1. "In fact, as human beings, we are by nature social animals, and our happiness and even survival depend upon our interaction and cooperation. So when positive emotions guide intelligence, it become constructive. The warm, compassionate heart is the basis for peace of mind, without which the mind will always be uncomfortable and disturbed."
