Around the commentary of a verse from the Koran says "light" illuminating Ghazali offers three chapters:
- Chapter 1, the word exegesis "light" is a pretext for the analysis of its intelligibility: the appearance and the five external senses, external observers of the intellect [in the internal servants have imagination, the estimated capacity, the cognitive faculty, the recall ability and memory] itself can afford to set sail on the Face of God at the cost of a personal inner experience of "setting off" of it -C needed to identify Him;
- Chapter 2, the symbolic representation of elements are specified then the different faculties of man identified above are included in this light. The chapter concludes with an explanation of the different components of the verse "called the light" whose meaning (s) will light (s) then;
- Chapter 3, Ghazali outlines barriers to disclosure for the individual to achieve full self-realization (Sufi) and then proves a shrewd connoisseur of human mentality and psychology.
In the end, a lot of wisdom in a few pages away from the finiteness and sadness of contemporary materialism.
