Tao Te Ching Chapter 79
Patching up a great hatred is sure to leave some hatred behind.
How can this be regarded as satisfactory?
Therefore the Sage holds the left tally,
And does not put the guilt on the other party.
the virtuous man is for patching up;
The vicious is for fixing guilt.
But 'the way of Heaven is impartial;
It sides only with the good man.'
