Empathy

Explanation:

Empathy is a term of positive psychology. It enhances the person well being. Empathy is an experience of a person in which a person understands another person feeling, thought, condition from her/his point of view. We can say that to "emphasize the feeling not sympathize". It is a experience that facilitates a person's pro-social behavior from inward not by forced. So people can help other people from their core of heart. Contrary to sympathy which means to feel sad for another person, empathy promotes well being and selfless compassion for a person. This sounds like a positive,  prosocial behavior and well-principled practice for a person. But too much empathy can affect a person's decision making power and person just think from their heart, not from their heads.
