"The righteous person, the Tzaddik, transforms the evil to good within himself, as well as within the context of the world.
The Tzaddik does not feel suffering in the same way as other men.
He does not recognize it as something special to be feared and avoided.
It is, for him, like all else in life, a fact of existence.
One eats, one sleeps, one acts, one suffers.
Everything is translated into good."
From Pebbles of Wisdom from Rabbi Adin Steinsaltz (forthcoming)
