Companionate love tends to grow and last. It is a willingness to be kind, generous, affectionate, giving and nurturing to others that transcends concern for what one receives in return. It is unselfish, and empathic. It requires wisely planning and setting limits. One cannot give away one's own livelihood and self esteem for others or there will be no resources with which to help others.
Universal love requires wisdom and a willingness to take risks for the sake of benefitting others.
