Empathy teaches this lesson; it is one of the feelings we are put on Earth to learn, a key aspect of our preparation for immortality. It is difficult lesson in that we must experience it not only in our mind but in our physical bodies, and in the mind and body we have pain, dark emotions, difficult relationships, enemies, loss and grief. We thus tend to forget others and concentrate on ourselves. But we also have love, beauty, music, art, dance, nature, and air, and we long to share them. We cannot transform negativity into the positive without empathy, and we cannot truly understand empathy without experiencing it in our present life, in our past, and in our future.
