Expression or equation?

I can see the universe as a mathematical expression. Something that is. The equivalent to a number, to a given (though sometimes unknown) value.

I can also see the universe as a mathematical equation. A balance. A set of scales. A riddle that could be, perhaps, worked out.

The first view stresses the result, the second one focuses on the process. Both are beautiful.

"Light descends through 6 and ascends through 8", I was once told, by someone who had read about sacred architecture.

The expression will always point to number 1, which is closely related to the hexagon (6) because the radius of the circumference is also the side of the six-sided regular polygon.

The equation will, I believe, change in time, according to my level of understanding. I may start out with a polynomial function, go through a phase of inequations, then dive into systems with three variables... This "building up one's structure towards unity, in small steps" is very much the feature of number 8, the octagon, the octagonal support for domes in churches.

6 or 8, all is 1. And 0 is everywhere and nowhere.
