Scholars of the East and West have heroically consecrated their whole working lives to making available, by means of their own disciplines, Sufi literary and philosophical material to the world at large. In many cases they have faithfully recorded the Sufis' own reiteration that the Way of the Sufis cannot be understood by means of the intellect or by ordinary book learning.
Idries Shah... when we are talking about 'Christians' and 'Moslems' we must first make sure that we are talking about people who have an idea, which should be more or less correct, as to what the other is supposed to believe and what he is expected to do as a consequence of that belief.
