Bit by Bit - Chapter 6, Part 1

Trey Smith

He who knows what it is that Heaven does, and knows what it is that man does, has reached the peak. 

Knowing what it is that Heaven does, he lives with Heaven. Knowing what it is that man does, he uses the knowledge of what he knows to help out the knowledge of what he doesn't know, and lives out the years that Heaven gave him without being cut off midway - this is the perfection of knowledge.
~ Burton Watson translation ~

Sounds to me very similar to Reinhold Niebuhr's Serenity Prayer.

God, grant me the serenity to accept the things I cannot change,
The courage to change the things I can,
And the wisdom to know the difference.
