Introduction: The Invisible Forces That Shape Us
Why do we sometimes find ourselves repeating the same behaviours, making the same mistakes or responding to situations in ways we cannot fully explain? Why do certain tendencies lie dormant for years, only to resurface when particular circumstances arise? And, perhaps most importantly, are we destined to remain prisoners of our past experiences?
These questions have occupied philosophers for centuries. In the ancient Indian tradition of Yoga, Patañjali offers a remarkably sophisticated explanation through the concepts of karma (action and its consequences), saṃskāra (formative impressions) and vāsanā (latent tendencies). Together, they describe how our actions and experiences leave subtle imprints that can influence our thoughts, behaviour and future experiences, sometimes long after the original events have passed.
In the Yoga Sūtras (4.7–4.9), Patañjali explores how these invisible impressions are formed, how they manifest under appropriate circumstances and how they can persist despite changes in time, place and even birth. Yet his teaching is not simply an explanation of why we behave as we do. It also offers a profound insight into the possibility of transformation.
Unlike the popular understanding of karma as a system of cosmic reward and punishment, the Yoga tradition presents a more intricate relationship between action, conditioning and consequence. It also makes an important distinction between being shaped by our past and being irrevocably controlled by it.
Through these three aphorisms, Patañjali invites us to look beyond the visible consequences of our actions and examine the subtle mechanisms that shape our lives. More importantly, he points towards a possibility that remains deeply relevant today: that by understanding our conditioning and loosening our attachment to it, we may begin to transcend the patterns that bind us.
What the Yoga Sūtras reveal about karma, habit, memory; and the possibility of freedom
Ancient Indian philosophy had a remarkably sophisticated idea about why we keep repeating ourselves. More than 1,500 years ago, the Yoga tradition described how actions leave invisible traces, how those traces shape what emerges in our lives, and how freedom begins when we stop feeding the cycle.
Why do we behave the way we do?
Why do certain reactions seem almost automatic? Why can an experience from long ago influence a decision today? Why do some tendencies appear to remain dormant for years before suddenly becoming active?
Modern psychology has its own vocabulary for these questions: conditioning, habit formation, implicit memory, behavioural patterns and learned responses. The ancient Yoga tradition approached a related problem through a very different conceptual framework.
In three remarkably compressed aphorisms Yoga Sūtras 4.7–4.9, Patañjali describes a world in which actions leave subtle traces, those traces do not all become active at once, and causal patterns can persist despite enormous changes in circumstances.
At the centre of the explanation are three Sanskrit concepts:
karma — action and its consequences
vāsanā — latent tendency or disposition
saṃskāra — formative impression or residual trace
Together they form an extraordinary theory of continuity. And, importantly, it is not a theory of fatalism. It is a theory of conditioning and the possibility of becoming free from it.
THE ACTION THAT DOES NOT BIND
Patañjali begins with a striking distinction.
कर्माशुक्लाकृष्णं योगिनस्त्रिविधमितरेषाम् ॥ ४.७ ॥
karmāśuklākṛṣṇaṃ yoginas trividham itareṣām
The karma of the yogin is neither white nor black; that of others is threefold.
At first glance, this sounds mysterious. What does it mean for karma to be “white” or “black”?
Classical commentators explain the ordinary threefold division as white, black, and mixed. White karma is broadly associated with beneficial or meritorious action. Black karma refers to harmful action and its painful consequences. Mixed karma describes the far more familiar human condition: actions in which motives and consequences may contain both constructive and destructive elements.
Most of us live in this mixed territory. But Patañjali introduces another possibility: the action of the yogin. According to the classical commentators, the yogin may continue to act. The yogin can teach, work, eat, speak, care for others and participate in the world. What changes is not necessarily the outward action. What changes is the relationship to the action and its result.
THE ACTION WITHOUT POSSESSIVENESS
King Bhoja, in his Rājamārtaṇḍa commentary, places particular emphasis on the yogin acting without desire for the fruits of action. This does not mean apathy. It does not mean that consequences cease to matter. And it does not mean abandoning ethical responsibility.
Rather, the action is no longer accompanied by the grasping thought: This result must be mine. The yogic ideal is action without possessive attachment to its fruits.
Vyāsa places this insight within a larger system. Ordinary action can produce a karmāśaya, a karmic deposit capable of producing future experience. But when the underlying afflictions—kleśas—and the identification that sustains them have been undermined, action loses this binding force.
