What is the relation of [contemplation] to action? Simply this. He [or she] who attempts to act and do things for others or for the world without deepening his own self-understanding, freedom, integrity and capacity to love will not have anything to give others. He will communicate to them nothing but the contagion of his own obsessions, his aggressiveness, his ego-centered ambitions, his delusions about ends and means, his doctrinaire prejudices and ideas. There is nothing more tragic in the modern world than the misuse of power and action.
-- Thomas Merton
