.you could possibly rewrite the sudoku puzzle, using letters, i.e., to replace 4, 6, 8, 9... with D, b, B and P... alternatively the lowercase b with Q.


.                          i really have to stop borrowing
               from the Zen concept
of ensō - with what the "circle"
represents -
   namely? heihō, i.e. the "square" -
namely, what comes after
absolute enlightenment,
strength, elegance, the universe,
     and mu (the void) -
i.e., alternatively: the nu, or?
  the filling...
            heihō is an elevated noun
denoting a sudoku puzzle...
  
   it begins with the key and lock
analogy, borrowed from greek:
Φ (insert the key)
       θ (turn it, open the door,
   and subsequently enter) -

all sudoku puzzles begin like so...

    □ that becomes Φ, θ
   that becomes #
    that subsequently becomes ■ -
   after many instances of
   —, |, / and \ considerations...

this idea only came to mind,
bothered by an obstruction
on the 10,050 puzzle...

0    0    0
0    4    2
1    3    9
2    7    5
4    6­    8
8    9    4
3    2    0            } these three blanks
0    0    7                    i was concerned with...

                          1   0   0
                          0   0   5
                          0   6   0
                      __
                          x  ­ y   z
                      __
                    (    6   ­ 5   1  )
                    (    5    1   6  )
                    (                1 )   ****... no alternatives...

and given there's a fractional choice,
conundrum, i.e. there are only
two viable choices?
      well? neither.

the solution? i had to be patient with it,
after all, it's akin to Zen "circle"
concept, namely?
  you can't make a mistake -
given you're using such, "primitive"
tools as a pen on paper...

5     8     6     4     3     9     2     1     7
7     4     2     1     6     8     3     9     5
9     1     3     5     7     2     8     6     4
1     3     9     7     2     4     5     ζ     6
2     7     5     3     8     6     9     γ     1
4     6     8     9     5     1     7     3     2
8     9     4     2     1     5     χ     7     3
3     2     1     6     9     7     4     5     8
6     5     7     8     4     3     1     2     9

yet this wasn't the pinnacle of
the evening...
   some "madwoman", singing,
in the night... the most beautiful songs...
it was hard not to listen,
given she went on for about 3 hours...
kept singing and singing...
sometimes giving
   a frivolous explanation to someone
trying to interrupt her...
    a woman in love...
    just kept singing and singing...
     defiantly english -
i can't recall the last time
i heard a woman sing so beautifully -
not armed, standing behind
a microphone, on a stage -
   with a band behind her...
this girl's voice had but one stage:
the night -
   and her backing band?
         simply the moon;
and an appreciative audience of one...
moi.
