Premanand Maharaj Ji
How should I behave with people who insult me or wish me harm while I follow the path of bhakti?
Answer abuse with good wishes
On the path to Bhagwan, the training is to wish well for whoever abuses you, honour whoever insults you and do good to whoever wants to harm you. This is what sets you apart from them.
If someone abuses you, wish them well. If someone insults you, respect them. If someone wants to harm you, do good to them.
