this divine darkness does not refer therefore to the lower darkness, that of the black body, the infraconsciousness (nafs ammara), but to the black Heavens, the black Light in which the ipseity of the Deus absconditus is pre-sensed by the superconsciousness.
Corbin establishes the foundational distinction: Black Light belongs to the superconsciousness and the hidden divine Essence, not to infernal or material darkness.
