"Much of your pain is self-chosen.
It is the bitter potion by which the physician within you heals your sick self.
Therefore trust the physician, and drink his remedy in silence and tranquility:
For his hand, though heavy and hard, is guided by the tender hand of the Unseen,
And the cup he brings, though it burn your lips, has been fashioned of the clay which the Potter has moistened with His own sacred tears."
