Existence is of two kinds: one is the existence of God which is beyond the comprehension of man. He, the invisible, the lofty and the incomprehensible, is preceded by no cause but rather is the Originator of the cause of causes. He, the Ancient, hath had no beginning and is the all-independent. The second kind of existence is the human existence. It is a common existence, comprehensible to the human mind, is not ancient, is dependent and hath a cause to it. The mortal substance does not become eternal and vice versa; the human kind does not become a Creator and vice versa. The transformation of the innate substance is impossible.
