From the little I know about the Mystery School (Babylonian system) which uses the 5 elements Earth, Fire, Water, air and Spirit. The Pentagram is a representation of these 5 elements. They are paranoid with "balance" Good and Bad. The Y symbol is a Pentagram pointing down ie. towards the bad. So the symbols that these psychos would worship would be the inverted pentagram. Baphomet, is one such symbol.
