In the orchestra there is a conductor and there are many who play the music; and every player of an instrument has to fulfil his part in the performance. If he does not do it rightly, it is his fault. The conductor will not listen if he says he did not do it properly because he was sad or because he was too glad. The conductor of the orchestra is not concerned with his sadness or his gladness. He is concerned with the part that the particular musician must play in the whole symphony. This is the nature of our lives. The further we advance in our part in this orchestra, the more efficiently we perform our part in life's symphony. In order to be able to have this control over oneself, what is necessary? We must have control over our inner self, because every outward manifestation is nothing but a reaction of the inner condition. Therefore the first control that one has to gain is over one's own self, one's inner self, which is done by strengthening the will, and also by understanding life better.
