I was at a reception at a friend's house and someone was there who disputed with everybody, so that all were tired. I avoided him, but my friend put me forward to speak with him, so I had to go and meet him. When he heard that I was a speaker and a teacher of philosophy he thought, "This is the person I want", and said, "I do not believe in God." As it is the work of the Sufi to harmonize, to unite, I said, "Do you not? But you believe in this manifestation and in the beauty of this world of variety, and that there is some power behind it which produces it." He said, "I believe all that, but I do not call it God." I said to him, "You believe that every effect has a cause, and that for all these causes there must be an original cause. You call it cause, I call it God; it is the same." "I believe in that", he said, "but why should I worship this personality, why should I call it God?"
