9.5 — Yoga: Patanjali's Eight Limbs
The Yoga Sutras of Patanjali, probably compiled somewhere between the second century BCE and the fourth century CE. 196 short aphorisms in four chapters, so compressed that they are almost unusable without a commentary — which is normal for the genre and is why the commentarial tradition matters as much as the text.
And they are the most complete practical training programme any tradition has produced.
The definition
The second sutra, and it is the whole thing:
Yogash chitta vritti nirodhah.
Word by word: yoga — union, or the discipline. chitta — the mind-stuff, the whole mental apparatus. vritti — movements, modifications, whirlings. nirodhah — stilling, restraint, cessation.
"Yoga is the stilling of the movements of the mind."
Then the third sutra: then the seer abides in its own nature.
And the fourth: otherwise, there is identification with the movements.
Four sutras and the entire diagnosis is complete, and it is Samkhya's (9.4): consciousness is identified with mental content, and when the content settles, the identification ends.
Note what is not in the definition: the body, posture, breath, flexibility or health.
The obstacles
Before the practice, the system names what is in the way, and the list is precise.
Five kleshas — afflictions.
Avidya — ignorance, which is the root of the other four. Specifically: taking the impermanent for the permanent, the impure for the pure, the painful for the pleasant, and the not-self for the self.
Asmita — I-am-ness. The identification of consciousness with the mental apparatus.
Raga — attraction. Dvesha — aversion. The pair from 6.5, and the same observation: they are one mechanism with two signs.
Abhinivesha — clinging to life, which the text says is present even in the wise and arises spontaneously.
And nine specific obstacles to practice, which read like a modern list: illness, dullness, doubt, carelessness, laziness, craving, misperception, failure to reach a stage, and instability once reached.
The eight limbs
And then the programme, which is called ashtanga — eight limbs.
They are limbs rather than steps, and the distinction matters: a body has all its limbs at once. The later ones cannot be reached without the earlier ones and the earlier ones are not abandoned.
1 and 2: Yama and Niyama
Covered in full in 8.11. Five restraints — not harming, truth, not stealing, restraint, not grasping. Five observances — cleanliness, contentment, disciplined effort, self-study, surrender.
And their position is the system's structural claim, identical to the Buddha's (6.6): conduct is the first two limbs, and nothing later works without them.
One sutra here is worth having on its own. When you are troubled by negative thoughts, cultivate the opposite. Pratipaksha bhavana — thinking of the opposite side. A specific, deliberate, usable technique: you do not fight the thought, you construct and dwell on its opposite.
3: Asana — posture
Three sutras. That is all it gets.
Sthira sukham asanam — the posture should be steady and comfortable.
Then: it is achieved by relaxing effort and letting attention go to the infinite. And then: after that, one is not disturbed by the pairs of opposites — heat and cold, and so on.
That is the entire treatment of posture in the foundational text of yoga (7.2). It is about being able to sit still without pain.
4: Pranayama — breath regulation
Regulation of the breath, and specifically the lengthening and smoothing of the exhale, the inhale, and the pause between them.
And the stated purpose: it removes the covering over the light, and makes the mind fit for concentration.
A caution the tradition itself gives and which is worth repeating: forceful breath practices done without instruction can produce genuine distress, and the texts are more careful about this than most modern classes are.
5: Pratyahara — withdrawal of the senses
The least discussed limb and one of the most useful.
The senses following the mind inward rather than being pulled outward by their objects. The image the tradition uses is bees following the queen.
Practically: the ability to stop being pulled by whatever is loudest. And in a world engineered specifically to capture attention, this is arguably the limb with the highest modern value and it is the one almost never taught.
6, 7, 8: Dharana, Dhyana, Samadhi
And these three are treated as one process at three depths — the text calls the trio together samyama.
Dharana — concentration. Holding attention on one object. The attention keeps leaving and you keep bringing it back (5.6, 6.9).
Dhyana — meditation. Attention stays on the object without needing to be returned. A continuous flow rather than repeated recovery.
Samadhi — absorption. The distinction between the observer, the observing and the object collapses.
The progression is not a technique change. It is the same activity becoming continuous, then complete.
The powers, and the warning
The third chapter lists siddhis — abilities said to arise from advanced practice. Knowledge of past and future, understanding the speech of animals, invisibility, knowledge of the moment of death, strength, and others.
And then the text does something admirable.
It says they are obstacles.
These are accomplishments for the outward-turned mind, and obstacles to samadhi.
A tradition that catalogues its own supernatural claims and then tells you they are a distraction is behaving better than most. Whatever you make of the powers, the instruction is: if you get them, they are not the point, and pursuing them is going the wrong way.
What is genuinely useful
Four things, stripped of everything else.
Conduct first. Two of the eight limbs are behaviour and they are the first two.
Cultivate the opposite. Pratipaksha bhavana is one of the few genuinely usable single techniques in ancient literature. You do not argue with the thought; you deliberately construct and inhabit its opposite.
Withdrawal of the senses is the limb of the century. The ability to disengage attention deliberately from whatever is pulling it is a trainable skill, and almost nothing in modern life trains it.
And the progression from returning-the-attention to attention-that-stays is the honest description of what practice actually feels like over years. You do not get better at concentrating. You spend less time recovering.
Where it differs from Buddhism
Because the practices look nearly identical and the goal is not.
Yoga's goal is kaivalya — isolation. The purusha, freed, abides alone in its own nature (9.4).
Buddhism's goal is nibbana — the cessation of the grip, and there is no isolated self left over (6.7).
Same techniques, opposite conclusions about what is there at the end, which is the disagreement that runs through this whole Part and which 15.2 says is still open.
What to carry from this page
Yoga is the stilling of the movements of the mind, and posture gets three sutras out of 196.
Cultivate the opposite rather than fighting the thought.
Learn to withdraw attention deliberately. It is the fifth limb, it is trainable, and it is the one skill the modern world most actively destroys.
And a tradition that lists its own miracles and calls them obstacles deserves to be taken seriously.
