420 is initially three numbers: 4, 2, and zero.
start with number 4.
4 = yang within yin/yin within yang.
the end result of this harmonic convergence is the tai chi, and thus 4+1.
5 comes before 4.
you start at 5 though its not really a start.
4 & 2; even numbers.
in between is the number 3.
2 = yin/yang but harmony brings them together to give birth.
thus, the number 3; it is the child of male and female.
but everything stems from one.
the numbers between 2 and 0 is 1.
and one thing is birthed by the no-thing, or the mysterious womb.
the zero at the end is reflective of the no-thing, which isn’t nothing.
so the even numbers 42 are visable. 0 fits in when you take a look at:
the invisible odd numbers, obviously, are 531 and signify what comes together.
this makes the invisible the mark of harmony.
.
an argument can be made that between 4 2 0 is merely 3 and 1 and that 5 is not neccesary.
but 5 is the tai chi; its what is born when yang within yin & yin within yang come together.
to back me up, i offer the following:
once 4/20 ends, there are 41 days in order to reach 5/31.
4+ 1 = 5.
(no references used to create this model, though i may not be the first to ever discover it using logic + numerology which is the number 2 that creates 3, an expression of tao)

wow thats was a lot to take in this far into 420 lol
So, How do I get to the Gallery?
