Can You Think Your Way to God? Mysticism in Islamic Philosophy
You’re sitting in your room, and you start thinking about something strange. Everything around you—your desk, your phone, the tree outside—is made of smaller things: molecules, atoms, particles. And those particles? They’re made of energy, or fields, or something physicists don’t fully understand yet. So here’s a weird thought: when you look at a chair and your friend looks at the same chair, you’re both looking at the same chair. But what is that chair, really? Is it the solid thing you sit on? Or is it something much stranger—a bunch of tiny whirling things that only look solid because you’re too big to notice?
Now take that thought one step further. What if the same thing is true about everything? What if underneath all the different things in the universe—trees, people, planets, thoughts, feelings—there’s only one reality, and we’re just seeing it from different angles? This is the kind of question that has fascinated philosophers for thousands of years. And a group of them, working in the Islamic world between the 9th and 17th centuries, spent an enormous amount of time trying to figure out whether you could actually experience this oneness—not just think about it, but feel it, become it.
A Puzzle: How Does One Become Many?
Here’s the basic problem these philosophers were wrestling with. If you believe in God—one God, eternal, perfect, unchanging—how do you get from that perfect oneness to the messy, complicated world we live in? How does a perfect, simple Being create a universe full of rocks and cats and bad days? It’s not just a religious question. It’s a logical puzzle: how can something absolutely simple produce something complicated without becoming complicated itself?
The first Muslim philosophers who tried to solve this borrowed ideas from a Greek philosophy called Neoplatonism. The Greek philosopher Plotinus (who lived in the 200s CE) had argued that the universe doesn’t get “created” the way a carpenter builds a table. Instead, everything “flows” or “emanates” from the One, the way light flows from the sun. The sun doesn’t decide to shine; it just does, because that’s its nature. And the light that comes from it isn’t really separate from the sun—it’s the sun’s own radiance. Similarly, according to this view, the whole universe is like an overflow of God’s own being, not something God made from scratch.
Philosophers like Al-Fārābī (870–950 CE) and Avicenna (980–1037 CE) took this idea and ran with it. They were trying to be good Muslims while also being good philosophers, and they thought Greek philosophy could help explain Islamic beliefs. But they ran into a problem: if everything comes from God by emanation, like light from the sun, then everything is sort of connected to God. But you’re also supposed to worship God, and to love God, and to want to be close to God. How do you get closer to something you’re already part of?
The Two Paths: Reason vs. Experience
This is where the debate gets interesting. Some thinkers said: you get close to God by using your reason. Study philosophy, understand the logic of emanation, and you’ll see how everything fits together. That’s the rationalist path.
Others said: no, reason can only take you so far. To really know God, you need something else—a direct experience, an intuition, a kind of knowing that happens not in your head but in your heart. This is the mystical path.
Al-Ghazālī (1058–1111 CE) was one of the most famous defenders of the mystical path. He had been a brilliant philosopher and lawyer, but he went through a serious crisis. He wrote a book called The Incoherence of the Philosophers, arguing that reason alone couldn’t give you certainty about the most important things. He spent years wandering and practicing spiritual exercises. Eventually he found what he was looking for in Sufism—the mystical tradition of Islam. For Ghazālī, the point wasn’t to think about God. It was to know God, the way you know the taste of chocolate by eating it, not by reading about it.
But other philosophers thought Ghazālī gave up too easily. They wanted to have both: reason and mystical experience. The most ambitious of these was Ibn ‘Arabī (1165–1240 CE), sometimes called “the Great Master.” He developed a massive, complicated system that tried to explain everything. His central idea is called the “Unity of Being” (waḥdat al-wujūd). In English, that means “everything that exists is one thing.”
The Unity of Being: A Dangerous Idea
Ibn ‘Arabī’s idea sounds simple, but it’s actually very slippery. He wasn’t saying that everything is God—that would be pantheism, the belief that the universe itself is divine. He was saying something more subtle: that everything that exists is a manifestation of God’s being, like how all the waves in the ocean are still part of the ocean. The wave isn’t the same as the whole ocean, but it’s not separate from the ocean either. It is the ocean, taking a particular shape for a moment.
If you take this seriously, it changes how you see everything. That annoying kid in your class? They’re a manifestation of the same reality you are. That math problem you can’t solve? Also a manifestation of the same reality. There’s nothing that isn’t, at bottom, the same thing. Ibn ‘Arabī thought that the goal of human life was to realize this—not just to believe it, but to actually experience it. He called the person who achieves this “the Universal Man” (al-insān al-kāmil): a human being who has fully awakened to the fact that they’re not separate from everything else.
This got Ibn ‘Arabī in trouble. Some people accused him of saying that everything is God, which sounded like blasphemy. If a rock is God, why not worship rocks? If a bad person is God, why punish them? Ibn ‘Arabī had careful answers to these objections, but many people weren’t convinced. The debate continues to this day.
