“It does not touch one who does not touch,
But then will touch the one who touches.
Therefore it touches the one who touches,
The one who wrongs an innocent man.”“If one wrongs an innocent man,
A pure person without blemish,
The evil falls back on the fool himself
Like fine dust thrown against the wind.”
