One should say to the mind, "Look here, you are my mind, you are my instrument, you are my slave and servant, you are here to help me, to work for me in this world. You have to listen to me. You will do whatever I wish, you will think whatever I wish, you will feel whatever I wish. You will not think or feel differently from my wishes, for you are my mind and you must prove in the end to be mine." By doing this we begin to analyze our mind. We begin to see where it is wrong and where it is right; what is wrong in it and what is right in it; whether it is clouded, whether it is rusted, whether it has become too cool or whether it has become over-heated. We can train it ourselves, in accordance with its condition, and it is we who are the best trainers of our mind, better than anybody else in the world.
