Has anyone ever asked themselves why a war memorial nearly always has to be an obelisk? And why do you think the Washington monument in the centre of Washington DC is a giant obelisk? Because obelisks, like all these symbols and geometrical shapes, generate the energy they represent.
What a symbol is built to represent is the energy it will generate, because symbols are a physical manifestation of the thoughts which create them. Rulers of The State don't put their symbols everywhere just for fun. They do it because it helps to resonate the energy field to the vibrational frequency they want. In turn, this affects the thoughts and feelings of the people.
