the ideas behind the esoteric understanding associated with symbolism is an absolutely massive subject that could take literal volumes to properly describe and is probably too complicated for this restrictive medium..
example - start with the triangle
△ - him (3)
▽ - her (7)
triangle in hermetic numerology
triangle
75511725 = 33 reduced equal 6
33 is quite the number jesus died(5) at 33, performed 33 miracles, etc...
interesting enough when jesus started it was in bethany (6)
when him △ and her ▽ get together (the marriage) you would get the star of david ✡ which then can produce an ascended master(9) known as jesus, krishna, zeus, zion, plus more...
even the 666 is hard to understand for most... 6+6+6=18=1+8=9
jesus
45666=27=9
4 is a hint at the tetragrammaton
5 is a hint at christ
666 is the number of the father (him)
google was named google for a reason to be sure however trying to explain the number 7 would be way more difficult than trying to explain the number 9 or the number 666 and why they are the same yet different.
the g in the freemasons logo = 7
google
722725=25=7
7 = satan, moloch, adam, her
i could literally type all day and you probably still wouldn't be able to grasp the concepts...that said, if you are interested i would post a gematria table and show you the basics so you can start to learn the numerology associated with the understanding, it is where all initiates start ...
