PREFACE vii of Sufism and those of other traditional doctrines. To do this does not involve contradicting in any way the point of view inherent in Sufism, for Sufism has always recognised the principle according to which the Divine Revelation, transmitted by the great mediators, takes on different forms corresponding to the different aptitudes of the human groupings called on to receive them.! It is well understood that comparisons between different traditions run the risk of being misunderstood ; and for the most part Sufi masters have limited themselves to general indications of the universality of the traditions. In this they respected the faith of simple folk, for, if religious faith is a virtuality of knowledge (otherwise it would be merely opinion), its light is none the less en- closed in an emotional realm attached to one particular translation of transcendent Truth. As a result it tends to deny everything that relates to another inspired mode of expression. However, prudence in relation to the faith of a human grouping or collectivity is called for only so long as the sacred civilisation which protects that collectivity represents a more or less impenetrable “world.” Such a situation may change after an inevi- table meeting of two different sacred civilisations such as the meeting of Islam and Hinduism under the Mogul emperors, and all the more does it change when the contours of the great traditional civilisations are break- 1. This universal law of Revelation is expressed in the Quran, although only by implication : *“ The Prophet believes what his Lord revealed unto him. The faithful also believe in God and in His angels, His (revealed) books and His messengers They say : *"We make no dis*inction between the messengers of God,” ”’ (11, 284) and, again : ** We have established for every nation rites which it practices.”” (xxii, 66)
