"As Above So Below" Explained
I like how Russianvids pointed out Freemasonry is all about duality. The twin towers coming down on 9/11 is a good example of Freemason duality. Also this is mockery of the bible.
Also the signs at the WTC memorial inform you to walk around it in a counter clockwise motion just like the cube in Mecca.
This is considered worship of apollyon (Rev. 9:11). Revelation 9:11:
And they had a king over them, which is the angel of the bottomless pit, whose name in the Hebrew tongue is Abaddon, but in the Greek tongue hath his name Apollyon.
