each and every attribute exists through itself. The modes have reasons for existing; I am here for a large number of reasons, not the least a which being the fact that i was born. But the attributes have absolutely no reason as to why they exist, they just do. God is the indwelling cause of all things. While modes are determined in their existence by other modes, it is through God that they exist at all. God is utterly and completely incomprehensible to humans (a human being one of his ideas). He is infinite in so far as he is constituted by infinite attributes. This is a strange idea, and literally impossible to conceptualize adequately. He does have a certain nature, There is an idea for every mode of extension and corresponding to each of these things is an infinite amount of attributes. Everything follows the same form ,the physical laws of our extended universe and universe of thought= nature of God. We only see two layers of it.
