Once again, like a broken record, I have to repeat that I have never read Blavatsky or Cayce or any of those. The knowledge IS millenniums old since Pythagoras reported lived 2500 years ago and he got his knowledge from the Egyptians so it is obviously older than that.

I don't know that Blavatsky ever claimed to have received any knoweldge from Egypt. Unless I am mistaken, she claimed she received it from secret Mahatmas in Tibet. It's all crap, of course. The wisdom that I speak of came from sources as the Greeks, Egyptians, Indians and later European alchemists and astrologers who assimilated this older wisdom and wrote about it quite a bit. I'm also a fan of Gnosticism whose writings comprise the Nag Hammadi Library for anyone who cares to read it--you can get it at any decent bookstore.

I have never read about Blavatsky giving a hoot about sacred geometry or its links to music theory which was done by Pythagoras and probably earlier sources than him. A good book on that is David Fideler's "Jesus Christ--Sun of God." Fideler holds a Ph.D. in philosophy and cosmology. If you think this stuff is all bunk, you'll find this book quite eye-opening. Then all the sacred geometry was huge among the medieval and renaissance Christians and it is found in the architecture of their churches and even their bibles.

This is stuff everyone should know.
