Thanks a lot, Rawn. I need to meditate on that chart - I don't know how much time I have spent at that website and that chart just passed me by. Just from looking at the subdivisions of the Physical Plane, I have some questions, but I don't want to wander off into Alice Bailey land unless you think this specific subject links sufficiently with Bardon's teachings to warrant it. In the meantime, you've supplied me with some food for thought; thank you :-) All the best, Martin
