firm and strong yet unable to advance; the fourth and fifth lines are yin and yielding yet able to restrain them.
The ebb and flow of the times, the strength and weakness of positions—these are what students of the Changes should profoundly understand.