This is a subtle idea. The goal is not necessarily to stop acting. It is to stop creating new chains through action.
Freedom does not necessarily mean doing nothing.
It means acting without continually creating another chain of bondage.
WHY DON’T ALL OUR TENDENCIES APPEAR AT ONCE?
The next aphorism takes the argument into even more fascinating territory.
ततस्तद्विपाकानुगुणानामेवाभिव्यक्तिर्वासनानाम् ॥ ४.८ ॥
tatas tad-vipākānuguṇānām evābhivyaktir vāsanānām
From that, only the latent dispositions corresponding to that fruition become manifest.
The crucial word is eva: only. Patañjali is making a very precise claim. We may carry many latent tendencies, but they do not all become active simultaneously. Only those appropriate to the particular circumstances become manifest.
The technical word is vāsanā (वासना). In modern conversation, vāsanā is sometimes translated simply as “desire”. But in the Yoga system, its meaning is considerably broader.
A vāsanā can be understood as a latent disposition—a tendency waiting for the appropriate conditions to express itself. It may influence attraction, aversion, behaviour, perception or habitual response.
Think of a field containing thousands of seeds. The fact that the seeds are present does not mean they will all grow today. Some lack water. Some lack sunlight. Some are dormant. Some encounter exactly the conditions they need. Yoga’s theory of vāsanās works in a similar way.

Experience and further action
This is why Patañjali’s formulation is so important. The present moment does not necessarily reveal everything that is latent within us. What becomes visible depends partly upon the conditions in which we find ourselves.
THE INVISIBLE MEMORY
Patañjali then asks an even harder question.
What happens when there is a huge gap between the creation of an impression and its later expression?
What if there is a change of body? A change of place? A change of time?
The answer appears in Sūtra 4.9.
जातिदेशकालव्यवहितानामप्यानन्तर्यं स्मृतिसंस्कारयोरेकरूपत्वात् ॥ ४.९ ॥
jāti-deśa-kāla-vyavahitānām apy ānantaryaṃ smṛti-saṃskārayor ekarūpatvāt
Even when separated by birth, place and time, there is continuity, because memory and formative impressions are of one form.
Three words are especially important: jāti — जाति; birth, embodiment or kind, deśa — देश; place, and kāla — काल; time. Patañjali is saying that these apparent gaps do not necessarily destroy causal continuity. Why? Because of the relationship between smṛti and saṃskāra.
MEMORY AND THE TRACE LEFT BEHIND
Smṛti (स्मृति) means memory or recollection. Saṃskāra (संस्कार) is a formative impression—a residual trace left by experience. The Yoga tradition distinguishes the two while connecting them causally.
An experience leaves an impression. That impression can remain latent. Under appropriate conditions, it can contribute to later recollection, recognition, inclination or habitual response.
In this model, the trace does not need to remain as a conscious memory. You do not necessarily need to remember an experience explicitly for its conditioning to have consequences. That distinction is important.
The Yoga Sūtras are not simply saying: “You remember everything.” They are proposing something subtler: Experience leaves traces, and traces can outlast the experience that produced them.
THE DEEPER QUESTION: WHAT CONTINUES?
This raises one of the most fascinating questions in Indian philosophy – If circumstances change radically, what exactly carries the continuity?
The Yoga answer is not necessarily a continuous autobiographical story. It is a causal continuity.
A person does not have to consciously remember an earlier experience for a latent tendency to remain part of the causal chain. This is where the ancient concept of saṃskāra becomes particularly interesting. We might picture it as an invisible imprint. You cannot see it directly. But under the right conditions, its effects become visible.
A habit. A reaction. An attraction. An aversion. A recurring pattern. A tendency that seems to emerge almost before conscious deliberation.
The Yoga tradition places these phenomena within a much larger metaphysical framework involving karma and rebirth. But the underlying insight is surprisingly intuitive: What we repeatedly experience and repeatedly do can leave traces that influence what we subsequently become.
THREE SŪTRAS — ONE ARGUMENT
Read together, the three aphorisms form a remarkably coherent sequence.
4.7 — ACTION
The ordinary person’s action participates in karmic causation. The yogin’s action no longer produces the same binding residue.
4.8 — MANIFESTATION
When karma bears fruit, only the tendencies appropriate to that particular fruition become active.
