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.
Nothing Can Exist Without the Ein Sof's Involvement
