In order to have compassionate relationships, compassionate communication and compassionate social action, there has to be a fundamental change of attitude... The basis of any real kind of compassionate action is the insight that the others who seem to be out there are some kind of mirror image of ourselves. By hurting others, you hurt yourself. By making friends with yourself, you make friends with others.
To acknowledge our ancestors means we are aware that we did not make ourselves, that the line stretches all the way back, perhaps to God; or to Gods. We remember them because it is an easy thing to forget: that we are not the first to suffer, rebel, fight, love and die.
