Binary recursion, or dualism, leads us in circles as it is circular as one thing leads to another then back, everything repeats. From this everything resulting from it is an endless cycle which becomes obscure when observing it from the single position of it being "everything". This obscurity occurs because everything reduced to a cycle makes the cycle mean many different things thus our definition of cycle becomes fragmented and with it the whole of language.
You need to see that cycles need not be circles,
they can also be spirals, which when closely knit can
appear as circles unless you look closely at them
and see that repetition is almost never exact.
There is a fundamental problem with dualism however,
in that if it was absolute, the two extremities would
never be able to have contact with one another.
Which obviously they do or we would not be able
to compare the extremities of the dichotomy.
That is why duality always has a dominant half.
Shadow is the absence of light, because
light is dominant existentially.
Light is not the absence of shadow - shadow is the illusion.
If we compare the dualism of mind-body (or spirit-world)
we need to then appreciate that one of them must be
the intrinsic one, the other is the illusion.
However, for practical purposes dualism has far more
utility than the monad (non dualism).
Most dualism is a 49% - 51% split.
Its impossible to not abstract the shadow as non-existent.
(We must abstract the shadow as having psychological realism to it).
Ironically, those positions (duality vs monad)
themselves form a duality.
So we can never get away entirely from either the duality
or the monad - but again - that is a dualism.
And that is the form of a spiral.
A spiral is actually a trinity - we need an x, y, and z to describe it,
mathematically.
