Meditation upon death does not teach one how to die; it does not make the departure more easy, but ease is not what I seek. Beloved boy, so willful and brooding, your sacrifice will have enriched not my life but my death.... Centuries as yet unborn within the dark womb of time would pass by thousands over that tomb without restoring life to him, but likewise without adding to his death, and without changing the fact that he had been.
