What is necessary is to develop a sympathetic nature and to sustain its gradual growth. As it is difficult for the student of voice-culture to practice his voice and not to let it be spoiled - for even practice may spoil it - so it is with the sympathetic person: while developing the faculty of sympathy there is a chance of spoiling it. In other words, the more loving a person, the more chance he has to be disappointed. The greater the love, the finer the fragility and the more susceptible to everything; therefore the greater the love, the more fragile the heart - at any moment it can break. The one who walks in the path of sympathy therefore must take great care that his way may not be blocked. It is his own perseverance that will keep him from everything that is trying to block his way.
