"The Active Imagination perceives and shows to itself an Earth which is other than that Earth which is seen in ordinary sense experience... The Image of the Earth is revealed in the form of an Angel... In this sense, the categories of the sacredness which possess the soul can be recognized in the landscape with which it surrounds itself and in which it shapes its habitat, whether by projecting the vision on an ideal iconography, or by attempting to inscribe and reproduce a model of the vision on the actual earthly ground." - Henry Corbin, Spiritual Body & Celestial Earth, 29-30.Louis Massignon writes, "The art of Persian miniatures, without atmosphere, without perspective, without shadows and without modelling, in the metallic splendor if its polychromy, peculiar to itself, bears witness to the fact that its orginators were undertaking a kind of alchemic sublimation of the particles of divine light imprisoned in the 'mass' of the picture. Precious metals, gold and silver, come to the surface of the fringes and the crowns, of the offerings and cups, to escape from the matrix of the colors."
Corbin says, "Let us make no mistake as the meaning of these colors... when we find them again in the gold background of the Byzantine icons and mosaics... it remains always a question of the same transfiguring light..." - The Man of Light in Iranian Sufism, 137-8.
