Compassion literally means to feel with, to suffer with. Everyone is capable of compassion, and yet everyone tends to avoid it because it's uncomfortable. And the avoidance produces psychic numbing -- resistance to experiencing our pain for the world and other beings.
Our meditation should begin with the realization of our NOTHINGNESS AND HELPLESSNESS in the presence of God... "Finding our heart" and recovering this awareness of our inmost identity implies the recognition that our external, everyday self is to a great extent a mask and a fabrication. It is not our true self. And, indeed, our true self is not easy to find. IT IS HIDDEN IN OBSCURITY AND "NOTHINGNESS" at the center where we are in direct dependence on God.
