"Whence comes the powerful impression that is made upon us by the tomb? Are a few grains of dust deserving of our veneration? Certainly not; we respect the ashes of our ancestors for this reason only — because a secret voice whispers to us that all is not extinguished in them. It is this that confers a sacred character on the funeral ceremony among all the nations of the globe; all are alike persuaded that the sleep, even of the tomb, is not everlasting, and that death is but a glorious transfiguration."
