Six in the third place means

One is enriched through unfortunate events.

No blame, if you are sincere

And walk in the middle,

And report with a seal to the prince.

A time of blessing and enrichment has such powerful effects that even events ordinarily unfortunate must turn out to the advantage of those affected by them. These persons become free of error, and by acting in harmony with truth they gain such inner authority that they exert influence as if sanctioned by letter and seal.
