I tied it all together for you in the Waldorf Education thread.
That thread stems from two books I have, "The Book Of Thoth" and The Child's Changing Consciousness.
Now there are hints of the Genesis Strategy, Collapse, The Path of The Masters, and even some Her Bak. And many others.
I used to deal used books online. Still do a bit. I've sold over 10,000 books in the last 7-8 yrs, and skimmed them all. Kept the ones that interest me, or have future value.
But by far, the best research tool is the internet. Millions of books out there.