4.9 — CONTINUITY
Those latent tendencies can remain causally continuous despite changes in birth, place and time.
The sequence can therefore be expressed simply:
ACTION → IMPRESSION → LATENT TENDENCY → APPROPRIATE CIRCUMSTANCES → MANIFESTATION
And then the cycle can begin again. Unless something changes.
THE POSSIBILITY OF BREAKING THE CYCLE
This is where Patañjali’s teaching becomes more than an explanation of why things happen. It becomes a philosophy of liberation. If tendencies simply determine everything we do, there would be little point in practising Yoga. But that is not what Patañjali proposes.
The Yoga system is fundamentally concerned with removing the conditions that sustain bondage. The kleśas—the afflictions that distort perception and generate attachment, aversion and identification—are central to this process. As their roots are weakened, action changes.And as the causes of karmic accumulation are removed, the cycle loses its ability to reproduce itself indefinitely.
This is why the yogin’s karma in Sūtra 4.7 is described as neither white nor black. The yogin is not merely accumulating better karma. The deeper objective is to move beyond the mechanism of karmic bondage itself.
KARMA IS NOT FATE
This distinction is often lost when karma is discussed in popular culture. “Karma” is sometimes presented as a cosmic reward-and-punishment system:
Do something good → something good will happen.
Do something bad → something bad will happen.
The Yoga Sūtras describe something considerably more sophisticated. Karma is embedded in a network of causes, conditions, impressions and consequences. The tradition does not say that every event can be reduced to a simple moral transaction. Nor does it imply that human beings are helpless prisoners of their past. Quite the opposite. The entire discipline of Yoga assumes that transformation is possible. If the causes can be understood, they can be worked with. If tendencies can be observed, they need not automatically be obeyed. If attachment can be weakened, action can become less binding.
And if the roots of the process are removed, liberation becomes possible.
THE MODERN QUESTION
There is an intriguing resonance here with contemporary discussions of human behaviour. Modern science speaks about conditioning, neural pathways, implicit learning, habit loops and behavioural reinforcement.
The Yoga tradition speaks about saṃskāra, vāsanā, karma and kleśa.
These are not interchangeable scientific concepts, and it would be misleading to claim that Patañjali anticipated modern neuroscience. But both frameworks recognise something important: our present behaviour is not created entirely in the present moment.
We carry traces of what has happened before. Some are obvious. Others remain beneath conscious awareness. And circumstances determine which possibilities become active.
THE FINAL INSIGHT
Perhaps the most powerful message of Yoga Sūtras 4.7–4.9 is not about past lives at all. It is about freedom from automaticity. We inherit patterns. We acquire habits. We develop preferences. We react according to conditioning.
But Yoga asks a radical question: Must a tendency that arises within us necessarily control us?
Patañjali’s answer is no. The fact that something is latent does not mean it must remain powerful. The fact that a pattern has existed for a long time does not mean it is permanent. And the fact that circumstances trigger an old tendency does not mean we are obliged to reproduce the same response.
The yogic project is therefore not simply to accumulate better experiences. It is to understand the machinery by which experience becomes conditioning—and ultimately to become free from the machinery of bondage itself.
THE THREE WORDS TO REMEMBER
कर्म — KARMA; Action and its causal consequences – What we do participates in a chain of consequences.
संस्कार — SAṂSKĀRA; Formative impression – Experience leaves a residual trace.
वासना — VĀSANĀ; Latent disposition – The trace can become a tendency that manifests when conditions are appropriate.
Together:
- KARMA CREATES CONDITIONS
- SAṂSKĀRA LEAVES TRACES.
- VĀSANĀS BECOME TENDENCIES.
- YOGA SEEKS FREEDOM FROM THE BINDING CYCLE.
Key Take-Home
The past may leave its imprint, but it need not dictate our future.
The ancient Yoga philosophers were asking questions that remain remarkably alive:
Why do we repeat ourselves?
Why do some tendencies appear only under certain circumstances?
How much of our behaviour is conditioned?
Can the past determine the present?
And perhaps the most important question: Can we become free?
Patañjali’s answer is not that we have no conditioning. It is that conditioning does not have to be the final word.
Every action can leave a trace, every trace can become a tendency, and every tendency can shape how we respond to life. Yet awareness creates the possibility of a different response.
The deeper message of Yoga is not simply to understand why we repeat ourselves, but to discover how we can stop being governed by those repetitions.
