For instance, when doing physical culture exercises it is not necessary to be more strong. Some will suffice the purpose for your whole life. The same thing in singing. The same exercises perhaps which a beginner must do, the same are done by Caruso. The greatest singer will do the same as everybody else. Paderewski will play the same scale which a child begins to play. He will never be tired of it. It is the most necessary thing. The same with spiritual practices. You must not think addition to this means development. You must think this will take you further and further and will again be of the greatest importance.
