Six in the third place means:

To nourish oneself on ancient virtue induces perseverance.
Danger. In the end, good fortune comes.
If by chance you are in the service of a king,
Seek not works.

This is a warning of the danger that goes with an expansive disposition. Only that which has been honestly acquired through merit remains a permanent possession. It can happen that such a possession may be contested, but since it is really one's own, one cannot be robbed of it. Whatever a man possesses through the strength of his own nature cannot be lost. If one enters the service of a superior, one can avoid conflict only by not seeking works for the sake of prestige. It is enough if the work is done: let the honor go to the other.
