The object of worship of the Sufi is beauty. Not only beauty in form and color and line, but beauty in all its aspects, from gross to fine. The moral for the Sufi is the understanding of harmony: in what way one can harmonize with one's soul and how one can harmonize with one's fellow human being. Instead of labeling one action as a sin and another action as a virtue, instead of arguing on the subject of the right and wrong of certain actions, the Sufi trains him or herself, as a musician trains his or her ear, to see what is harmonious and what lacks harmony in oneself and in one's dealings with others.
