Even in our sleep, pain which cannot forget
falls drop by drop upon the heart,
until, in our own despair,
against our will,
comes wisdom
through the awful grace of God.

as quoted by Robert F Kennedy

 

Wisdom comes through suffering.
Trouble, with its memories of pain,
Drips in our hearts as we try to sleep,
So men against their will
Learn to practice moderation.
Favours come to us from gods.

original as written by Aeschylus ( from Trilogy, Oresteia)
