Therefore, even if the lords, whom you serve at the risk of your life, force you to abandon your faith or severe persecution befalls you, do not retreat. Instead muster your faith in the Lotus Sūtra, and regard it as a good opportunity to see whether or not deities keep the promise they made to the Buddha. Your steadfast faith will enable the soul of your father to become a Buddha and he will come to protect you. Then all the obstacles and challenges will disappear, and you will be able to enjoy living in ease and comfort. When you encounter oppression, therefore, gladly accept it as the moment of truth.
