Continuing, he assumes a peculiar theory of light, which betrays a really Persian origin. One special light he designates by the old Persian word "Isfahbad." The Godhead Itself he calls the "light of lights." In other places he borrows from Neo-Platonism. He assumes a region in the heavenly spheres where the ideal prototypes of existing things are found. The saints and devout ascetics, according to him, have the power to call those ideal prototypes into real existence, and these can produce at their wish, food, figures or melodies, etc. Suhrawardy's optimistic way of conceiving the world is peculiar for a Moslem. While Islam regards the world as a vale of tears, and earthly life as a time of temptation, he finds the evil in this world much less than the good. The following sentences of his work are noteworthy: "Know that souls in whom the heavenly illuminations are lasting, reduce the material world to obedience. Their supplication is heard in the Upper World, and fate has already decreed that the supplication of such a person for such an object should be heard. The light which streams from the highest world is the Elixir of power and knowledge and the world obeys it. In the purified souls is reproduced a reflex of God's light, and a creative ray is focussed in them. The 'evil eye' is only a light-power, which influences objects and injures them." Soon after Suhrawardy had been put to death, nearly the whole of his books were committed to the flames by order to the Caliph Nasir. [54] From Von Kremer. CHAPTER XIV JALALUDDIN RUMI Jalaluddin Rumi has been called by Professor Ethe (in the _Encyclopaedia Britannica_) "the greatest pantheistic writer of all ages." However that may be, he is certainly the greatest mystical poet of Persia, though not so well known in Europe as Saadi, Hafiz and Omar Khayyam. Saadi, Jalaluddin's contemporary, seems to have been conscious of this, for when asked by the Prince of Shiraz to send him the finest poem which had been published in Persia, he sent an ode from Jalaluddin's "Diwan."
