The greatest progress is a constant expansion of the divine spirit, expansion in any direction so long as the ideal of unity is applied; this is the ideal of the Sufis. It is not the desire of the Sufis that all should become members of the Sufi Movement; but the ideal of its members is to invite humans to become members of humanity. Sufism is not a new religion or community; it does not want to add a community to the world. It is an attitude of life, not taught by any particular principle or dogma; it is to tune oneself to a certain pitch, so that the heart can become tuned to the Lord. This is the only religion that exists; this is the only message that Christ gave.
