Imam Ali (AS) asked a question that sounds simple until you actually sit with it: "Kayfa ya'rifu ghayrahu man yajhalu nafsah?" — How can one who is ignorant of himself come to know another? The nearest reality to any of us is our own self. And yet most of us have never really looked.
I want to draw out what this saying is actually claiming, because it's easy to hear it as a nice piece of moral advice — "know yourself first" — and miss that it's making a much sharper distinction: between two entirely different kinds of knowing.
Two Kinds of Knowing
There is theoretical, intellectual knowledge — the kind you get through reflection, reasoning, and demonstration. You study, you attend classes, you read books, and you arrive at a conclusion: this must be true. That's real knowledge. It's not nothing. But it is not the only kind there is.
Then there is experiential or witnessed knowledge — maʿrifah shuhūdī, or maʿrifah dhawqī, "tasted" knowledge. This isn't arrived at by argument. It's arrived at by direct observation, by witnessing. The classic example: you see smoke rising somewhere and you reason, correctly, that there must be a fire. That's theoretical knowledge — sound, but indirect. Then there's actually seeing the fire. That's an entirely different order of knowing, even though both are "true."
The Qur'an itself seems to mark this distinction. Faith in the unseen is one level — "They believe in the unseen" (Al-Baqarah 2:4) — and certainty, yaqīn, is another, higher level, because certainty belongs to the one who witnesses. Sound theoretical knowledge is faith. Witnessed knowledge is certainty. Both are legitimate; they are not the same thing.
This distinction isn't limited to self-knowledge. It runs through everything, including knowledge of God. Amir al-Mu'minin was once asked whether he had seen the God he worships. He answered: "Lam a'bud rabban lam arah" — I do not worship a Lord I have not seen. Obviously this isn't ordinary sight — God is not a body, "there is nothing like unto Him." So what kind of seeing is this? It's the kind of seeing a person has to develop a capacity for — a vision entirely unlike looking at walls and doors, which even animals can do.
Allamah Tabataba'i makes this vivid in his treatise on wilāyah (divine guardianship / authority) — I'm thinking of Risalat al-Wilayah and its Persian commentary, Tariq-e Irfan. He gives the example of a city you've never visited. You can know a great deal about it — its climate, its streets, its geography — and be completely certain it exists. But you cannot say "I have seen it" until you've actually gone there. Knowledge of God's existence and attributes is one thing; the meeting with God, liqāʾ Allāh, is something else entirely — and a person doesn't even know what that phrase means until they've tasted it. Mirza Jawad Agha Maleki Tabrizi makes the same point in his own treatise on liqāʾ Allāh: the traveler on this path can't even conceive of what it is at the outset. He just has to trust it's real, and keep walking, until he sees for himself.
Why Self-Knowledge Comes First
This is what gives the hadith "Man 'arafa nafsahu faqad 'arafa rabbah" — Whoever knows himself has known his Lord — its real weight. It's not a throwaway line. The claim is precise: to whatever degree you have witnessed your own soul, to that same degree you have witnessed God. Self-knowledge isn't a preliminary exercise before the real work of knowing God begins. It's the same axis. The soul has degrees, stations, layers — and your progress through them is, at once, your progress in gnosis of the divine. So the question "who am I?" isn't idle. And most people never ask it. Look at how strange this is: an ant has legs it never fashioned for itself. A mosquito has wings and a proboscis it never designed. Look at your own hand, your own face in a mirror — did you make yourself this way? No. Something else made you. So then: who is this being? Where was I before this? Where am I now, really — not just "earth," not just "the material world," but where? Where am I going? Who brought me here, and who will take me away?
There's a parable that captures this well: a ship moving across the sea. The sun rises, and one by one the passengers wake and go about their business — the helmsman steers, the lookout keeps watch, the cook cooks. Then someone stops and asks: where, actually, are we going, in this vast sea? He asks the sailor — doesn't know. The captain — doesn't know. The lookout — doesn't know. A great question mark appears on the deck. And then, one by one, everyone simply forgets the question and goes back to their tasks. That ship is us — passengers on the earth, moving through the vast sea of space, almost never stopping to ask where we're headed or what any of this is for.
Your Soul Is a Book You've Never Opened
There's a second saying worth sitting with: whoever is unaware of the scroll — the ṣaḥīfa — of his own soul cannot draw benefit from any book or treatise. Your soul is described here as a book with many pages, many layers, many stations. There are worlds inside you that you have never so much as glanced at, and until you do, no amount of outside reading will get you very far. You can study, you can even become a great scholar — a marjaʿ (source of emulation) — through real intellectual toil, and that is genuinely valuable. But it is not the same as witnessed knowledge, which is a direct vision of realities rather than a conclusion about them.
