A student and his teacher were walking through the forest．The student was1  by the fact that his mind was in constant（不断的） unrest．

He asked his teacher 2 , “Why most people’s minds are restless , and only a few possess a 3  mind? What can one do to4   the mind?”

The teacher looked at the student, smiled and said, “I will tell you a story．An elephant was 5  and picking leaves from a tree．A small fly came, flying and buzzing near his 6  ．The elephant waved it away with his big ears, Then the fly came again, and the elephant 7  it away once more．

This was 8  several times．Then the elephant asked the fly, “Why are you so restless and 9 ？Why can’t you stay for a while in one place? ”

The fly answered, “I am10 to whatever I see, hear or smell．My five senses pull me constantly in all 11  and I cannot resist them．What is your 12 ? How can you stay so calm and still?”

The elephant stopped 13  and said, “My five senses do not rule my attention．Now that I am 14  immersed（沉浸） in eating ．In this way I can enjoy my 15  and chew it better．I rule and control my attention, and not the other way around．”

Upon 16  these words, the student’s eyes opened wide and a 17  smile appeared on his face．He looked at his teacher and said, “I understand! If my five senses are in control of my 18 , then my mind will be in constant unrest．If I 19  my five senses and attention, then my mind will become calm．”

“Yes, that’s right,” answered the teacher,” If the mind is 20  , it will go wherever the attention is．Control your attention, and you control your mind．”
