When deep wounds exist between people, resentment often lingers even after apparent reconciliation. This teaches me that forcing forgiveness doesn't truly heal. The sage keeps accounts but doesn't demand payment. The way of heaven helps those who are good without favoritism. In my life, when I've been hurt deeply, I can't simply force the resentment away. I need to let time and my own spiritual practice gradually dissolve those lingering feelings.
When a reconciliation is effected (between two parties) after a great animosity, there is sure to be a grudge remaining (in the mind of the one who was wrong). In the Way of Heaven, there is no partiality of love; it is always on the side of the good man.
