I have heard a story of a Peace Pilgrim, an American pilgrim and ascetic, who managed to heal one sick man through conversation. The man was suffering from general degeneration of health and doctors couldn't find the cure. Through the conversation with the sick man, Peace Pilgrim discovered how he was holding anger over his brother his whole life. She somehow managed to explain to the sick man why his father couldn't afford him college education and why his brother got it instead. At the end, the man released anger and his health suddenly improved. He got cured.
How can philosophies be used for healing people with mental issues? Can an ontic conversation bring about a proper perspective in the mind of a mental patient, which would naturally lead to emotional release and increase of well-being?
