As you know, on 9/11/01, transiting Neptune was at its Origin of Islam degree (6AQ+, a Neptune Return) and conjoined America's natal South Node, a karmic synchronicity with a Saturnian undertone of loss, separation, and Neptunian intrigue and showing a basic disharmony in the spiritual realm between Eastern and Western cultures.
Remember after the attacks of 9/11 how spiritual many Americans became? TV ads became more...sensitive. How sad that the improvements haven't lasted better than they have as our old materialism has again asserted itself as Wall Street's greed and a morally corrupt system remind us each day. Actually, America's natal horoscope (Sibly: 5:10 pm LMT) shows Saturn (10th H) and Neptune (9th H) flanking Midheaven (The Goal) = wavering between materialism and idealism. (Ebertin.)
So here's an article from the excellent History Today which explores whether the roots of ancient Islam may be explored and better understood in much the way Christianity has always been and I hope you'll check it out!
