Here are some pretty interesting diagrams by Greek researcher, George Kavassilas. I believe he created those diagrams even before the Wes Penre Papers were written, or perhaps during the same time period.
He's got a Gnostic worldview, for sure, and the diagrams are showing things quite well for those who need a visual to conceptualize this (which includes most of us). It's not exactly the way I perceive it, but close enough. Diagram no. 2 is drawn from the perspective of a pregnant Divine Mother. (Click the pics to enlarge).
