The word must be heard in silence; there must be darkness to see the stars.
To learn which questions are unanswerable, and not to answer them: this skill is most needful in times of stress and darkness.

Darkness is only in the mortal eye, that thinks it sees, but sees not.
The sunlights differ, but there is only one darkness.
No darkness lasts forever. And even there, there are stars.
