The Sufi recognizes both these aspects in himself, the imperfect and mortal aspect of his being and the Perfect, the Immortal, Aspect of his Being. The former his outer self represents; the latter is his innermost self. Since the imperfect self covers his soul and confines it in a limited being, he recognizes at the same time the greatness of the Perfect Being, and calls himself "I," a servant of God, and God the Lord of the whole existence. In the Sufi schools in the East this idea is expressed in a Qur'anic allegory which moves those who enjoy its poetic delicacy. In the Qur'an it is related that, when the first man was made, he was asked: "Say, who is thy Master?" and he answered, "Thou art my Lord."
