The Sufi understands that although God is the source of all knowledge, inspiration, and guidance, yet man is the medium through which God chooses to impart His knowledge to the world. He imparts it through one who is a man in the eyes of the world, but God in his consciousness. It is the mature soul that draws blessings from the heavens, and God speaks through that soul. Although the tongue of God is busy speaking through all things, yet in order to speak to the deaf ears of many among us, it is necessary for Him to speak through the lips of man. He has done this all through the history of man, every great teacher of the past having been this Guiding Spirit living the life of God in human guise. In other words, their human guise consists of various coats worn by the same person, who appeared to be different in each. Shiva, Buddha, Rama, Krishna on the one side, Abraham, Moses, Jesus, Muhammad on the other; and many more, known or unknown to history, always one and the same person. Those who saw the person and knew Him recognized Him in whatever form or guise; those who could only see the coat went astray. To the Sufi therefore there is only one Teacher, however differently He may be named at different periods of history, and He comes constantly to awaken humanity from the slumber of this life of illusion, and to guide man onwards towards divine perfection. As the Sufi progresses in this view he recognizes his Master, not only in the holy ones, but in the wise, in the foolish, in the saint and in the sinner, and has never allowed the Master who is One alone, and the only One who can be and who ever will be, to disappear from his sight. The Persian word for Master is Murshid. The Sufi recognizes the Murshid in all beings of the world, and is ready to learn from young and old, educated and uneducated, rich and poor, without questioning from whom he learns. Then he begins to see the light of Risalat, the torch of truth which shines before him in every being and thing in the universe, thus he sees Rasul, his Divine Message Bearer, a living identity before him. Thus the Sufi sees the vision of God, the worshipped deity, in His immanence, manifest in nature, and life now becomes for him a perfect revelation both within and without.
