A figure more legendary than that of the Mahdi, the Awaited Saviour, has not been seen in the history of mankind. The threads of the world events have woven many a fine design in human life but the pattern of the Mahdi stands high above every other pattern. He has been the vision of the visionaries in history. He has been the dream of all the dreamers of the world. For the ultimate salvation of mankind he is the Pole Star of hope on which the gaze of humanity is fixed.
