I guess I am quite agreeable with your inclusions there, and yes, the descriptions of the a 'door' opening is a powerful scene to arrive at through meditation. I can only imagine a chemically-altered state of mind would make it even more powerful.
But what a strange comparison...a horizontal scene accessed and overcome through a vertical apparition.
About 3 years ago you responded to a post from me about the Akhet, in the topic, 'Yet another Giza Plan :)'. That was the beginning of a dip into a theory that became Opus Mundialis Rostau. At that time, I was using one kind of astronomical depiction that ended up being incorrect. A refinement certainly did a lot better.
Anyway, the entrance feature became an all important piece in the puzzle which identifies the 'horizon' through the pyramid, based upon the level of the dip between the 2 mounds of the feature. This level is the joint of the 20 and 21st courses of the pyramid, and certainly Petrie's survey identifies these courses as being somewhat important, due to their heights between quite thicker courses. This level is the basis for the interaction between the architecture of the pyramid and an astronomical overlay. It is from this that my references to the Sun are made in my previous description.
The geometry in OMR has the Winter Solstice Sun 1 hour before sunrise within the passage intersection; at sunrise upon the horizon above the first girdle stone; and at midday at the height of the topmost relieving chamber. The Summer Solstice Sun is outside the pyramid, but its location at sunrise geometrically translates to the height of the pyramid. If one were to stand some 540" away from the edge of the pyramid, one would be standing upon the spot where the reference to the summer sunrise occurs. One finding in OMR is a proposed hidden area within the pyramid, determined by a few geometry alignments. One of those alignments is correlated by this location outside the north of the pyramid: this spot aligned with the middle of the original entrance goes on to reference this hidden area perfectly, agreeing with the other process of defining this hidden area.
For what I theorise, the entrance feature has a lot to say about this hidden area, so when 'Akhet' is being weighed for its value, there are several layers to it...especially when the entrance feature depicts Khufu's Pyramid in the bottom left of the feature.
The ritual and mythology of the AEs seem to hint at more that went on within the pyramid and of the pyramid instead of just recalling the good 'ol days.
