Much of the symbolism is Judaic in original and relates to the Old Testament, with some Egyptian stuff added - or maybe the reverse is the case. It is often said that Masonry originated in Egypt, and with the suggestion that the Aryan Mysteries were stolen by the slaying of the Egyptian Priest-King this makes some sense.
What I suggest here is that these mysteries were once Aryan Mysteries and that the Hidden Hand of the Dark Forces stole these Ancient Mysteries and subverted them to their own ends. In other words they may hold some hidden truths, but that the symbolism was changed to suit an Evil Priesthood who sought to dominate the Earth through the use of Masonic Lodges.
This is a Masonic Symbol on a sash which reminds us of the 'Google Mail' symbol which features on their email service. This again features the 'Triple Tau' symbol at the top, and the 'M-Envelope' is exactly the same symbol as G-Mail. Indeed, here again we have the Solar 'G' in this very name - G-Mail! These people are so certain of their total power that they now show us their symbols openly! Indeed, the name 'Google' is the slang term related to using the eyes - the Great Eye! Google is the Global Company that has been responsible for 'coordinating' individual information which can be easily monitored - 'Google Plus'.
When I went through the Shamanic Initiation back in the spring of 1997 I was watching the TV with my family and could at one point see letters moving across the screen, letters which no-one else could see! Over and over I said that I could see 'subliminal' letters but no-one else could see them. They were very much like the above 'Occult Symbols' which are a Masonic Alphabet. These are obviously a Secret Code, simple but containing (once again) 26 letters like the normal English Alphabet.
