Bab'Aziz: The Prince That Contemplated His Soul

As others have said, this movie can qualify as a "best movie of my life". The person that commented about the movie not focusing exclusively on the pure/ascetic aspects of Sufi has a valid point, but it is on purpose that this is the case.

I strongly recommend watching the other two movies of the "dessert trilogy" where the very same path towards illumination, is seen from the outside (first movie), then from the point of view of the one drawn into joining in (second movie) and with Bab'aziz comes the end of the cycle.

Behind the movie and the trilogy itself, the Director (Nacer Khemir) is of course the conduit that guides to the viewers the source of the light. To dedicate all your artistic career to a single trilogy over so many years, puts Mr. Khemir in the line of the Muslim craftsmen that adorned so beautifully the buildings we see throughout the movies... He succeeded in turning a medium (cinematography) mostly used by anti-traditional messages in a veritable page of a scripture. The movie is able to lead people to "search more" and provides them a valid direction as well.

Some of Nacer's interviews one can find on the net are worth watching too...
