疾病是对身体的障碍，而不是意志，除非意志本身选择。 la脚是对腿的障碍，但对意志的障碍不是。并在发生的一切时添加这种反思；因为您会发现这是对其他事物的障碍，但对自己却不是。
(Disease is an impediment to the body, but not to the will, unless the will itself chooses. Lameness is an impediment to the leg, but not to the will. And add this reflection on the occasion of everything that happens; for you will find it an impediment to something else, but not to yourself.)
