Nine at the beginning means:

Waiting in the meadow.
It furthers one to abide in what endures.
No blame.


The danger is not yet close. One is still waiting on the open plain. Conditions are still simple, yet there is a feeling of something impending. One must continue to lead a regular life as long as possible. Only in this way does one guard against a premature waste of strength, keep free of blame and error that would become a source of weakness later on.
