'That is all I need tell you now,' said the Master; 'for if you obey these three rules, you will not need to know more, and if you disobey them, nothing more that I could say would help you.' 'I would have done all that without being told,' said Calladon; 'and the only thing I don't like is having nobody to see or to speak to.' 'I have taken care about that,' replied the Master, with a smile, 'and you will not be left entirely alone. When you wake up to-morrow morning, you will find a little girl beside you. She is to be your playmate and companion. She can help you to be happier and better than you have ever been before; but she can also make you worse and more miserable than if you were left by yourself. It will be according as you treat her.' 'Perhaps I had better not have her,' said Calladon. 'You must run the risk; for without risk nothing that is really good can be got,' replied the Master. 'She will not suggest either good or evil to you; but if your thoughts are good she will know it, and will help you to carry them out; and if your thoughts are evil, she will think evil too, and will give you the means of doing it.' 'Does she know all this?' Calladon asked. 'She will know nothing except from you, and as long as you are obedient to what I have told you, she will be obedient to you. But if you become disobedient, she will sooner or later begin to rule you; and whenever that happens you will be sure to suffer.' 'Then it all depends on me?' said Calladon. 'If harm comes, you will have no right to blame her,' the Master answered; 'but if good comes, you will have no right to take the credit to yourself.' 'Well,' said Calladon, after thinking awhile, 'the safest thing will be not to think of myself at all.' 'There is one thing more,' said the Master, before taking leave of him. 'You will find, hanging round Callia's neck (Callia is the name of your playmate), a little mirror, set in a frame of precious stones. This mirror will always show you an image of yourself, not as you think yourself to be, but as you really are. If you trust to what the mirror tells you, you will not know trouble; but if you disregard it, you will be in danger. The mirror is the only thing that will always tell you the truth.' 'I will always believe it,' said Calladon; and then the Master bade him good night, and Calladon fell asleep. CHAPTER III. CALLIA AND THE MIRROR. The next morning, when Calladon woke up, the first thing he saw was a lovely little girl slumbering beside him.
