As with all things occluded and mysterious, the power never sits within obvious seats or places. The Egyptian mystery schools adhered to this dogma, not only by building into its architecture astral reasoning. But by occluding the true power of rite into the isolated interior, far from the pomp of the delta.

Alexandria and Bubastis held knowledge of the physical plane. The main libraries as repositories as sums to material knowledge. The entire delta region as it' appellation of the Lower kingdom denotes was a place of collection and trades.

The duality of Lunar and solar time was presented most directly as the delta, plexus of the Nile, was suggestive of Lunar cycles of inundation and other tidal phenomenon. As the initiate was lead into the interior the literal ravages of Solar influences became apparent by the tides of Sand and desert.

This was a literal manifestation of accretion and entropy.

These extremes also typified the polar extremes of spirit over material being by the lack of material sustenance available in the sere of desert. Far from the bustle of cosmopolitan Egypt lay the initiations in the semi divine planes within the Elephatine and Edfu. Abu Simbel, on the border of present day Sudan, brought the secrets of the divine.

Today these remote outposts are located on the manmade Lake Nasser.
