I couldn't watch a video because the internet in DR was so bad. It was about an interview where a woman asked Thich Nhat Hanh (famous Buddhist monk - as famous as Dalai Lama) about how to help mentally-illed people with very disturbing minds. She said when a patient was practicing Buddhism to control his mind, he was better and able to control his mind but sometimes fall to his delusion.... but still better than when he was on medications.
gotta try to find it.
