The phrase of the "Eternal Ferment" and its relation to "the Khosravani wisdom" in the Illumination wisdom has been an excuse for some scholars such as Henry Corbin to regard the main purpose of this wisdom as reviving the Iranian ancient wisdom which known as the wisdom of Khosravani. There is much evidence in the Illumination wisdom that shows Suhrawardi's work is the foundation of a new wisdom, not merely the revival of an existing tradition. The conceptual analysis of the "Eternal Ferment" and its peripheral concepts, and the consideration of the instances of the Eternal Ferment in the heart of different civilizations, reveal the truth of Sheikh Eshraq's view contrary to these claims. There are many differences between the word "Established" and "resurrected"; the resurrection is secondary, subordinate, and imitative, but the establishment is a genuine, fundamental, and innovative one that can also lead to the resurrection. "Resurrect" is consistent with the influence of the historical line while the Eternal is not the historical but beyond the historical, and receiving from the Eternal Ferment means receiving from a source beyond the historical truth. Therefore, the relationship between Iranian ancient wisdom and the Suhrawardi's illumination wisdom cannot be the innately aim of Suhrawardi's philosophical activity. If sheikh Eshraq considers Khosravi's wisdom to be a manifestation of the Eternal Ferment, so is his view of Pythagorean wisdom that emerged from the Eternal Ferment, as well as other wisdoms in civilizations such as India and Babylon. Proponents of the claim to revive Iranian wisdom must therefore repeat the same thing about the revival of Greek wisdom and other wisdoms. Thus, the main purpose of Suhrawardi, contrary to scholars claim, is to establish Illumination wisdom, not to revive Khosravi's wisdom.
