The religions, the mystics, the philosophers of all ages have given the key to this secret, and that is what the Sufi message is bringing back to humanity. Christ has said it so beautifully: "Be ye perfect as your Father in heaven is perfect." The yearning of every soul is for the realization of that perfection; that is the longing, consciously or unconsciously, of every thing, of every being in this world. There is something in the whole creation which is like an alarm-clock set for a certain time to make a sound, so that one may awaken. That clock sounds through all the activity of evolution, and when a certain point of evolution is touched man is awakened by the alarm: that is the word that was lost. It has its echo in the longing.
