Slide 1: Patañjali and the Yoga-Sūtra
You’ve seen the word “yoga” thousands of times. It’s on gym schedules, wellness apps, Instagram bios, coffee shop noticeboards. There are probably three yoga studios within walking distance of wherever you’re sitting right now. Yoga, in the twenty-first century, is a multi-billion dollar global industry.
So here’s my question before we even begin: what if almost everything the modern world calls “yoga” has essentially nothing to do with what Patañjali actually wrote?
That’s not a provocation for its own sake. That’s what the text actually shows us — and by the end of this lecture, you’ll be able to read the Yoga-Sūtra on its own terms and see exactly where the gap opened up. But more than that, you’re going to encounter one of the most rigorous, sophisticated philosophies of mind ever produced in the ancient world. A system that asks questions about consciousness, suffering, and freedom that Western philosophy didn’t seriously tackle until the twentieth century — and in some respects, still hasn’t answered as precisely.
The tags on this lecture say Philosophy of Mind, Metaphysics, Indian Philosophy. All three are accurate. What Patañjali gives us is a complete metaphysical architecture — a theory of what the self is, why it suffers, and what it means to be genuinely free. That’s what we’re here to examine.
One thing to note before we go further: the name on the cover of this text is Patañjali. But whether that name refers to one person or two — whether there even was a single author — turns out to be one of the more fascinating scholarly puzzles in all of Indian philosophy. And that’s exactly where we’re going next.
Slide 2: One Patañjali or Two?
Here’s where it gets weird — and I mean that in the best possible way.
Ancient Indian tradition credits a single figure named Patañjali with two genuinely monumental works. The first is the Mahābhāṣya — a commentary on Pāṇini’s Sanskrit grammar, dated to approximately 150 BCE. The second is the Yoga-Sūtra, the text we’re studying today, dated to roughly 400 CE. The problem is sitting right there in those dates. That’s a gap of roughly 550 years. The same person cannot have written both.
Now, Adamson and Ganeri in Classical Indian Philosophy treat this as a settled scholarly question — they list the two Patañjalis as distinct entries in their index, the grammarian and the yoga philosopher, because modern scholarship is fairly clear that these are different people. What’s philosophically interesting is why the tradition merged them.
Think about what’s being claimed when you attribute both works to one genius. You’re saying: the man who mastered the structure of Sanskrit — the very architecture of thought and language — also mastered the structure of consciousness and liberation. That’s an extraordinarily appealing story. One mind, two mountains. And there’s something almost poetically coherent about it: if you understand language deeply enough, perhaps you understand the mind that generates language. If you understand the mind, perhaps you understand how to free it.
But the conflation was almost certainly a later tradition, and the most plausible explanation is that attributing the Yoga-Sūtra to the famous grammarian lent it greater antiquity and authority. This was not unusual in ancient India — texts were sometimes attributed to legendary figures precisely to signal their importance and trustworthiness.
What this means for us is actually quite liberating as scholars. We don’t need to know who Patañjali was to evaluate what he argued. The Yoga-Sūtra stands or falls on the strength of its philosophical claims — and those claims, as we’re about to see, are formidable.
So: one Patañjali or two? Almost certainly two. But the philosophy we’re examining belongs to neither the grammarian nor the legend. It belongs to the ideas themselves. And those ideas are worth taking very seriously indeed.
Slide 3: Historical Context of the Yoga-Sūtra
400 CE. Northern India. And the intellectual atmosphere is extraordinary.
This is not a period of philosophical isolation — it’s a period of fierce, productive collision. Brahmanical traditions, Buddhist schools, and Jain thinkers are all operating simultaneously, reading each other, challenging each other, sometimes borrowing from each other without fully admitting it. The Yoga-Sūtra emerges from this environment. You cannot read it as though it fell from the sky into a vacuum. It is a document in conversation — with Sāṃkhya metaphysics it inherits, with Buddhist psychology it sometimes mirrors, and with rival accounts of liberation it is quietly arguing against.
But before we get to any of that, we need to pause on something that the slide raises and that most students completely overlook — the question of what a sūtra actually is.
The word sūtra means thread. A thread. And that’s not decorative etymology — that’s a precise description of what you’re holding when you read this text. The Yoga-Sūtra contains 196 aphorisms. Some of them are a single line. Some are barely a grammatical clause. Here’s the second one, which happens to be the most important sentence in the entire text: Yogaś citta-vṛtti-nirodhaḥ. Five Sanskrit words. That’s it. That is Patañjali’s definition of yoga.
