Thou shalt understand that it is a science most profitable, and passing all other sciences, for to learn to die. For a man to know that he shall die, that is common to all men; as much as there is no man that may ever live or he hath hope or trust thereof; but thou shalt find full few that hath this cunning to learn to die. I shall give thee the mystery of this doctrine; the which shall profit thee greatly to the beginning of ghostly health, and to a stable fundamental of all virtues.
