And where are we to learn this? All education and learning and knowledge is acquired, but this one art is a divine art, and man has inherited it. Because he is absorbed in the outer learning he has forgotten it, but it is an art which is known to the soul; it is his own being; it is the deepest knowledge that he has in his heart. No progress in any line that man can make will give him the satisfaction which his soul is craving for, except this one which is the art of life, the art of being, the pursuit of his soul.
