I don't exactly know what this Zen saying means.

That's the way of the Buddhist koan.  They are short statements or questions that are often a paradox. They are ambiguous. There is no one meaning; no one understanding. They are tools for the purpose of fostering contemplation. 

My point in using it was to supplement the message of this week's editorial, "A changed landscape?"

No matter the national landscape, each of us has the opportunity and the responsibility to apply ourselves to our chores at hand. And, in this particular case, that is to remain focused on the solid community work and achievements that can be accomplished when we work together. Especially, as we don't any of us know what's on the horizon.
