I know that the greeks and or babalonians used to mint coins with the magical square for the sun on the backs of them, the solar square for the sun is a total of 36 numbers, when the mantra for the sun square is vibrated everyday, the corresponding number of times the person will build their own power and absorb the energy of the sun into them. the numbers if added up total 666.
the square has a special snake like order that you must navigate it in bottom right to bottom left, up a row and then to the right side again,then up a row and to the left, this is one way to do it,
you can also do the square starting at the top right and snaking your way down vertically instead of horizontally.
the table/square is arranged so that when you do the square horizontally, and you change rows you see the numbers sometimes progress in chronological order , or if don't vertically you see numbers nearly mirror one another on the outermost top and bottom sides give or take 1-2 but the pattern Is definitely there.
I haven't really looked at it ad tried to figure it out in any way, I'm just not a mathematical genius like some people when it comes to recognizing hidden patterns and such,
but I can say that it appears to be arranged in a very SPECIAL manner, and I'm confident in the power of the workings.
so that's one place the number 666 comes up.
also 666 in (Chaldean numerology I think) is 6+6+6 which comes out to 18, which in numerology is further simplified to 1+8=9
9 is the number for the sun,this is why the rosary has 9 beads for vibration on it, it is for doing solar mantras like raum, or suryaye. the solar plexus CHAKRA not the actual chest bones is located right below the sternum and the energy of the 3rd/solar chakra is very much like the energy of the sun. that is why its called the 666 chakra,also it has that name because 666 is associated with the beastly devil(the one Christians think is real) and the 666chakra is a beastly powerful chakra,the most powerful chakra for someone who aligns and works on their chakras in the most positive way. in a satanic way
so 666 is important in pertinence to the sun in that way aswell
unfortunately our joyofsatan forums where all of our high priests have their sermons posted has been recently jewed(shut down) so I cant go back and check but I have also read that an exact measurement value of the sun,i cant remember exactly what the measurement is of,comes out to 666.(something).
"satan" as you put it in quotation marks exists, and this is not the board for those trying discredit the joyofsatan,does not encourage "knowlage" as you say, but he encourages LEARNING. just know that when you ask questions like this you take up the time and energy of those who are dedicated Satanists here, so if you are capable and think you can hint that most here are uneducated and expect people to take kindly your wrong. so I urge you to take your skepticism and go do research for yourself,
the jos definitely talks more about the significance of 666 then you have seen,and its dumb to assume you have seen and read everything because you obviously haven't or you would know more than what you wrote above
"other than JOS saying vaguely it is in relation to the solar plexus."
then trying to slap us in the face with your "I thought satan ?!!!" remark.
you should read the entirety of the joyofsatan website before you come here with more questions
good luck and HAIL SATAN
