Allah Almighty, in order to display His infinite power and unlimited mercy, has made inherent in man infinite impotence and unlimited want. Further, in order to display the endless embroideries of His names, He has created man like a machine capable of receiving unlimited varieties of pain, as well as infinite varieties of pleasure. Within that human machine are hundreds of instruments, each of which has different pains and pleasures, different duties and rewards. Simply, all of the divine names manifested in the macroanthropos that is the world also have manifestations in the microcosm that is man. Beneficial matters like good health, well-being, and pleasures cause man to offer thanks and prompt the human machine to perform its functions in many respects, and thus man becomes like a factory producing thanks.
Similarly, by means of misfortune, illness and pain, and other motion-inducing contingencies, the other cogs of the human machine are set in motion and revolution. The mine of weakness, impotence, and poverty inherent in human nature is made to work. It induces in man a state whereby he seeks refuge and help not only with a single tongue, but with the tongue of each of his members. Thus by means of those contingencies man becomes like a moving pen comprising thousands of different pens. He inscribes the appointed course of his existence on the page of his life or the Tablet in the World of Similitudes; he puts forth a declaration of the divine names; and becomes himself an ode to the glory of Allah, thus fulfilling the duties of his nature.
