““People who do not examine themselves are like people with a sickness that closes off their capillaries and therefore corrupts their blood, causing their limbs to go to sleep and atrophy, and resulting in severe chronic diseases because their humors, and therefore the blood that arises from them, are viscous, sticky, irritating, and acidic. People who do examine themselves, however, including the intentions of their will, are like people who are healed from these diseases and regain the vitality they felt when they were young. People who examine themselves in the right way are like ships from Ophir completely filled with gold, silver, and precious stones; before they examined themselves, though, they were like barges loaded down with unclean freight, carting away the filth and excrement from city streets. . . .””
