A Different Heart

The Torah said לא תשנא את אחיך בלבבך - Don't hate your brother in your heart. This can mean the following: Sometimes, people wrong you and hurt you and you think "I would NEVER do that to him. I don't have the heart... How could he do that to me??"

The Torah therefore teaches - Don't hate your brother WITH YOUR heart. Don't hate your brother because he treated you in ways that your heart would never allow you to treat him. His heart isn't your heart.

[The Rebbe Shlita in the name of earlier Chasidim]
