Light occupies a position of singular density in the depth-psychology corpus, functioning simultaneously as a cosmological principle, a psychological metaphor, an alchemical agent, and a mystical phenomenon of inner experience. The tradition does not treat light as a simple opposed term to darkness; rather, the most searching voices — Corbin, Jung, Hillman, Plotinus — insist on its paradoxical character. Corbin's exhaustive mapping of Iranian Sufi visionary experience traces an entire spectrum from colored photisms through to the supreme 'black light' of divine ipseity, arguing that light here is never merely physical but constitutes the very substance of the spiritual person, the 'man of light.' Jung and his interpreters recover the lumen naturae of Paracelsus, a light hidden within matter and nature that is distinct from the light of revelation, and locate in alchemical tradition the motif of a 'light surpassing all lights' latent in the lapis. Hillman complicates triumphalist narratives by insisting that every act of conscious illumination simultaneously darkens, so that light and darkness are co-created rather than sequentially evolved. Plotinus and Aristotle supply the metaphysical substrate: light as activity, as the actualization of transparency, as the medium by which intellect cognizes itself. Ficino and the I Ching add cosmological dimensions — solar intelligence and the cosmic principle of brightness clinging to bodies. Together these sources make light one of the most polysemous and theoretically loaded terms in the entire library.
We therefore need a metaphysics of Light whose paths will be mapped by the mystic's spiritual experience of colors, especially, in the present case, the experience of the Iranian Sufis.
Corbin argues that a full metaphysics of light must be grounded in the visionary chromatic experience of the Iranian Sufi masters, distinguishing between divine 'black light' and the darkness of matter.
, The Man of Light in Iranian Sufism, 1971thesis
The world of colors in the pure state, that is, the orbs of light, is the totality of the acts of this Light which makes them lights and cannot itself be manifested except by these acts, without ever being itself visible.
Corbin articulates the Sufi doctrine that absolute Light is self-concealing, knowable only through its theophanic acts in the soul of the mystic.
, The Man of Light in Iranian Sufism, 1971thesis
black is the color of the pure divine Ipseity in Itself, in the same way that to Najm Razi this color applied only to the attributes of inaccessible Majesty, to the Deus absconditus.
Corbin presents the doctrine of black light as the ultimate inversion of ordinary luminosity, identifying pure darkness with the hidden divine self beyond all manifestation.
, The Man of Light in Iranian Sufism, 1971thesis
For every bit of light that we grasp out of archetypal ambivalence, illumining with the candle of our ego a bright circle of awareness, we also darken the remainder of the room.
Hillman argues that consciousness and unconsciousness are co-created simultaneously, so that lighting one region necessarily darkens another, rejecting any simple evolutionary narrative of light triumphing over darkness.

Man at his birth is 'endowed with the perfect light of nature,' Paracelsus calls it 'primum ac optimum thesaurum, quem naturae Monarchia in se claudit'
Jung recovers the Paracelsian concept of the lumen naturae as an innate psychic light given to the inner body, identifying it with the world-wide symbolism of the hidden treasure.
, The Structure and Dynamics of the Psyche, 1960thesis
My light excels all other lights, and my goods are higher than all other goods. I beget the light, but the darkness too is of my nature.
Jung cites the alchemical Mercurius to demonstrate that the light of nature in alchemy is paradoxically inseparable from darkness, making light a figure of coincidentia oppositorum.
, Alchemical Studies, 1967thesis
our vision is light or rather becomes one with light, and it sees light for it sees colours. In the intellectual, the vision sees not through some medium but by and through itself alone.
Plotinus argues that in intellectual vision, light is not a medium but the identity of seer and seen, the Intellectual-Principle knowing itself as light.
, The Six Enneads, 270thesis
it is from him that there issues the 'light surpassing all lights,' the lux moderna, for the lapis is none other than the figure of light veiled in matter.
Jung identifies the alchemical lapis with a supreme light hidden within matter, linking Mercurius to the archetype of the unconscious as a latent luminosity.
, Collected Works Volume 3: The Psychogenesis of Mental Disease, 1907thesis
Mercurius is an adumbration of the primordial light-bringer, who is never himself the light, but a φωσφόρος who brings the light of nature, the light of the moon and the stars which fades before the new morning light.
Jung distinguishes Mercurius as light-bearer from light itself, elaborating a hierarchy in which the lumen naturae precedes but yields to the higher light of self-knowledge.

The perception of the colored photisms coincides with the moment when these suprasensory senses come into action as the organs of the man of light, of the 'particle of the divine light.'
Corbin maps the colored photisms of Sufi experience onto the activation of suprasensory organs, identifying their appearance with the emergence of the spiritual person constituted by divine light.
, The Man of Light in Iranian Sufism, 1971supporting
The colored photisms which Najm Razi proceeds to describe rise step by step from the moment when the spiritual individuality is triumphantly freed from the lower ego and, on reaching the degree of consciousness, makes its way to the degree of the pacified soul.
Corbin traces the progression of colored lights in Sufi practice as stages of spiritual liberation, each photism corresponding to a degree of inner transformation.

The motive power to fuel this effort is the light itself, that is, the particle of light, the 'man of light,' effecting the conversion of like to like.
Corbin presents the 'particle of light' within the human being as the active agent of spiritual transformation, operating by the Neoplatonic principle of like attracted to like.

In this pure luminescence we recognize one Iranian representation above all others: the Xvarnah, the light-of-glory which, from their first beginning, the beams of light establish in their being, of which it is at once the glory and the destiny.
Corbin identifies the Iranian concept of Xvarnah — the light-of-glory — as the fundamental archetype unifying personal destiny and divine radiance in Sufi and Mazdean traditions.

The knowledge arising with this first light finally and inevitably becomes the scientia hominis, the knowledge of man, who asks himself: 'Who is it that knows and understands everything? Why, it is myself.'
Von Franz traces Augustine's and Eckhart's distinction between morning and evening knowledge, showing how the 'first light' of creation becomes the self-referential light of ego-consciousness that must return to God.

if it is a quality, some quality of some substance, then light, equally with other qualities, will need a body in which to lodge: if, on the contrary, it is an activity rising from something else, we can surely conceive it existing, though there be no neighbouring body.
Plotinus poses the foundational metaphysical question of whether light is substance or activity, concluding for the latter and thereby enabling its use as a model for immaterial emanation.

light is the activity of this thing, of the transparent as transparent. And wherever this is there is potentially also darkness. But light is as the colour of the transparent, when it is rendered transparent in actuality.
Aristotle defines light as the actualization of the transparent medium, establishing a philosophical precedent for treating light as act rather than substance.

Hence our first task is to explain what light is. Now there clearly is something which is transparent, and by 'transparent' I mean what is visible, and yet not visible in itself.
Aristotle sets up his analysis of vision by distinguishing the transparent medium from light itself, founding the epistemological question of light's nature as primary to any theory of perception.
