Above linked is a video on the hidden meaning of 13, 23 and 33 to the Masons.
The video begins by explaining that the Compasses is a representational of the spiritual. Think about how it is set at 47 degrees.
Christian = 47; Foundation = 47; Framework = 47; Authority = 47
The narrator says the logo is broken into an M and W for man and woman, with the G represneting the Generative property, or "sex".
Sex = 33; Gnostic = 33; Magic = 33; Masonry = 33; Secrecy = 33; G = 33
This makes the term 'G spot' a lot more significant.
Also, the narrator says domes and spires represent the penis and breasts, symbols of the human beings sexual nature and reproduction.
The narrator then points out that the word 'Man' begins with M, the 13th letter, and the word 'Woman' begins with W, the 23rd letter.
M = 13
W = 23
He then points out the relationship between spiritual leaders and '13'.
I have to admit, B being compared to 13 is interesting. If you don't see it, imagine breaking a B into parts so you had 1 3... see it now? B >>> 13
From there, he shows the significance of summing 13+23+33 = 69
Saturn = 69; Arsenic = 69
If only this man knew reduction Gematria.
Kabbalah is based in reincarnation, so the symbolism of 69 with arsenic also fits in.
When you realize that Freemasonry is based in old world Hermetic knowledge (having to do with alchemy and spirituality), all of this starts to make a lot more sense. Scientifically killing, with purpose, and a belief system in mind.
The dangers of religion, we're living it.
