Quote from : The Prophet Book

Your pain is the breaking of the shell that encloses your understanding. Even as the stone of the fruit must break, that its heart may stand in the sun, so must you know pain. 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 tranquillity: 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.
