(Kalam) is speech or words. The Source, Allah, is the Great Silence. In the process of descent, the Supreme Silence is firstly qualified with letters which then appear as words. The words become a sentence or sign which then appears as a form or book. The world is a book and the human is a book. In these two books we can read the signs of Allah, "on the horizons and within ourselves", which will enable us to ascend, and dwell once again, in the Great Silence.
