Gnostic models are mental models. This is meant in two ways: they are models of our mind and they are models that our mind uses.
If we do not have a model of the mind that we use to understand the world, we are likely to become confused by projecting aspects of our mind onto physical reality. For example, should our suffering be understood as a result of our mind or the world? Models allow us to examine this question with precision, and thereby to deepen our knowledge.
Gnostic models are also models that our mind uses. We would not move without emotions, and we could not move without bodies. However, accurate models of emotions, bodies, and the profound wisdom they represent are fundamental for correctly interpreting our sensations and thus for living well.
