Six in the third place means:

Whoever hunts deer without the forester
Only loses his way in the forest.
The superior man understands the signs of the time
And prefers to desist.
To go on brings humiliation.

If a man tries to hunt in a strange forest and has no guide, he loses his way. When he finds himself in difficulties he must not try to steal out of them unthinkingly and without guidance. Fate cannot be duped; premature effort, without the necessary guidance, ends in failure and disgrace. Therefore the superior man, discerning the seeds of coming events, prefers to renounce a wish rather than to provoke failure and humiliation by trying to force its fulfillment.
