Nine in the second place means:
Here advance is checked just as in the third line of hexagram 9 the Taming Power of the Small. However, in the later the restraining force is slight; thus a conflict arises between the propulsive and the restraining movement, as a result of which the spokes fall out of the wagon wheels, while here the restraining force is absolutely superior; hence no struggle takes place. One submits and removes the axletrees from the wagon -in other words, contents himself with waiting. In this way energy accumulates for a vigorous advance later on.
