It is also told that a Sufi had a pupil who said to him, "Teacher, I cannot concentrate on one thing. If I try to concentrate on one object, other objects appear; then they become so muddled that I do not know which is which. It is difficult to hold the mind on one object." The teacher said, "Your difficulty is your anxiety. The moment you begin to concentrate, you are anxious that your mind might wander away. If you were not anxious about it, your mind would have poise; your anxiety makes it more active. If you just take what it gives you, instead of looking behind it in order to see where it goes, if you change this tendency and meet the mind face to face, seeing how it comes to you and with what it comes, you will be able to concentrate better."
