The word 'Iblis' refers to a figure in its own narrative; in the Iblisic narrative, the figure of Iblis is revealed as the umbra of divinity, humanity, and of nature. Iblis is the shadow of god or of the gods, the shadow of the self, and the shadow of every group of living or sentient beings, their homes or realms, and their ages, eras, or epochs; that is, Iblis is the dark side of identity, faith, and fidelity.
'Iblis,' as a term, may have begun as an epithet; the broad or manifold meaning of "to induce grief" or to wickedly "survive anguish or despair."
