Scrying the aethyrs - change at NIA, why? Options

When scrying the aethyrs from TEX to NIA, there seems to be a fairly steady line of developments in which you could almost write a continuous story from it, but it changes when you get to NIA, I have been trying to understand why before I proceed.

Will it only become clear after I proceed?

Does it seem to change a lot for everyone at NIA or does the story change for some people on other aethyrs?

Is it different each time you start the journey from TEX?

Would prefer answers from members who have actually done this rather than mere speculation please.

I discovered Enochian alittle over 25 yrs ago and felt very comfortable with it. Who knows? I had the good fortune to take some classes on the subject from Simon (of Necronomicon fame) and have worked with it on and off over the years. Life of mundania intruded along the way and before you knew it I was on the downside of good health. This, in particular, stymied alot of astral workings due to a heart condition. Feh! I will work through this, one way or another...
It was told to me (and I find this so from actual work) that there are 3 main barriers, if you will, that one comes to whilst Rising on the Planes/Aethyrs. At NIA is the first, where one leaves the astral and progresses into the Mental Plane. It is considered an Initiatory barrier equating with the Grade of Philosophus and the ability to move through time and space astrally. Its corresponding sephiroth is Netzach(Venus). I would try the ritual of Rending the Veil to project past this spot. With this will come a feeling of great freedom (of movement).

I have utilized the Schuelers books on Enochian as guides and they seem to be right on the money! I'd love to peruse Rankine/Skinners book though....*sigh* money is a problem...but what the hey... I'm also noodling around with the Liber Scientifea (sp?) as outlined in the Aurum Solis papers by Denning and Philips. Great inspirations! (IMG:style_emoticons/default/laugh.gif)
