Muḥyī al-Dīn Ibn ʿArabī (1165–1240) is the supreme metaphysician of Islamic mysticism — perhaps of any mysticism. Born in Murcia in Andalusia, he traversed the Islamic world from Spain to Mecca to Anatolia, producing a corpus of over 300 works. His central doctrine, Waḥdat al-Wujūd — the Unity of Being — is among the most precise cartographies of non-dual reality ever drawn: there is only one Being, and everything that appears to exist is that Being knowing itself through its own Names.

"My heart has become capable of every form:
it is a pasture for gazelles and a convent for Christian monks,
a temple for idols and the pilgrim's Kaaba,
the tables of the Torah and the book of the Quran.
I follow the religion of Love."
— Ibn ʿArabī, Tarjumān al-Ashwāq (Interpreter of Desires)

Waḥdat al-Wujūd — The Unity of Being

The phrase Waḥdat al-Wujūd does not appear in Ibn Arabi's own writing — it was coined by his followers to name his position. What Ibn Arabi actually says is more subtle: wujūd (Being, existence) belongs, strictly speaking, only to God — the Real (al-Ḥaqq). Everything else has a kind of borrowed, relative existence that it receives from the Real. The world is not God; but neither is the world truly separate from God. It is the self-disclosure (tajallī) of the Real through its own Names and Attributes.

This is not pantheism — Ibn Arabi insists that God is not exhausted by the world. The infinite Real transcends its own manifestations. He uses the formula: God is both tanzīh (incomparable, transcendent) and tashbīh (comparable, immanent). To absolutize only transcendence is to miss the self-disclosure; to absolutize only immanence is to confuse the mirror with the face. The Great Master holds both poles simultaneously — which is exactly what the tree of Kabbalah holds in the relationship between Ain Soph and the Sefirot.

The engine of creation in Ibn Arabi's system is the "breath of the Compassionate" (nafas al-Raḥmān) — an exhalation through which the latent divine possibilities (aʿyān thābita, "fixed entities" or divine archetypes) receive existence. These archetypes exist first in God's knowledge, then are breathed into being. The world is, in this sense, God dreaming itself into multiplicity — not to lose itself, but to know itself: "I was a Hidden Treasure, and I loved to be known, so I created the world."

The Three Registers of Self-Disclosure (Tajallī)

I
Al-Dhāt — The Essence
The Absolute · The Hidden Treasure · Beyond all names
The Real in its utter unknowability — prior to any name, attribute, or distinction. Not "God" as a concept but wujūd itself, pure Being-without-qualification. Corresponds to Kabbalistic Ain Soph before the first Sefirah, and to Plotinus's The One before the emanation of Nous.
II
Al-Ṣifāt — The Names and Attributes
Asmāʾ wa-Ṣifāt · The divine character set
The Real in its self-disclosure through 99 Names — ar-Raḥmān (the Compassionate), al-Qahhār (the Overwhelming), al-Laṭīf (the Subtle). Each Name is a possible face of Being; each created being is the locus (maẓhar) of one or more Names. Corresponds to the Ten Sefirot as divine attributes — both are the infinite structured as a set of qualities through which it can be known.
III
Al-Aʿyān al-Thābita — The Fixed Archetypes
Permanent entities · Divine Ideas · Latent possibilities
The divine Ideas or archetypes that exist eternally within God's knowledge before being breathed into existence. Each created being has its "fixed entity" — its essential form in the divine mind — which determines what kind of vessel it is for the divine self-disclosure. Corresponds to Neoplatonic Forms and to the Kabbalistic notion of each soul's root in the divine mind.
IV
Al-Khalq — The Created World
The breath of the Compassionate · Nafas al-Raḥmān
The world as the Real's exhalation — the hidden archetypes given existence through the divine breath. Not separate from God, but not identical to God. The world is Real's self-knowledge made visible. The mirror in which the Absolute sees its own face — which is why the Perfect Human is necessary: without a conscious mirror, the self-disclosure is incomplete.

