With all of these symbols, there are many levels of interpretation. To the outsider/early initiate, these symbols can mean 'peace' or 'love' or whatever, but those with higher levels of understanding know more about the symbols, and the powers behind the symbols. Quite often, the higher levels of understanding bear little resemblance to the lower levels of understanding.

“Some even believe we (the Rockefeller family) are part of a secret cabal working against the best interests of the United States, characterizing my family and me as ‘internationalists’ and of conspiring with others around the world to build a more integrated global political and economic structure – one world, if you will. If that's the charge, I stand guilty, and I am proud of it.”