Now — a Western reader picks that up and thinks: right, compressed wisdom, like a proverb. I can work with this. But that’s not quite how it works. A sūtra is not a proverb. A proverb is designed to be understood immediately, to land with recognition. A sūtra is designed to be unpacked — slowly, carefully, over years, with a teacher. It is a mnemonic skeleton. The flesh, the muscle, the meaning — that comes through the commentary tradition. Without commentary, the Yoga-Sūtra is genuinely close to unintelligible in places. It’s intentionally compressed to the point of obscurity.
This is why the slide highlights Vyāsa’s Yoga-Bhāṣya, composed around 500 CE — roughly a century after the Yoga-Sūtra itself. Vyāsa’s commentary is not optional background reading. It is, for most of the tradition, inseparable from the text. When scholars talk about “Patañjali’s yoga,” they almost always mean Patañjali as read through Vyāsa. The two texts function as a single philosophical unit.
There’s something philosophically provocative about this. We’re used to the idea that a great thinker writes a text, and the text contains the thought. Patañjali’s system challenges that assumption at the structural level. The text requires interpretation to function. It is incomplete by design. Which raises a question worth sitting with: is that a limitation, or is it actually a feature? Is Patañjali telling us something about the nature of philosophical understanding itself — that it cannot be transmitted in writing alone, that it requires a living relationship between teacher and student?
That question is going to echo through everything we discuss today. Keep it in mind.
Slide 4: Citta-Vṛtti-Nirodha — The Core Formula
Let’s go back to that second aphorism, because this is the philosophical centre of gravity for everything Patañjali builds.
Yogaś citta-vṛtti-nirodhaḥ.
Yoga is the stilling of the fluctuations of the mind.
Three terms. The slide breaks them down, and I want to take each one seriously — because the precision here is not ornamental. Every word is doing philosophical work.
Citta — translated as mind-stuff, or the mental field. This is broader than what we typically mean by “mind” in English. It encompasses not just conscious thought but the entire field of mental activity — perception, memory, imagination, the deep impressions left by past experience. Think of it less like a computer processor and more like a vast, turbulent body of water. Everything that has ever happened to you, everything you’ve ever perceived or desired or feared, is present somewhere in the citta. It is the totality of your psychological existence.
Vṛtti — fluctuations, modifications, whirlpools. The slide uses that word “whirlpools” and I think it’s exactly right. A vṛtti is a movement in the citta, a disturbance on the surface of that mental lake. Patañjali identifies five types: valid cognition, error, imagination, sleep, and memory. Notice that sleep is in there — even in dreamless sleep, the mind is not truly still. It is still producing a kind of mental modification. The vṛttis are not just your anxious thoughts or your distractions. They are the basic operations of ordinary mental life.
Nirodha — and this is the one that requires the most care. The slide is precise about this: nirodha is not suppression. It is cessation, restraint, a radical quieting. The distinction matters enormously. Suppression implies forcing something down, holding it under — which would just create pressure, tension, a kind of psychological violence. Nirodha is something more like allowing the waves to settle completely. Not fighting the water. Letting it become still.
Put it together and you get something philosophically stunning. Patañjali is not saying: yoga makes you calm, or yoga reduces stress, or yoga improves your flexibility. He is saying: yoga is the complete cessation of all mental fluctuation. And the next aphorism — the one immediately following — tells us what happens when that cessation occurs: tadā draṣṭuḥ svarūpe avasthānam. Then the seer abides in its own nature.
This is where the slide’s philosophical point lands with full force. We ordinarily misidentify ourselves with our mental activity. You think you are your thoughts. You think you are your emotions, your memories, your perceptions. Patañjali’s claim is that this identification is a mistake — a profound, suffering-generating mistake. The vṛttis are not you. They are movements in the citta, which is itself a product of matter. Beneath all of that activity, there is something that simply sees — pure consciousness, puruṣa — and it has been there the entire time, obscured by the noise.
This is not a relaxation technique. The slide says it plainly, and it’s worth repeating: this is a metaphysical claim about the nature of the self. Patañjali is not offering you stress relief. He is telling you that what you take yourself to be is a case of mistaken identity — and that the entire apparatus of yoga, all eight limbs of it, exists to correct that mistake.
