The aim of the Sufi, therefore, is to see and yet not be interested. Suppose you were climbing Mount Everest, and were interested in a certain place which you liked, to admire it, or in the part which you disliked, to break it. In both cases you have allowed your feet to be chained to that place for more or less time, and by that have lost time and opportunity; whereas you could have gone on forever and perhaps seen and learnt more than by stopping there. Those who trouble about others' thoughts and interest themselves in others' actions most often lose their time and blunt their inner sight.
