Having begun to think in this way he begins to find that if there is any substance, it is something that He made out of Himself. One can see that by considering one's own thoughts. When a person notices that a thought has come to him to do a certain thing, where was it before? How did it arise? Surely, his mind has in that case created something out of nothing, or out of himself. Mind is one thing, thought is one thing, but at the same time the thought is of the mind, the mind has created the thought, and yet the thought is not another substance, it is the substance of mind itself.
