The further one goes, the more difficulties there are; one finds greater faults in oneself as one advances along the spiritual path. It is not because the number of faults has increased; but the sense has become so keen that one regards differently faults which formerly one would not have noticed. It is like a musician: the more he advances and the better he plays, the more faults he notices. He who does not notice his faults is in reality becoming worse. There is no end to one's faults. To think of them makes one humble.
