Where then is progress? If any of you, withdrawing himself from externals, turns to his own will to exercise it and to improve it by labour, so as to make it conformable to nature, elevated, free, unrestrained, unimpeded, faithful, modest; and if he has learned that he who desires or avoids the things which are not in his power can neither be faithful nor free, but of necessity he must change with them and be tossed about with them as in a tempest, and of necessity must subject himself to others who have the power to procure or prevent what he desires or would avoid; finally, when he rises in the morning, if he observes and keeps these rules, bathes as a man of fidelity, eats as a modest man; in like manner, if in every matter that occurs he works out his chief principles as the runner does with reference to running, and the trainer of the voice with reference to the voice- this is the man who truly makes progress, and this is the man who has not traveled in vain.