Fuṣūṣ al-Ḥikam — The Bezels of Wisdom

Ibn Arabi's most influential work — reportedly given to him in a vision by the Prophet — maps the divine wisdom (ḥikma) through 27 prophets, each embodying a particular facet of the divine self-disclosure. Each prophet is a "bezel" (faṣṣ) — the setting of a ring — through which a specific divine gem (quality or wisdom) shines. Selected chapters:

Prophet Wisdom (Ḥikma) Core teaching in Ibn Arabi's reading
Adam Divine Wisdom The first mirror — created in the divine image as the locus where Being knows itself through all its Names. The Perfect Human in primordial form.
Noah Transcendence Wisdom The paradox of warning: the people fled the call and thereby drew closer to God through the very mechanism of rejection. Tanzīh — the unknowable face of the Real.
Abraham Love Wisdom Ibrāhīm as Khalīl (intimate friend) — the lover whose identity interpenetrates the beloved's without merger or separation. The model of tawakkul (radical trust) as love.
Moses Exaltation Wisdom The divine speech in the burning bush: the Real manifests through the sensory world to be perceived. Revelation as tajallī — the divine using created forms to disclose itself.
Jesus Prophetic Wisdom The Word made flesh — pure divine breath that takes human form. Jesus as the supreme symbol of the Barzakh: fully divine and fully human simultaneously, neither collapsed into the other.
Solomon Sovereign Wisdom The ruler who unifies all kingdoms — as the Perfect Human unifies all levels of Being. The name of God that governs all other Names.
Muḥammad Singularity Wisdom The seal of prophets — the final and most complete bezel. The Muḥammadan Reality (al-Ḥaqīqa al-Muḥammadiyya) is the first light of creation and the archetype of the Perfect Human.

The Barzakh — The Imaginal World

Between the purely spiritual and the purely material, Ibn Arabi posits a third ontological realm: the Barzakh — the isthmus or intermediate world. This is not simply a metaphor for an in-between state; it is a precise metaphysical territory. The Barzakh is the world of imagination (ʿālam al-mithāl, also called ʿālam al-khayāl) — where spiritual realities take subtle bodies and material things are raised to symbolic significance.

The twentieth-century scholar Henry Corbin recognized in Ibn Arabi's Barzakh exactly the territory he called the Mundus Imaginalis — the Imaginal World, distinct from the imaginary (mere fantasy) and from the physical (gross matter). This is the world in which visions occur, where angels appear, where prophets receive revelation. Ibn Arabi himself received the Fuṣūṣ al-Ḥikam in this world — it was handed to him in a vision by the Prophet Muhammad.

The Barzakh is also where the dead reside between death and resurrection, where dreams reveal truths hidden from waking consciousness, and where the mystic in states of kashf (unveiling) perceives the inner face of things. It is the theater of the divine self-disclosure — the realm where Names become visible.

The Three Worlds — Ontological Hierarchy

ʿĀlam al-Arwāḥ — The World of Spirits
Pure spiritual reality · No spatial location · The divine Names in their essence
Angels as pure intellects; divine Names in their essentiality; the realm of the fixed archetypes. Corresponds to Kabbalistic Atziluth and the Neoplatonic Nous.
ʿĀlam al-Mithāl — The Imaginal World (Barzakh)
The isthmus · Mundus imaginalis · Where spirit takes form and matter is spiritualized
The intermediate realm: spiritual realities appear with subtle form; physical objects reveal their spiritual significance. The locus of visions, prophetic revelation, and mystical kashf (unveiling). Not spatial, yet extended. Not temporal, yet sequential. Kabbalistic Yetzirah; Tantric subtle body realm.
ʿĀlam al-Shahāda — The World of Witness
The physical world · Sensory reality · The densest self-disclosure
The material world as the outermost face of the Real's self-disclosure. Not "fallen" or evil — it is the Real in its most opaque mode, but still the Real. Kabbalistic Assiah; the alchemists' prima materia awaiting transformation.

Al-Insān al-Kāmil — The Perfect Human

The lynchpin of Ibn Arabi's entire system is the doctrine of the Perfect Human (al-Insān al-Kāmil). This is not primarily about a specific person, though the Prophet Muhammad is its supreme historical instantiation. It is a structural concept: the Perfect Human is the being that actualizes all the divine Names simultaneously — the point at which Being achieves complete self-knowledge.

Ibn Arabi draws on a hadith: "God created Adam in His image." This is not anthropomorphism — it means that the human being is the comprehensive image (ṣūra) of the Real, the only created being that can simultaneously embody all 99 divine Names. A stone embodies a few Names (al-Ṣamad, the Solid One); an animal more; the human potentially all of them — which is why the Quran says the angels were commanded to prostrate before Adam. The human capacity for comprehensive self-disclosure is greater than the angelic.

The Perfect Human is therefore the Real's mirror — the surface in which the Absolute sees its own face in completeness. Without a perfect mirror, the self-disclosure would be partial. The Great Work, in Ibn Arabi's framework, is the human being actualizing this comprehensive capacity: becoming the mirror in which Being knows itself as such.

This maps with precision to the Kabbalistic Adam Kadmon — the primordial divine human who contains all the Sefirot. Both are structural concepts: not merely an individual human being, but the archetype of comprehensive divine self-knowledge instantiated in a human form.
