Premanand Maharaj Ji
How can I stop hating someone who does wrong things?
Hate the wrong, not the person
Don't hate the person who behaves badly; grow affection for him so he himself comes to hate his bad conduct. If he comes to hate the bad conduct, he becomes a good person.
So we should not hate the one who behaves badly. We should grow our affection for him and help him come to hate his bad conduct. If he learns to hate that conduct, he will become a good person.
