"It strikes me as really quite odd that you would consider a treatise on life, healing or anything else to be spurious because it borrows techniques from various cultures and traditions!"

Further to that, we 'borrowed' numbers as we know them (deca system) from the middle East (and the alphabet, too); astronomy from the Italians who got it from the meddle East and the Egyptians; medicine from every country in the world--Ooh-Aah, who the hell do you think other cultures ARE. They are us for crissake. All of us are us. All. Do you have your world wrapped up in white hats and black hats? My gawd, read something other than what you do. You get anymore narrow minded and you'll be letting your brains flow through a straw. There won't be a friction coefficient.
