We're trained to sort everything into two bins: things that are physically real (rocks, bodies, the chair you're sitting on) and things that are just in your head (dreams, fantasies, the unicorn you're picturing now). One is out there and solid; the other is inside and made of nothing. The Iranian mystics said this two-bin sorting is a catastrophic mistake that has crippled our understanding of reality, because there is a third kind of place — and it's the one that matters most.
They called it Hūrqalyā, or the 'ālam al-mithāl — the imaginal world. It is a genuine universe "having extent but different from the sensory world — a universe with infinite wonders."1 It has geography, cities, light, dimension — it's not nothing, not "just imagination" in the dismissive sense. But it's not made of matter either. It's the realm where the spiritual takes on form and the formal becomes spiritual: where visions are objective realities you travel to, not subjective pictures you invent. Sohravardī insisted on this with total seriousness: the imaginal world is "a concrete spiritual universe, not a philosophical or conceptual world."2 When a mystic has a true vision, he hasn't made something up — he's gone somewhere.
Source trust note. From Billinge's War Yoga: Zurxāne (Sanctus Europa Press, an identitarian publisher). Hūrqalyā and the mundus imaginalis are central to Iranian Shaykhī and Illuminationist metaphysics; the concept's great modern expositor is Henry Corbin, who coined "imaginal" (vs. "imaginary") to translate it, and whom Billinge follows. The doctrine, the eighth-clime location, the barzakh-barrier, and the Emerald Cities are all genuine. The "WarYogin passes the vara of Yima" militant overlay is excluded; the imaginal-world ontology is kept.
Hūrqalyā is the eighth clime — the "lost continent," the interworld that sits, in Avicenna's nine-sphere scheme, between the seventh (the highest natural heaven) and the ninth (the divine Throne). It is "the 'interworld' between the lower spheres and the highest," and it "is said to contain other universes within: boundless states of consciousness."3
Its defining structural property is that it's a barzakh — a "barrier" or threshold realm. "This eighth sphere is the barzakh ('barrier'). It is the treacherous interworld between lower and higher ones. This is considered a dangerous state to cross, as the fall is profoundly deep for those who lose their way."4 A barzakh is precisely an in-between — the place where two orders of reality meet and interpenetrate. Hūrqalyā is where the material world and the spiritual world overlap, the membrane between them, which is exactly why it's both the gateway to the higher realms and the most dangerous place to get lost.
Its location is the summit of the Cosmic Mountain: "The eighth kešvar — the mystical Earth of Hūrqalyā with its Emerald Cities — is on the summit of the Cosmic Mountain Harā Bārāzaitī, called Qāf in the Islamic tradition."5 And its orientation is vertical, not horizontal. Corbin is emphatic: "The direction in which we must seek this 'eighth clime' is not on the horizontal but on the vertical. This suprasensory, mystical Orient... is at the heavenly pole."6 You don't reach Hūrqalyā by travelling across the world (it's not a hidden country on the map); you reach it by ascending through the levels of being to the pole.
The genius of the imaginal — and Corbin's central contribution — is the claim that imagination is a faculty of perception, not just of invention. In the two-bin worldview, imagination is the thing that makes up — it produces the unreal, the fantasy, the merely-mental. The imaginal doctrine says: that's one function of imagination (the degraded one, what Corbin calls the merely "imaginary"), but imagination has a higher function — it's the organ by which you perceive the imaginal world, the way the eye perceives the sensory one. The active imagination (as opposed to fantasy) is a sense, and Hūrqalyā is what it senses.
This solves a problem that otherwise makes mysticism incoherent. When a mystic reports seeing the Emerald Cities, or his Perfect Nature, or the coloured lights of the ascent — is he perceiving something real or hallucinating? The two-bin worldview forces a brutal choice: either these are physical (clearly false — no telescope finds the Emerald Cities) or they're "just imagination" (i.e., meaningless fantasy). The imaginal doctrine refuses the choice. The visions are real perceptions of a real world — the imaginal world — perceived by the appropriate organ (the active imagination), exactly as the chair is a real perception of the physical world perceived by the eye. The mystic is neither lying nor deluded; he's reporting from somewhere, using the faculty fitted to that somewhere.
And this is why the realm has its characteristic two-way traffic: "what is corporeal becomes spirit and what is Spiritual assumes a body." Hūrqalyā is where the spiritual gets a form (so it can be perceived) and where the material gets spiritualized (so it can ascend). It's the transformer between the two orders — the place where pure spirit, which has no shape, can take on the shape that lets a soul encounter it, and where the embodied soul, which is stuck in matter, can shed enough density to rise. The whole ascent requires this middle realm, because without it there'd be no bridge between the body you start in and the pure Light you're climbing toward — you can't jump from matter to spirit directly; you cross through the imaginal, where they meet.
Hūrqalyā is the ontological keystone of the Iranian-mystical material — it's the realm everything visionary happens in:
For the Indic limb, the imaginal world is the structural cousin of the subtle realm (sūkṣma loka / the realm of the taijasa dream-self) — a genuine plane of reality, between gross matter and pure consciousness, where the subtle body operates and visions are objective. The vault's recurring distinction between the gross, subtle, and causal bodies maps onto the sensory / imaginal / intelligible triad: the imaginal world is the subtle plane, and the active imagination is the subtle body's organ of perception.
Billinge preserves a hauntingly strange detail: the Emerald Cities of Hūrqalyā are "populated by a marvellous angelic race... who are unaware of the earthly Adam or of Iblis (Ahriman)." Like the vara of Yima, "these cities secrete their own Light, needing none externally. They are illuminated by their own Light: an Inner Light."8
Sit with what it means that the inhabitants don't know about Adam or the Devil. The earthly Adam is the start of our story — the fall into matter, mortality, the knowledge of good and evil. Iblis/Ahriman is the principle of evil that fall let into the world. To be "unaware of Adam or Iblis" is to belong to a world that the fall never happened in — a realm untouched by the descent into duality, where the original unfallen condition simply continues. The Emerald Cities are what reality looks like where the catastrophe didn't occur. They don't need external light because they were never plunged into the darkness that makes external light necessary; they kept the inner light the fall extinguished for us.
