"The idea that it might have been the particular characteristic of being that magical hot-spot from which spiritual energies of the New Aeon burst forth for the planet is at least a reasonable possibility, given other principles. Compare the Islamic practice of directing all prayers to Mecca, no matter where in the world one is located"
This is a good point and it's always the way I pictured it. The Muslim, in fact, faces the "black stone" in the kaaba located in the heart of the Masjid al Haram Mosque in Mecca. By the same token, Thelemites facing Loch Ness are facing the "abstruction" of the Stele of Revealing that (supposedly) once occupied Boleskine House.
I believe this practice goes back to dynastic Egypt, specifically the astonomical temples, which contained an icon of a god that was supposedly charged by the light of a particular star. This energy than radiated out from the idol itself.
Parenthetically, the astronomical temple of Horus at Edfu is the only one in Egypt which still contains its icon.
