0 is not a “number.” 1 is the only real number. “Numbers” 2-8 are counting designations.

The system sums to 9. 9 = 0. All other “numbers” sum to single digit representations.

1+2+3+4+5+6+7+8 = 36

3 + 6 = 9 = One

The 1 is the seen, and the 9 the unseen. The first and the last. The beginning and the end. These two are one.
