Two fully triangles, one with the tip facing upwards, the second with the tip downwards. Who does not know the Star of David or the Esagram? Known as the "Seal of Solomon", it is an ancient symbol. For many it is associated with Jews, in Israel, to the point that today the air forces of this state lead this symbol on the wings. In reality, this is a sign from the cabal meaning very clear of the union and low union of the heavenly and earthly, the world of men and that of the gods. "How in heaven as on earth" says the Paternoster and has the same meaning this six-pointed star. Known since Babylonian times, always has a positive meaning, the union said, sharing sacred with the profane. But not all conceive the Star of David with this meaning: associated by Inquisition to Hebraism, was seen as satanic mark and who was found in possession of an object with this symbol was punished as a heretic. The masonry in the eighteenth century put it and some, like David Icke, saying that the plant in the city of Washington DC, the capital of the United States, had this form (for the joy of Zionists). In modern times allegations of esoteric scientists have tried to give fanciful assumptions about the genesis of the symbol, indicating it as a metaphor of penetration by male to female. In reality, the sexual sphere has nothing to do with the events divine: Esagram wants only mean what they show, which is the union between two worlds, a union seen as sharing and non-possession.
