Recognise good and evil is born.
Is and isn't produce each other.
Hard depends on easy,
Long is tested by short,
High is determined by low,
Sound is harmonised by voice,
After is followed by before.
Therefore the Sage is devoted to non-action,
Moves without teaching,
Creates ten thousand things without instruction,
Lives but does not own,
Acts but does not presume,
Accomplishes without taking credit.
When no credit is taken,
Ku yu wu ksiang sheng - Lao Tzu
