 This vertical hierarchy of lights mirrors the Avicennan Neoplatonic process of emanation of intellects. Suhrawardi, however, increases the number of active principles (the Peripatetics immaterial intellects, something Averroes denounced in Avicenna’s Neoplatonic ontology). Each of level of immaterial dominating lights is associated with a celestial sphere. They are no longer limited to al-Farabi’s (d.950) nine spheres or to those and their “varying number of subordinate spherical bodies” Avicenna suggested with his “second kinematic model” (Janos 2011, 172–9). This development may have inspired Suhrawardi’s indefinite, though not infinite, number of immaterial dominating (qahira) lights that are more “than ten, or twenty, or one hundred, or […], or a hundred thousand”, lights that are, in fact, as numerous as the stars in the fixed heavens (PI, §151; Arslan 2014, 138–9).