A Different Way: Light and Illumination
Not everyone was satisfied with Ibn ‘Arabī’s approach. A philosopher named Suhrawardī (1154–1191 CE) tried a different strategy. He said: instead of thinking about “being” and “existence,” think about light. For Suhrawardī, reality is made of degrees of light. God is the Light of lights, the purest, brightest source. Everything else is a dimmer version of that light, like shadows cast by a single flame. Your soul is a bit of that light that has become trapped in a dark body. The goal of philosophy—and of life—is to purify yourself so that your inner light can reconnect with its source.
Suhrawardī called this the “Philosophy of Illumination” (Ishrāq), and he wrote about it in a very strange style. He said that to really understand his book, you needed to fast for forty days and not eat meat. He was serious: he thought that some truths could only be grasped by someone whose body and mind had been purified. This wasn’t just a theory for him. He actually lived it, and it got him killed. The religious authorities accused him of heresy, and he was executed at age 36.
Suhrawardī’s idea of “knowledge by presence” became hugely influential. It’s the idea that some knowledge is direct and immediate, like knowing you’re in pain. You don’t infer that you’re in pain from evidence—you just know it, because you’re experiencing it. According to Suhrawardī (and later philosophers who followed him), this is how you can know God, too. Not by proving God exists, but by experiencing God directly. It’s not a philosophical argument. It’s something you do.
A Poem Against Reason
Not everyone was so optimistic about the whole project. The poet Rūmī (1207–1273 CE) was a Sufi mystic whose poems are still read and loved today. He was no fan of pure reason. He wrote:
The rationalists’ legs are just like stilts;
How unfixed and stolid are feet of wood!
For Rūmī, philosophers who thought they could reach God by thinking harder were like people walking on stilts—wobbly, clumsy, and likely to fall. He believed that true knowledge came from the heart, not the head. But notice: Rūmī wasn’t saying don’t think. He was saying don’t think that thinking is enough. Even he accepted that there was a kind of “universal intellect” that could grasp divine truths, but it wasn’t the same as your everyday reasoning.
Rūmī’s poems are full of this tension. He describes the soul as being trapped in this world, yearning to return to its source, like a reed that’s been cut from its riverbed and made into a flute. The flute’s music is the sound of longing. And the only way to satisfy that longing is to go through a spiritual transformation—to become the kind of person who can experience reality directly, not just think about it.
The Great Synthesis
After all these debates, there came a philosopher who tried to pull everything together. Mullā Ṣadrā (1571–1636 CE) is considered by many to be the greatest metaphysician in Islamic philosophy. He took ideas from Avicenna, Ibn ‘Arabī, Suhrawardī, and others, and wove them into a single system he called “Transcendental Theo-Sophy” (al-ḥikmat al-muta‘āliyah). That mouthful just means “a wisdom that goes beyond ordinary thinking.”
For Mullā Ṣadrā, the universe is not a collection of static things. It’s a constant flow, a process of change. Everything is moving, all the time, and the movement is toward God. Your consciousness, your body, your experiences—they’re all part of this motion. The goal of philosophy is not to have the right theory. It’s to move in the right direction, to become transformed by what you know. In his system, the knower and the known and the act of knowing become one. That’s knowledge by presence, taken to its furthest extreme.
Mullā Ṣadrā’s ideas are still studied and debated today, especially in Iran and India. His system is the most complete attempt to answer the original question: how do you get from the many to the One? His answer is: you don’t. The many is the One, in a way. You just have to learn to see it.
So What?
This might all sound very abstract. But the question these philosophers were asking is one that anyone can ask: “Is there a deeper reality behind the surface of things? And can I experience it?” They disagreed about the answer. Some said yes, through careful reasoning. Some said yes, but only through spiritual practice. Some said you need both. Some said forget about it and just live your life.
What’s interesting is that they all agreed on one thing: the surface of reality is not the whole story. The world you see with your eyes, touch with your hands, and think about with your brain is not the final truth. There’s something deeper. And the deepest thing they could imagine was oneness—a unity that includes everything, even you.
Next time you’re looking at a tree, or a friend, or even just your own hand, ask yourself: “Is this thing really separate from everything else? Or is it connected in a way I can’t quite see?” You might find that the question is more interesting than any answer.

Things to Think About
- If everything is one reality, does that mean your actions don’t matter? Or does it mean they matter more?
- Rūmī says reason is like “wobbly stilts.” But if you reject reason, how do you tell the difference between a genuine mystical experience and just a weird feeling?
- Could there be a third option—something between pure reason and pure experience—that these philosophers missed?
- Ibn ‘Arabī says the goal is to become the “Universal Man.” What would that look like in everyday life? Would anyone even recognize such a person?
Where This Shows Up
- In science: Quantum physics sometimes sounds like Ibn ‘Arabī when it talks about particles being “entangled” or not really separate.
- In poetry: Rūmī’s poems are some of the most widely read in the world, often quoted by people who don’t even know he was a Muslim mystic.
- In video games and movies: The idea of a “oneness” behind the world shows up in everything from Avatar to The Matrix to spiritual themes in games like Journey.
- In your own life: Have you ever been so absorbed in something—music, sports, a book—that you forgot where you ended and the experience began? That’s a tiny taste of what these philosophers were talking about.