Now, a philosophically alert student at this point should be raising their hand — metaphorically at least — and asking: wait, how do you know there’s a pure consciousness underneath all the mental activity? Isn’t that just an assumption? And that’s exactly the right question. Because the answer requires us to go one level deeper, into the metaphysical foundations Patañjali inherits from the Sāṃkhya school. Which is precisely where we’re going next.
Slide 5: Sāṃkhya Foundations — Puruṣa and Prakṛti
Patañjali did not invent his metaphysics from scratch. He inherited it — and then adapted it in one crucial respect that we’ll get to in a moment.
The Sāṃkhya school is one of the oldest systematic philosophies in India, and its central move is a strict dualism. Not the kind of dualism most Western students are familiar with from Descartes — mind versus body, ghost in the machine — though there are surface similarities worth noting. Sāṃkhya dualism is between puruṣa and prakṛti, and the distinction is more radical than anything Descartes proposed.
Puruṣa — pure consciousness. The slide describes it as an eternal, unchanging, passive witness, and every one of those words is philosophically loaded. Eternal: it was never born and will never die. Unchanging: it has no states, no moods, no development. It does not learn, does not grow, does not suffer. Passive: this is the crucial one. Puruṣa does not act. It does not intervene in the world. It simply sees. It is pure witnessing awareness, with no content of its own.
And here’s something that trips up almost every Western student encountering this for the first time: in Sāṃkhya-Yoga, there is not one puruṣa. There are many. Each individual being has its own puruṣa — its own irreducible centre of pure consciousness. This is not the Advaita Vedānta view, where all consciousness is ultimately one universal Brahman. Patañjali’s universe is populated by a plurality of distinct, eternal witnesses. Liberation, as we’ll see when we get to kaivalya, means each puruṣa standing alone — not merging into some cosmic ocean of consciousness, but achieving its own radical isolation.
Prakṛti — primordial matter. Everything else. And I mean everything. The physical world, yes — but also the mind, the ego, the intellect, the senses. In Sāṃkhya-Yoga, your mind is not consciousness. Your mind is matter. Subtle matter, certainly — but matter nonetheless. The citta we were just discussing, the mental field with all its fluctuations? That’s prakṛti. Your thoughts are material events. Your emotions are material events. Even your sense of being a self — what Sāṃkhya calls ahaṃkāra, the ego-maker — is a product of prakṛti.
Sit with that for a moment, because it’s genuinely disorienting from a Western perspective. We tend to assume that consciousness is what the brain produces — that mind emerges from matter. Sāṃkhya inverts this completely. Matter and consciousness are two entirely separate, irreducible realities. Consciousness doesn’t emerge from matter. It was never part of matter. The confusion between them is precisely the problem.
Which brings us to what the slide calls the problem of misidentification — and this is where the whole system clicks into place.
Puruṣa, pure consciousness, somehow comes into proximity with prakṛti and begins to identify with it. It mistakes the movements of the mental field for its own experience. It thinks: I am perceiving this. I am feeling that. I am remembering, imagining, suffering. But none of those are puruṣa. Those are all vṛttis — fluctuations in the citta, which is prakṛti. The pure witness has confused itself with the thing it’s watching.
Adamson and Ganeri, working through this material in Classical Indian Philosophy, note that this creates a genuinely puzzling philosophical question: if puruṣa is truly unchanging and passive, how did it ever get entangled with prakṛti in the first place? How does something eternal and unaffected become confused? The tradition offers various answers, but the honest response is that Patañjali himself doesn’t fully resolve this — he’s more interested in the solution than the origin story. The entanglement is the given. Liberation is the goal.
And suffering — duḥkha, that word that also sits at the heart of Buddhist philosophy — arises directly from this misidentification. You suffer because you take yourself to be something you are not. You take yourself to be your anxieties, your desires, your losses, your achievements. All of that is prakṛti in motion. The puruṣa watching all of it is untouched, has always been untouched, and liberation means finally recognising that fact.
So the question becomes: how? If the misidentification is this deep — if even the mind that wants to be free is itself made of matter — what is the path out?
That’s exactly what Patañjali’s eight-limbed path is designed to answer.
