I was once in the presence of a very great saint and mystic. He was a classmate of my murshid. He did many miracles and he was much revered for his great love of humanity, and he advised everybody. Someone came and said to him, "Please tell me the way to concentrate my mind. When I am in my meditation a thousand thoughts come." He said, "What thoughts, my brother?" The man said, "I have so many things to do. There is my house, my business, my office. All these thoughts come when I wish to think of God." The mystic said, you cannot give an hour to God, as if that were a business, and give the rest to your office."
