We view Sufism not as an ideology that molds people to the right way of belief or action, but as an art or science that can exert a beneficial influence on individuals and societies, in accordance with the needs of those individuals and societies ... Sufi study and development gives one capacities one did not have before.
Idries ShahChristian scholars often say that Sufi theories are close to those of Christianity. Many Moslems maintain that they are essentially derived from Islam. The resemblance of many Sufi ideas to those of several religious and esoteric systems are sometimes taken as evidence of derivation. The Islamic interpretation is that religion is of one origin, differences being due to local or historical causes.
Idries ShahLike the bat, the Sufi is asleep to 'things of the day' - the familiar struggle for existence which the ordinary man finds all-important - and vigilant while others are asleep. In other words, he keeps awake the spiritual attention dormant in others. That 'mankind sleeps in a nightmare of unfulfillment' is a commonplace of Sufi literature
