V1 AN INTRODUCTION TO SUFI DOCTRINE mine the outlook of most occidentals), discursive thought even becomes an obstacle. This it is which explains why almost every erudite European who has studied Sufism has mistaken its true position. Men of modern culture are no longer accustomed to think in terms of symbols and so modern investigations are un- able to distinguish between what, in two analogous traditional expressions, belongs to the external form and what is the essential element, and for that very reason the erudite European is led to see borrowings by one tradition from another where in fact there is only a coincidence of spiritual vision, and fundamental diver- gencies where it is only a question of differences in perspective or in mode of expression.! It is inevitable that such confusions should arise since a university train- ing and bookish knowledge are in the West deemed sufficient authority for concerning oneself with things which in the East remain naturally reserved to those who are endowed with spiritual intuition and who devote themselves to the study of these things in virtue of a true affinity under the guidance of those who are the heirs of a living tradition. In what follows an attempt will be made to show the intellectual perspective of Sufism and to this end its own way of expressing things will be adopted with the addition, where this is possible, of whatever explana- tions are needed by a European reader. At the same time analogies will be indicated between certain ideas 1. Cf. Frithjof Schuon : The Transcendent Unity of Religions, Faber, London, 1953.
