The Amazing Circular Number 9
A very interesting point about the number nine is it always "becomes itself."
Multiply nine by anything and add up the digits and they will always come back to nine. E.g. 9 x 9 = 81. (8 + 1 = nine.)
Or take, 9 x 219 = 1971. 1 + 9 + 7 + 1 = 18 and 1 + 8 = nine; and so on.
The number nine will always come back to itself. Just like a circle.
What is even more interesting, is when we add together one through eight, we get 36. 3 + 6 = 9, nine again.
We then add one through nine (1 + 2 + 3 + 4 +5 +6 +7 +8 +9) together and we get 45. 4 + 5 = 9, yet again nine.
The diamond is four lots of 90O, which equals 360O; 3+6=nine again. The square, just a diamond on its side, is the same, nine. The equilateral triangle is 60 + 60 + 60, = 180 degrees: 1 + 8 + 0 = 9, another nine.
If we look at the pentagram, five lots of 36 degrees: = 180; another nine.
The hexagram (Star of David) = 360 degrees: the same story, a nine.
We could go on and on.
The Sumerians divided the precessional period into 12 equal parts of 2,160 (360-day) years, which is of course a nine number.
The Sumerians used a base-sixty form of measurement rather than base-ten - the decimal - to calculate time as it works perfectly with the 360-day calendar.
It is from the Sumerian influence that we divide our clocks into 60 minutes and 60 seconds, which gives a very harmonious interplay between minutes, hours, the circle of 360, the solar and lunar cycles and the larger zodiac cycles.
