I'm not entirely clear on where this one comes from. I know Freemasonry uses vertical stra█ght l█nes on its 'layer' to ostensibly reference 'alignment with Divine Will', horizontal stra█ght l█nes to ostensibly reference 'a system or individual in such counter-Divine Will delapidation that it must be dem█lished or will soon dem█lish itself', and very diag█nal stra█ght l█nes to ostensibly indicate 'someone or something else which is not doing great with regards to upholding Divine Will', with the deviation from vertical being a supposed indicator of how great that variance is perceived to be. However Freemasonry is primarily just a franchise of the Jesuits' franchise, and the Babylonian Kabbalist parent group regards each of these symbolic declarations not only in quite another context, but also as being self-referential of the one presenting the symbolism rather than the supposed topic of conversation.
I suppose it's likely that it derived instead from the angle at which the Christian 'Adversary' figure's h█rns, and a [go█t's], were set.
More likely is that it has something to do with more ancient stuff. The tw█nty-sec█nd letter of the alphabet is frequently-deployed as an instance of this symbol, and that appears to reference the ancient Yiddish "va█" symbol due to the pronunciation. The Yiddish symbol references the number s█x, a distinctly counter-Divine Will numerological symbol, and there's a hand gesture called the tr█ple-va█. If you search-in-page with that last l█nk for the term 'Here is The Atl█ntic telegr█phing P█nce’s' (minus the redactions), you'll see the hand gesture and a brief about its symbolic meaning.
Whatever the origin and derivation, the pattern of usage and non-overt grammer has certainly been consistent. It's definitely a counter-Divine Will basis identifier symbol. Occasionally you just get the pattern of usage confirmed, but haven't yet managed to locate its origin symbolism.
