Premanand Maharaj Ji
How can I stop a break-up or someone's betrayal from hurting me so much?
Pure character, Naam jap and dharma: others' pain won't affect you
Keep your character pure, listen to Bhagwan's leelas (divine deeds), chant the Name and walk in dharma. Then pain given by others will not affect you.
So if our character stays right, and we listen to the divine leelas of Bhagwan, chant the Name and walk in dharma, the pain given by anyone will not affect us.
