Often a fine person has jarring influences from around, from those with whom one comes in contact, one's friends, one's enemies; everywhere one finds life most difficult. If one goes on like this it becomes nothing but a terrible life; one becomes irritated and one becomes a difficult object for others. But by attaining that strength which comes from the deeper side of life one is able to get above things, to overcome the influences which come up and jar one's sensibilities. They are all thrown back, and one can keep oneself in the right tone and rhythm. The purpose of life is to keep oneself in the right tone and rhythm.
