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.

A human being is a part of the whole called by us universe, a part limited in time and space. He experiences himself, his thoughts and feeling as something separated from the rest, a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty.
Albert Einstein
