Know and understand that there is no similarity in substance or structure between God and us - except for the intention of the forms of our organs and limbs, which are fashioned as symbols of hidden, supernal realities. The mind cannot know these realities directly; it can only be reminded of them. As when one writes "Reuben son of Jacob." The form of these letters is not the form, structure, and essence of the real Reuben son of Jacob but simply a mnemonic device. "Reuben son of Jacob" is a symbol of the particular entity called by that name.

Since God wanted to purify us, he created in the human body various organs and limbs - hidden and revealed - as symbols of the divine structure. If one succeeds in purifying a particular organ or limb, it becomes a throne for the sublime, inner reality called by that name: "eye," "hand," or any other one.

God most high has said: 'When I love a servant, I, the Lord, am his ear, so that he hears by me; I am his eye, so that he sees by me; I am his tongue, so that he speaks by me; and I am his hand, so that he takes by me.'
