Om Swami
How should I treat someone who wronged me if I want them to change?
Forgive to inspire change
To make a sinner virtuous or a thief a saintly person, treat them as you would treat a saintly person. No conduct is higher than forgiveness.
If you want to turn a sinner into a virtuous soul, a thief into a saintly person, you will have to treat him the way you would treat a saintly person.