This is why the parallel to Yima's vara is exact and not decorative. Yima's vara is the sheltered remnant of the Golden Age, lit by its own light, preserved through the cosmic winter — a pocket of the unfallen world kept intact underground. The Emerald Cities are the same thing on the vertical axis: a pocket of the unfallen world kept intact at the pole. The case reveals what Hūrqalyā actually is, beneath the geography: it's the persistence of the unfallen — the part of reality where the original luminous condition never stopped, which the seeker is climbing back toward. To reach the imaginal world is to return to the world-before-the-fall, still shining its own light, still ignorant of the darkness that swallowed the rest. The ascent isn't to a new paradise; it's to the old one that was never lost — only hidden, at the pole, secreting its inner light, waiting.
You have an inner life that produces images — in meditation, in dreams, in the hypnagogic edge of sleep, in the work of active imagination. The two-bin worldview has trained you to dismiss all of it as "just imagination," meaningless by definition. The imaginal doctrine hands you a different, riskier, more fertile stance — and a discipline for not being destroyed by it.
You begin by granting the images the possibility of being perceptions rather than fabrications — by treating the active imagination as a sense that might be reporting from somewhere real, not just a fantasy-engine. You stop asking "did I make this up?" (the two-bin question, which forces you to either inflate the vision into physical fact or deflate it into nothing) and start asking "what is this showing me, and from where?" You engage the images as encounters — you let the figures act, speak, surprise you (a genuine perception surprises; pure fantasy only flatters), and you treat the surprise as evidence you're perceiving rather than inventing.
But — and this is the whole discipline — you remember that Hūrqalyā is a barzakh, "a dangerous state to cross, where the fall is profoundly deep." The imaginal world is exactly where genuine perception and ego-projection look identical, where the most convincing visions are precisely the most dangerous, where seekers "lose their way" and fall. So you hold every image lightly and you keep an anchor in the sensory and ethical world below: you don't quit your daily obligations to live in the visions, you don't believe the flattering ones, you don't act on a vision the way you'd act on a physical fact, and you keep a guide or a tradition to check your perceptions against. The mature practice is to take the imaginal seriously without taking it literally — to honor the images as real perceptions of a real realm while never forgetting that this particular realm is the one where you're most likely to mistake your own face for an angel's. Travel the imaginal; don't get lost in it.
Hūrqalyā has two opposite failure modes, and they're the two bins it was invented to escape — which means losing the imaginal world happens by sliding into either of the errors it sits between.
Literalizing is mistaking the imaginal for the physical — believing the Emerald Cities are a hidden country you could reach by boat, the visions are material events, the angelic encounters are sensory facts. The diagnostic sign is the seeker who looks for the spiritual world on the horizontal (a lost continent, a physical location) rather than on the vertical — Corbin's exact warning. This collapses the imaginal down into the sensory bin, and it produces literalist madness: the man who thinks he can physically photograph the Throne.
Dismissing is the opposite collapse — mistaking the imaginal for the merely imaginary, "just in your head," meaningless fantasy. The diagnostic sign is the modern reflex that hears "imaginal world" and translates it instantly to "make-believe." This collapses the imaginal up into the abstract/unreal bin, and it produces the disenchanted flatland where every vision is pathology and the entire mystical tradition is dismissed as people reporting their hallucinations earnestly.
The imaginal world only exists in the refusal of both collapses — it is, by definition, the realm that is neither physical nor unreal, and it vanishes the instant you let it fall into either bin. This is why Corbin had to coin a new word ("imaginal," to block the slide into "imaginary"): the concept has no stable home in a two-bin language, and keeping it alive requires actively resisting the gravitational pull of both errors at once. Most of what looks like disagreement about mysticism is really just one camp literalizing and the other dismissing — both having already lost the third realm the whole thing was about.
Billinge follows Corbin entirely, and the convergence is the scholarly mainstream: Corbin's mundus imaginalis is one of the most influential concepts in 20th-century religious studies, and Billinge transmits it faithfully. The genuine tensions are interpretive. First, how literal is the realm: Corbin walks a careful line (the imaginal is "objective" but not "physical"), and readers persistently collapse it one way or the other — the doctrine is notoriously hard to hold without sliding into either literalism or dismissal, and even sympathetic scholars debate exactly what ontological status Corbin meant to grant it. Second, the cross-traditional reach: Billinge (with Corbin) maps the imaginal onto the Indic subtle realm, and the parallel is strong, but whether these are the same metaphysical claim or two analogous ones is the recurring Perennialist question the vault keeps flagging. The convergence is the concept (a real third realm, perceived by active imagination); the tension is its precise ontological weight, which the tradition itself holds with deliberate, perhaps necessary, vagueness.
Plainly: the claim that there's a real realm that is neither physical nor merely mental, perceived by an imagination that is a sense rather than a fantasy-engine, is a structure psychology and creative practice both desperately need and usually lack.
The Sharpest Implication. Most of reality has been amputated by a two-bin worldview that recognizes only the physical and the unreal — and the realm it amputated, the imaginal, is the one where everything that matters spiritually actually happens. We've trained ourselves to perceive with the wrong instrument: treating imagination as a fantasy-engine when it's also a sense-organ, and so dismissing as "made up" the very perceptions of the third realm we most needed. The whole mystical tradition is, from this angle, an attempt to keep a faculty of perception alive that the modern world declared was only good for lying.
