Know, may God help you, that since what was meant by this world was the human being, who is the Imam, therefore we added fathers and mothers to it, so we said, “Our upper fathers and our lower mothers.” Every influence is a father, and every influence in it is a mother. This is the rule for this chapter, and what is generated between them from that effect is called a son and a generator, and so are the meanings in production. Science is based on two premises, one of which marries the other, with the single singular that is repeated in them, which is the link, which is marriage, and the result that emerges between them is what is required. All souls are fathers, and nature is a mother since it was the place of transformations. These souls are guided by these pillars, which are the elements that are subject to change, and transformations appear in them, which are minerals, plants, and animals. The jinn and humans are the most complete.
