Six in the third place means

Hidden lines.

One is able to remain persevering.

If by chance you are in the service of a king,

Seek not works, but bring to completion.

If a man is free of vanity he is able to conceal his abilities and keep them from attracting attention too soon; thus he can mature undisturbed. If conditions demand it, he can also enter public life, but that too he does with restraint. The wise man gladly leaves fame to others. He does not seek to have credited to himself things that stand accomplished, but hopes to release active forces; that is, he completes his works in such a manner that they may bear fruit for the future.
