Premanand Maharaj Ji
How do I stop bitterness toward someone from returning during bhajan?
Walk away from quarrels
Desire gives birth to raag and dwesh (attachment and hatred), so stay alert to both. When a quarrel comes, fold your hands and walk away to protect your mind.
If a chance for a quarrel or fight comes, fold your hands and walk away. Do not quarrel. By this your inner state will be saved.
