There are three important things to be considered in the development of insight. The steady gaze of the eyes and of the mind, which helps one in penetration. Another thing is losing everything else from one's sight except the object through which one wishes to penetrate. And that comes by sufficient interest in penetration. But the third thing, which helps most is losing for the moment the thought of one's self. When one's body and mind are not before one, it is then that one has the proper insight into things one wishes to know and understand. Sufis therefore have different concentrations by which they are helped not only in keeping their gaze steady, but standing firm upon one thought. When a person cannot take interest in any object or being, then his mind is not steady, for there is nothing that it takes interest in. It is the interest which makes the mind steady. A certain thought which is inspiring or helpful in some way, or a certain form which is inspiring when once one has concentrated upon it. Then the mind becomes steady also, then it can easily hold an object before it without wavering.