Slide 6: The Eight-Limbed Path — Aṣṭāṅga Yoga
Here’s something worth pausing on before we walk through these eight limbs. Patañjali is facing a genuinely difficult philosophical problem. He’s just told us that the mind — the very instrument we’d normally use to think our way to freedom — is itself made of matter. It’s part of the problem. So how do you use a contaminated instrument to purify itself?
His answer is: you don’t start with the mind. You start with the body, with behaviour, with the outermost layer of human existence, and you work inward. Systematically. Progressively. Each limb creates the conditions for the next. You cannot skip ahead. You cannot do the inner work without first doing the outer work. This is not a philosophy of sudden enlightenment — it is a philosophy of disciplined, structured transformation.
The Sanskrit term is aṣṭāṅga — eight limbs. Not eight steps in a linear sequence you complete and leave behind, but eight dimensions of practice that operate simultaneously, each one supporting the others. Think of them less like rungs on a ladder and more like the roots, trunk, branches, and leaves of a single tree. They belong together.
The outermost two limbs are yama and niyama — ethical restraints and observances. The yamas include non-violence (ahiṃsā), truthfulness (satya), non-stealing, celibacy or continence, and non-possessiveness. The niyamas include cleanliness, contentment, disciplined effort, self-study, and surrender to Īśvara — a concept we should note carefully, because Patañjali’s yoga is one of the few Sāṃkhya-derived systems that introduces something like a god-figure, though Īśvara is not a creator deity but a special puruṣa untouched by any affliction, a kind of ideal of pure consciousness.
Why start with ethics? Because a mind consumed by greed, violence, or dishonesty cannot become still. The vṛttis generated by unethical living are too turbulent. You cannot meditate your way to liberation while simultaneously lying, stealing, and harming. The ethical foundation is not a moral add-on — it is a psychological prerequisite. Patañjali understands that character and consciousness are not separate domains.
Then come āsana and prāṇāyāma — posture and breath regulation. And here’s where we need to be honest about something, because this is where the modern world has completely inverted Patañjali’s priorities. We’ll address that directly in the next slide, but for now: in the Yoga-Sūtra, āsana gets three aphorisms. Three. Its definition is sthira sukham āsanam — posture should be steady and comfortable. That’s it. The elaborate physical practice of modern yoga? Patañjali doesn’t mention it. Āsana in this system means: sit still enough that your body stops being a distraction. Prāṇāyāma — working with the breath — is more developed, because breath regulation directly affects the mind. Control the breath, and you begin to influence the citta.
The fifth limb, pratyāhāra, is where the real inward turn begins. The word means withdrawal of the senses — the deliberate disengagement of attention from external objects. Your senses are constantly pulling consciousness outward, toward sounds, sights, sensations. Pratyāhāra is the practice of reversing that current. It’s not that you go deaf or blind — it’s that the senses stop commanding your attention. You become, in Patañjali’s image, like a tortoise withdrawing its limbs. The energy that was constantly flowing outward begins to collect inward.
And then the final three limbs — dhāraṇā, dhyāna, and samādhi — concentration, meditation, and absorption. These three form a unified inner practice that Patañjali calls saṃyama, and this is the engine of liberation. Dhāraṇā is fixing attention on a single object. Dhyāna is the sustained, unbroken flow of attention toward that object — what we might recognise as meditation in the deep sense. And samādhi is absorption, where the distinction between the meditator, the act of meditating, and the object of meditation begins to dissolve.
There are multiple levels of samādhi in Patañjali’s system — this is one of the most technically complex parts of the Yoga-Sūtra, and entire scholarly careers have been spent mapping them. But the trajectory is clear: each level of samādhi involves progressively less mental content, progressively fewer vṛttis, until the mind approaches complete stillness. And when it reaches that stillness — when citta-vṛtti-nirodha is actually achieved rather than just described — what remains?
That’s the question kaivalya answers.
Slide 7: Kaivalya — What Does Liberation Look Like?
The word kaivalya comes from kevala — alone, only, isolated. And that etymology is philosophically precise in a way that should stop you in your tracks.
Liberation, in Patañjali’s system, is not bliss. It is not union. It is not the dissolution of the self into something larger. It is aloneness. Puruṣa standing completely alone, fully disentangled from prakṛti, no longer confused about its own nature. The pure witness, finally witnessing only itself.
Now — the slide draws two crucial contrasts, and I want to spend real time on both of them because they correct two of the most common misunderstandings students bring to Indian philosophy.
