Part 2: Even so, all that is rooted there could not have come into being without the Unlimited Himself governing it. For there are entities whose movements are self-generated, and others whose movements depend upon another. For example, the movements of the body depend upon another, while the movements of the soul are self-generated. All this must have a root above. If so, among the lights there must be some whose movements are self-generated, and they are the root of those entities having this property, while different lights, whose movements depend upon other lights, are the root of those entities that have that property.
