I have read that youth is full of enthusiasm and ideals, and that these gradually disappear with age, until a man is left with few or none. But it seems to me that enthusiasm, if real, should not die out, and leave cynicism behind, but rather should become stronger and more purposeful with age. The young children coming straight out of the heaven-world have brought with them a feeling of unity, and this feeling should be strengthened in them, so that it may last on through life. Anger and irritability belong only to the separated self, and they drive away the feeling of unity. Self-control also involves calmness, courage and steadiness. Whatever difficulties the teacher may have either at home or at school, he must learn to face them bravely and cheerfully, not only that he may avoid worry for himself, but also that he may set a good example to his boys, and so help them to become strong and brave. Difficulties are much increased by worrying over them, and by imagining them before they happen--doing what Mrs. Besant once called, "crossing bridges before we come to them." Unless the teacher is cheerful and courageous with his own difficulties, he will not be able to help the boys to meet _their_ difficulties bravely. Most obstacles grow small before a contented mind, and boys who bring this to their work will find their studies much easier than if they came to them discontented and worried. Courage and steadiness lead to self-reliance, and one who is self-reliant can always be depended on to do his duty, even under difficult circumstances. Self-control as to the mind also means concentration on each piece of work as it has to be done. My Master says about the mind: "You must not let it wander. Whatever you are doing, fix your thought upon it, that it may be perfectly done." Much time is lost in school because the boys do not pay sufficient attention to their work; and unless the teacher is himself paying full attention to it the minds of the boys are sure to wander. Prayer and meditation are intended to teach control of the mind, but these are practised only once or twice a day. Unless the mind is controlled all day long by paying attention to everything we do, as the Master directs, we shall never gain real power over our minds, so that they may be perfect instruments. One of the most difficult parts of a teacher's duty is to turn quickly from one subject to another, as the boys come to him with their different questions and troubles. His mind must be so fully under his control that he can pay complete attention to the particular anxiety of each boy, taking up one after the other with the same care and interest, and without any impatience. If he does not pay this full attention he is sure to make mistakes in the advice which he gives, or to be unjust in his decisions, and out of such mistakes very serious troubles may arise.
