As an example, think about the difference between physics and mathematics. The laws of physics are contingent and are part of Creation, whereas mathematical truths are necessary and uncreated. As necessary truths, mathematics belong to Heaven, in the mind of God, whereas physical laws, as contingent truths, belong to the heavens. The laws of physics are patterns that do govern the lower levels of Creation, but they are part of Creation. Mathematical truths exist at a higher, eternal level of Being and govern all of Creation.
