I don't believe these evil people give you and I clues to discover them by so much of this is simply not true. However, some of is evidence of mystery school kind of teaching. Take the star of David. It's two deltas, actually. They are entwined but a single delta with the point going up like this A has one meaning. Then you are given the secret key and then the same delta is viewed with the point down like this V and this gives it a whole new meaning. these things are carefully taught. Then at some point, another secret key is given and the two deltas are viewed entwined like the star of david and that has another level of meaning that only sume secret master understands. It's how symbolism is used to train people to remember these secret teachings accurately. they are memory aids but when you see them, if you know what to look for, you may recognize them. Let's make something up just so you understand what I'm saying. Oh dear wife has "activity suggestions" for me so I'll have to do this another time.
