>Saturn
Saturnius, Set, Satan, Lucifer, take your pick on what god you think Saturn signifies, but it's Satan. Prince of Darkness, the Great Deceiver. It's his planet, look up the "Saturn Square" for a greater understanding of the 666 phenomenon.
666, 777 and 888 are powerful numbers for a reason. 666=18, 1+8=9, 9 is both the "NO"thing and The All at once, 9+any other number=that number when broken down. 1+9=10=1(1+0), etc. However, 1+2+3+4+5+6+7+8=36=9(3+6), thus 9 is all and it is also nothing. 666 is the mark of the beast because it lacks True evolution, True Awakening. It is illusory in nature.
777 make 21, 2+1=3, 2+1 also signify the Trinity. The Sacred Masculine impregnates, typically a powerfully archetypal Sacred Feminine, who gives birth to the Sacred Masculine Hero figure who will go onto redeem that society. It's allegorical, it's a reference to your Left Brain(Logic, Masculine, Dominant energies) and your Right Brain(Intuitive, Feminine, go with the flow moreso than actual submission.), the combined use of those forces creating the sacred masculine child(Wise and Informed Action), thus, 777 is the pinnacle of what Each of Us may seek. 888 is Infinite, it is all things, it is God itself. Man cannot be infinite, nor can he posses eternity. Man can only seek to act with Wisdom, Courage and Understanding in this life. 888 is not meant for us.
999 is the penultimate illusion, when your delusions go so grand, you've lost sight of everything. To go "beyond" god in a sense, into the Nothing.
>Star
In the Tarot, the Star is meant as a signal to change. It could be a small change, it could be a large one. It signifies a change in perspective, it often is meant as a little warning, to be prepared.
>Pyramids
The entire functional nature of a Pyramid structure is very simple and once understood, you'll realize why our society is structured like one.
A pyramid does one thing and one thing well. It concentrates energy into the pinnacle. Think about your employment, or government, or hell, any hierarchy. Because of how blindly we listen to authority figures, it leaves us extremely vulnerable to these kinds of tactical subversions. If you use what we call "Compartmentalization", you could have millions of unknowing citizens working on some SUPER high tech shit that they can't even begin to really understand, while keeping them COMPLETELY in the dark, except for a small select group of people who ultimately assemble these odd little pieces together into a working model.
Pyramids concentrate power, that's the point. In the Land of the Blind, the One Eyed Man is King.(All Seeing Eye+Pyramid explained.)
I'm afraid you're on your own for the helmet/left right thing
