One must never think that exercises are only for the beginners. They must know that Paderewski is playing simple scales as a beginner would play on the piano, and he plays them oftener than a beginner would play. Therefore never think that in order to advance spiritually you must have other practices or new practices. That is not necessary. If you continue every day the practices that you have, especially when you are here, it will be of great help. Besides that, there is a certain attitude of mind that is necessary while one is in the Summer School. That attitude of mind is such of friendliness, sympathy, tolerance, forgiveness; an attitude to tolerate, to forgive and forget anybody's faults. We are all limited, we all have our faults and limitations. If another person has a little more, perhaps our faults are hidden. Maybe we have more faults than anybody else.
