There is one thing in this world that you must never forget to do. If you forget everything else and not this, there is nothing to worry about; but if you remember everything else and forget this, then you will have done nothing in your life. It is as if a King has sent you to some country to do a task, and you perform a hundred other services, but not the one He sent you to do. So human beings come to this world to do particular work. That work is the purpose, and each is specific to the person. If you do not do it, it is as though a priceless Indian sword were used to slice rotten meat. It is a golden bowl being used to cook turnips, when one filing from the bowl could buy a hundred suitable bowls. It is a knife of the finest tempering nailed into a wall to hang things on.
