Kahlil Gibran, The Prophet: On Pain and On Death

And a woman spoke, saying, "Tell us of Pain." And he said: 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. And could you keep your heart in wonder at the daily miracles of your life, your pain would not seem less wondrous than your joy; And you would accept the seasons of your heart, even as you have always accepted the seasons that pass over your fields. And you would watch with serenity through the winters of your grief. 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. 
Then Almitra spoke, saying, "We would ask now of Death." And he said: You would know the secret of death. But how shall you find it unless you seek it in the heart of life? The owl whose night-bound eyes are blind unto the day cannot unveil the mystery of light. If you would indeed behold the spirit of death, open your heart wide unto the body of life. For life and death are one, even as the river and the sea are one. In the depth of your hopes and desires lies your silent knowledge of the beyond; And like seeds dreaming beneath the snow your heart dreams of spring. Trust the dreams, for in them is hidden the gate to eternity. Your fear of death is but the trembling of the shepherd when he stands before the king whose hand is to be laid upon him in honour. Is the sheered not joyful beneath his trembling, that he shall wear the mark of the king? Yet is he not more mindful of his trembling? For what is it to die but to stand naked in the wind and to melt into the sun? And what is to cease breathing, but to free the breath from its restless tides, that it may rise and expand and seek God unencumbered? Only when you drink from the river of silence shall you indeed sing. And when you have reached the mountain top, then you shall begin to climb. And when the earth shall claim your limbs, then shall you truly dance.
