In plain words
If manifest clarity is postulated for objects, agents, and the rest, then clarity and obscurity belong only to what is other than the Self, never to the inner Self.
Close to the Sanskrit
If the established manifestness of the object, agent, and others is postulated, manifestness and unmanifestness would belong to another alone, and not to the Self.
