Premanand Maharaj Ji
How do I stay kind to a suffering person who is rude or abusive to me?
Treat the suffering like your own child
A person in pain may speak harshly, so treat him as you would your own child. Hold back your anger and keep helping, and Bhagwan's grace will be on you.
Your duty is to remove that patient's suffering, even if he abuses you, even if he criticises you, even if he spits on you.
