The work of a mystic, therefore, is to study life. To the mystic life is not a stage-play or an entertainment. For the mystic it is a school in which to learn, every moment of one's life; it is a continual study. And the scripture of the mystic is human nature; every morning he turns a new page of this scripture. And the books of the great ones who have brought the Message to the world from time to time, and which became sacred scriptures and were read for thousands of years, generations of people taking their spiritual food from them, are the interpretations that they gave of this scripture which is human nature. That is why all the sacred scriptures always have the same sacred feeling.