The first contrast is with Buddhist nirvāṇa. Many students arrive assuming that all Indian liberation traditions are basically saying the same thing — that enlightenment means the self dissolves, that the ego is extinguished, that what we call “I” simply ceases. That’s a reasonable characterisation of certain Buddhist positions, particularly the anātman doctrine — the teaching that there is no permanent self to begin with. For Buddhism, liberation involves recognising the emptiness of the self you thought you had.
Patañjali is doing something categorically different. Kaivalya is not the extinction of the self. It is the puruṣa realising its own unchanging, luminous nature. The self doesn’t disappear — it turns out to be far more real, far more permanent, far more luminous than you ever suspected. What disappears is the misidentification with prakṛti. The puruṣa was never actually bound — it only appeared to be, because it was confused. Liberation is the correction of a cognitive error, not the annihilation of a self.
The second contrast is with Advaita Vedānta, the non-dualist school most associated with Śaṅkara. For Advaita, the ultimate reality is a single, universal consciousness — Brahman — and the individual self, the ātman, is ultimately identical with Brahman. Liberation means recognising that identity: aham Brahmāsmi, I am Brahman. The apparent multiplicity of selves is illusion — māyā. In the end, there is only one.
Patañjali flatly rejects this. Remember: in Sāṃkhya-Yoga, there are many puruṣas. Each is distinct, irreducible, eternal. Liberation is not merger with a universal consciousness — it is separation. Your puruṣa achieving its own kaivalya, standing alone in its own luminous isolation. Not absorbed into the ocean. Not extinguished. Alone.
This is philosophically striking because it means Patañjali’s liberated being is not in any obvious sense connected to other liberated beings. There is no cosmic reunion. No return to the source. Just each puruṣa, finally free, finally itself, finally still.
And what about karma, suffering, rebirth? The slide addresses this directly. The kleśas — the afflictions, the deep psychological roots of suffering — are what drive the cycle of rebirth. Patañjali identifies five: ignorance (avidyā), ego (asmitā), attachment (rāga), aversion (dveṣa), and clinging to life (abhiniveśa). These are not just bad habits. They are the structural conditions that keep puruṣa entangled with prakṛti across lifetimes. Kaivalya means the complete uprooting of all five. No more seeds of future karma. No more fuel for rebirth. The cycle simply stops — not because the self is destroyed, but because the confusion that kept it spinning has been permanently dissolved.
There’s something quietly radical about this vision of freedom. It doesn’t promise you happiness in the ordinary sense. It doesn’t promise connection, or love, or cosmic belonging. It promises something stranger and arguably more profound: the recognition that you were never actually what you thought you were, and that what you actually are has never suffered, never been bound, and never needed saving.
Whether you find that liberating or terrifying probably says something interesting about your own philosophical assumptions. And that, honestly, is exactly the kind of question Patañjali wants you to sit with.
Slide 8: Yoga Philosophy vs. Modern Yoga Culture
Alright, confession time.
When I first started seriously reading the Yoga-Sūtra, I had one of those genuinely embarrassing intellectual moments where you realise you’ve been confidently wrong about something for years. Because like most people in the modern West, my mental image of “yoga” was almost entirely physical. Poses. Sequences. Breathwork tied to movement. Maybe some ambient music and a Sanskrit word at the end of class.
And then I opened the text.
196 aphorisms. Āsana — the physical posture practice that generates billions of dollars annually and fills studios on every continent — receives exactly three of them. Three. Out of 196. And the definition offered in those three aphorisms is sthira sukham āsanam: posture should be steady and comfortable. That’s the complete teaching on physical practice in the Yoga-Sūtra. Sit still. Be comfortable. Don’t let your body distract you.
There is no sun salutation in Patañjali. No warrior pose. No flow sequence. The elaborate, athletically demanding physical practice that most people today identify as yoga developed centuries later, through entirely different textual traditions — the Haṭha Yoga Pradīpikā, composed around the 15th century CE, is the more relevant ancestor of modern physical yoga. Patañjali is not that tradition. He predates it by a thousand years and is doing something philosophically different.
Now — and the slide is careful about this, and so am I — this is not a critique of modern yoga. People derive genuine benefit from physical yoga practice. The breathing, the movement, the community, the discipline — these are real goods. Nobody is wrong for doing downward dog on a Tuesday morning. What we’re doing here is something more precise: we’re distinguishing between a cultural practice and a philosophical system, and insisting that the philosophical system deserves to be read on its own terms.
