Knowledge of self ought to be the great project of our lives. Knowing ourselves we will know others. Only by knowing ourselves can we begin to undo the madness we unleash on the world in our wars, our destruction of the environment, our divisions, our desire to dominate others, the poverty we create and exploit. Only through self-knowledge can we reverse the damage we do with all the worldly knowledge we have, which has been only a higher ignorance.
