Nine in the third place means

A good horse that follows others.

Awareness of danger,

With perseverance, furthers.

Practice chariot driving and armed defense daily.

It furthers one to have somewhere to go.

The way opens; the hindrance has been cleared away. A man is in contact with a strong will acting in the same direction as his own, and goes forward like one good horse following another. But danger still threatens, and he must remain aware of it, or he will be robbed of his firmness. Thus he must acquire skill on the one hand in what will take him forward, and on the other in what will protect him against unforeseen attacks. It is good in such a pass to have a goal toward which to strive.