Here’s the scale of what gets missed when yoga is reduced to āsana. The yamas and niyamas — the ethical foundations — gone. Pratyāhāra, the withdrawal of the senses — gone. Dhāraṇā, dhyāna, samādhi — the entire inner architecture of concentration, meditation, and absorption — gone. Five of the eight limbs simply don’t appear in a typical yoga studio class. The system Patañjali actually constructed is a complete philosophy of mind, a rigorous metaphysical framework, and a systematic path toward liberation. Reducing it to the third limb is a bit like studying Plato’s Republic and only reading the bit about gymnastic education.
What happened? How did this occur? The honest answer involves colonialism, globalisation, the commodification of wellness, and a complex history of how Indian philosophical traditions were received, translated, and transformed in the nineteenth and twentieth centuries. That’s a lecture in its own right. But the key point for us today is this: the gap between Patañjali’s yoga and modern yoga culture is not a small interpretive difference. It’s a fundamental shift in what the word means.
The invitation the slide extends — and it’s the right note to strike — is not condemnation of what yoga has become. It’s curiosity about what it originally was. Read the text. Engage with the philosophy. Because what Patañjali actually wrote is stranger, more demanding, more intellectually rigorous, and ultimately more interesting than anything happening in a wellness studio. And it asks questions about consciousness, suffering, and the nature of the self that are worth taking seriously regardless of whether you ever sit on a mat.
Slide 9: Key Takeaways
Five things. Let’s make sure they’re genuinely lodged.
The first is the identity problem. The grammarian Patañjali and the yoga philosopher Patañjali are almost certainly two different people separated by roughly five centuries. The conflation was a later tradition, probably designed to lend the Yoga-Sūtra greater antiquity and authority. What this means practically is that we should approach the Yoga-Sūtra as its own philosophical project — not as an extension of Sanskrit grammar, not as ancient legend, but as a rigorous argument that stands or falls on its own terms.
The second is the philosophical core. Citta-vṛtti-nirodha — yoga is the stilling of the fluctuations of the mind — is not a wellness slogan. It is a metaphysical claim. It presupposes a theory of what the mind is, what consciousness is, and what the relationship between them should be. When Patañjali says the mind should be stilled, he means that the pure consciousness underlying all mental activity — puruṣa — should be allowed to abide in its own nature, no longer mistaken for the mental modifications of prakṛti. Liberation begins with a correction of identity.
The third is the dualist foundation. Everything in Patañjali’s system rests on the Sāṃkhya distinction between puruṣa and prakṛti — pure consciousness and primordial matter. Your mind is matter. Your ego is matter. Your memories, perceptions, and emotions are matter. What you actually are — puruṣa — is none of those things. It is the unchanging witness behind all of them. Suffering arises from confusing the witness with what it’s watching. This is not a Western dualism and should not be read through Descartes. It is something philosophically distinct and worth engaging with on its own terms.
The fourth is the structure of the path. The aṣṭāṅga — eight limbs — is a complete, integrated system moving from ethical foundation through physical discipline through sensory withdrawal to the inner practices of concentration, meditation, and absorption. The outer limbs prepare the conditions for the inner. You cannot shortcut the sequence. And the destination of the whole path — kaivalya, the complete isolation of pure consciousness from matter — is liberation understood as separation, not union, not extinction, but the puruṣa finally standing alone in its own luminous nature.
The fifth takeaway is perhaps the most practically urgent: read the text. The Yoga-Sūtra is one of the most influential philosophical documents in human history, and it is almost entirely unknown to the billions of people who practice something called yoga today. That gap is worth closing — not out of obligation to tradition, but because the questions Patañjali is asking about consciousness, identity, and freedom are genuinely among the most important questions philosophy can ask. And his answers, whether you ultimately accept them or not, are precise, rigorous, and philosophically serious in a way that rewards careful attention.
The Yoga-Sūtra is 196 aphorisms. Most of them are shorter than a tweet. The whole text takes about forty minutes to read. What it takes to understand — really understand — is considerably longer. But that’s true of anything worth understanding.
That’s Patañjali. That’s the Yoga-Sūtra. And that, for today, is where we leave it.
