At the beginning of this century, in the heart of Africa, in Mali, the light of God shone on a man: Tierno Bokar, who was called the Sage of Bandiagara.
Sheikh of the Tidjaniya Sufi brotherhood, Tierno Bokar was a pure and high figure not only of Islam in black Africa, but of universal spirituality. His life is traced first in its places and in its political and religious context to situate the word and teaching of the Master, which are the subject of the other two parts of the work.
