At the beginning of the tale that Sohravardi entitles "The Crimson Archangel," the captive, who has just escaped the surveillance of his jailers, that is, has temporarily left the world of sensory experience, finds himself in the desert in the presence of a being whom he asks, since he sees in him all the charms of adolescence, "O Youth! where do you come from?" He receives this reply: "What? I am the first-born of the children of the Creator [in gnostic terms, the Protoktistos, the First-Created] and you call me a youth?" There, in this origin, is the mystery of the crimson color that clothes his appearance: that of a being of pure Light whose splendor the sensory world reduces to the crimson of twilight. "I come from beyond the mountain of Qaf... It is there that you were yourself at the beginning, and it is there that you will return when you are finally rid of your bonds."
