Your child will give you great joy through its play and prattle, but when it interferes with your work or demands your attention when you are working on something important, you get very angry with it. Your child now becomes your source of joy as well as grief! Remember, there is nothing in the world which can give you unmixed joy. Even if there is one such thing, when it is lost, you will become very sad! This is in the very nature of this world. So try to correct the very source of joy and sorrow, the mind. Control your mind and train it to accept and see the real nature of this objective world, which attracts and repels you in turns. This is the real fruit of education!