There's a striking old parable — not from the Islamic tradition, but one that makes the point well — about the gods debating where to hide the deepest secrets from humanity. Bury them in the ocean? He'll dive for them. Bury them in the earth? He'll dig them up. Hide them in the heavens? He'll find a way there too. In the end, they hide the secret inside the human being himself — because that is the one place he never thinks to look. He goes after everything except himself. Notice: most people can sit with a friend until sunrise in conversation, but can't sit alone with themselves for ten minutes. That's not an accident. It's evidence that we are, in some deep sense, fleeing from ourselves.
Knowing a Name Versus Having It
Here's where the distinction sharpens into something practical. Take the divine Name al-Muḥyī, the Life-Giver, derived from al-Ḥayy, the Living. Any of us could give a reasonably good account of what al-Ḥayy means. That's theoretical knowledge of the Name. But Prophet Jesus (AS) brought the dead to life — not because he knew what al-Muḥyī meant, but because he had become a locus where that Name actually manifested. Imam Ali (AS) said, "I cause death and I give life," for the same reason. Or consider the dentist and the patient. The dentist can tell you exactly which nerve in which tooth is causing your pain — he knows the pain perfectly. But he doesn't have it. You do. Knowing and possessing are not the same thing, and this is exactly the gap between saying "I know that a God exists" and saying "I have God."
This is also, incidentally, why people can talk endlessly about the Prophet (SAWW) or about Imam Ali (AS) and still not really know them. There's a telling exchange between two clerics: one says, "The Prophet was just like you and me — except he was told to speak, and we weren't." That's theoretical knowledge wearing the costume of reverence. It has nothing to do with witnessing who the Prophet (SAWW) actually was.
Some Things Cannot Be Translated Into Words
Once a person does move from theoretical to witnessed knowledge, a new problem appears: the knowledge becomes very hard, sometimes impossible, to communicate. Bayazid Bastami — who, notably, served as the water-carrier in the household of Imam al-Sadiq (AS), one of many disciples who used ordinary pretexts like this to receive training under conditions of taqiyyah (prudent concealment) — said that if the Divine Throne, which contains all the heavens and the earth, were multiplied a million times over and placed in one corner of the gnostic's heart, the gnostic wouldn't even feel it. Ibn Arabi adds that Bayazid was only describing his own station — the true gnostic's capacity goes further still. Ibn Arabi has his own treatise on this, Asrar al-Khalwah — the Secrets of Seclusion — cataloguing the worlds a person passes through in spiritual retreat, one after another, each with its own character. And his conclusion is the crucial part: all these worlds, in the end, are within your own soul. You are not touring some external cosmos. You are exploring yourself.
There are accounts from later mystics that gesture at what this can feel like on the near side of experience — visions of one's own self, states that pass through a person almost without their noticing. Sayyid Ali Khan Qazi, teacher of Allamah Tabataba'i, once described stepping out of a room and seeing himself standing in the veranda, studying his own face and noticing a mole he'd never registered before. Sayyid Hashem Haddad, exhausted and fasting, once left his house after a painful family argument and found, walking in the desert, that he had separated from his own body — the harsh words aimed at him were landing on that outer self, while his real self remained untouched. These are glimpses, not full disclosures. Higher than this, there are things that genuinely cannot be put into words — not because the person is being cagey, but because there's nothing on this side of language that the experience could be translated into. Allamah Tabataba'i, asked once by a close friend to describe his own secrets, is reported to have simply said: "How could I possibly tell you my own secret? It cannot be told." It isn't a guarded military code waiting to be leaked. It's inward, and there's no outward form for it to take.
When someone tries anyway, the results can be disastrous. Mansur al-Hallaj said "Ana al-Haqq" — I am the Truth — and was heard to be claiming divinity, and was killed for it. But by every account his words meant something else entirely, something that simply does not survive translation into ordinary speech.
Here's a small, almost embarrassingly ordinary way to feel the size of that gap: try to describe what chicken tastes like. Not compare it to something else — actually describe the taste itself, in words, to someone who has never eaten it. You can't. You've eaten it a hundred times, and you still can't say what it tastes like. That's the distance between theoretical and witnessed knowledge in miniature. Multiply that by an infinite factor and you're somewhere near what it means to witness one's own soul, let alone to witness God.
The Task
None of this is a reason to abandon study, reflection, or argument — theoretical knowledge is real knowledge, and it's the necessary door into everything else. But it is a door, not the room itself. Until a person turns the pages of the book that is his own soul, no other book — not even the Qur'an — will yield more than a fraction of what it holds. The task in front of every one of us is the plainest and hardest one there is: to actually go and look.
