The mind as an active instrument
In the Yoga Sūtra, Patañjali describes the mind (citta) as an instrument that is always active. The forms this activity takes — thinking, imagining, remembering, interpreting, dreaming, perceiving — are called vṛttis, the modifications of the mind.
Consciousness (puruṣa) is unchanging. The mind, by its very nature, is subject to change. The practice of Yoga begins precisely with the capacity to distinguish between these two dimensions.
The mind is active by nature
According to Sāṃkhya, the mind belongs to material nature (prakṛti) and therefore:
- it does not stop moving,
- it cannot be forced to cease,
- and its movement is not, in itself, a problem.
Thus, the aim of Yoga is not to stop the mind, but to disengage consciousness from its fluctuations (YS I.2–4).
The mind continues to function, but it is no longer taken as identity.
Text and translation
I.5 — vṛttayaḥ pañcatayyaḥ kliṣṭākliṣṭāḥ
- vṛttayaḥ — fluctuations, mental movements
- pañcatayyaḥ — of five types
- kliṣṭāḥ — painful, disturbing
- akliṣṭāḥ — painless, non-disturbing
Translation:
“Fluctuations are of five types, and can be painful or painless.”
The five modifications of the mind
Patañjali identifies five vṛttis:
- pramāṇa — valid knowledge
- viparyaya — error or incorrect perception
- vikalpa — conceptual imagination
- nidrā — sleep
- smṛti — memory
Each of these can manifest as:
- comfortable, when it supports a functional reading of experience;
- uncomfortable, when it produces distortion, reaction, or turbulence.
This classification is descriptive, not moral. Yoga does not define “good” or “bad” vṛttis, but modifications with different effects on practice.
Working with the mind is not about perfecting mental states
If the mind is always active, it makes little sense to base practice on producing specific mental states, even if they appear calm, deep, or spiritual.
Yoga does not progress:
- by increasing comfortable vṛttis,
- nor by eliminating uncomfortable vṛttis.
Both belong to the mind. Neither, by itself, brings liberation.
What truly matters is not the type of vṛtti that arises, but how the practitioner relates to it.
Comfort also binds: the role of rāga
Patañjali identifies rāga (attachment to what is pleasant) as one of the five kleśas (YS II.3–9).
This means that:
- even when the mind is in a comfortable state,
- that comfort can generate attachment,
- and attachment strengthens identification with the mind.
- comfortable vṛttis do not guarantee stability or progress;
- they can, in fact, make the process more subtly conditioned.
The criterion of Yoga: seeing the mind as it is
Progress in Yoga arises from the capacity to:
- recognize the present modification,
- observe its impact,
- and not confuse oneself with it.
With practice, a stable perception emerges:
- the mind modifies → prakṛti in operation;
- consciousness observes → puruṣa remains.
As this distinction becomes clear and repeatedly recognized, there is a reduction in:
- the force of identification (asmitā),
- attachment (rāga),
- aversion (dveṣa),
- and the influence of past impressions (saṃskāras).
The mind remains active, but it is no longer the centre of identity.
The two currents within the mind
It is helpful to describe mental functioning as two flows:
- Comfortable flow — produces momentary clarity, but can generate attachment.
- Uncomfortable flow — produces challenge or turbulence, but can reveal patterns that needed to be recognized.
Neither of these flows is, in itself, a sign of progress or regression. Both are part of the natural activity of the mind.
Practice consists of:
- not amplifying,
- not fighting,
- not idealising either of these streams.
What matters is seeing — repeatedly and consistently — that both belong to the mind, not to consciousness.
The mind as a field of experience
For Yoga:
- every thought,
- every perception,
- every memory,
- every dream,
- and even deep sleep
is a vṛtti, because it leaves a recognizable trace afterward.
Understanding the vṛttis is not about “controlling the mind,” but about understanding the mechanism through which we mistake what the mind produces for who we are.
As this understanding becomes stable, the mind is no longer taken as “I.” And it is this shift — not the absence of vṛttis — that characterises progress in Yoga.
What are vṛttis in the Yoga Sūtra?
Vṛttis are the modifications or activities of the mind (citta). Whenever we think, imagine, remember, perceive or dream, the mind takes on a specific form — and that form is a vṛtti.
This means that the mind is continuously active. However, this movement is not an error, but a natural characteristic, since the mind belongs to prakṛti (nature).
The problem is not the vṛttis themselves, but identification with them. When consciousness (puruṣa) becomes confused with these modifications, the idea of identity based on the mind arises.
Thus, understanding vṛttis is recognising that they are mental phenomena, and not what we are.
Does Yoga aim to stop the mind?
No. The idea of “stopping the mind” is an imprecise interpretation of the teaching.
The mind, being part of prakṛti, is in constant activity and cannot be forced to cease completely. Trying to do so tends to generate more agitation.
When Yoga speaks of the cessation of fluctuations, it refers to the cessation of identification with the vṛttis, not to the elimination of mental activity.
The mind may continue to function, but it is no longer taken as identity. It is this shift that defines the practice.
What is the difference between mind (citta) and consciousness (puruṣa)?
The mind (citta) is an instrument of prakṛti: it is mutable, active and composite. It includes thought, memory, imagination and perception.
Consciousness (puruṣa), on the other hand, is unchanging and does not act. It does not produce content; it simply makes experience possible.
Confusion between these two dimensions leads to identification with the mind: “I think”, “I feel”.
Yoga consists in clearly distinguishing: the mind changes, consciousness observes. This distinction is progressively stabilised.
What are the five types of vṛttis?
Patañjali identifies five types of mental modifications:
pramāṇa (valid knowledge), viparyaya (error), vikalpa (imagination), nidrā (sleep) and smṛti (memory).
These categories cover all mental activity. Any experience we can describe falls into one of these forms.
Even sleep is considered a vṛtti, because it leaves a recognisable trace afterwards.
This classification is not moral, but descriptive. It serves to understand how the mind functions.
What does it mean that vṛttis can be painful or non-painful?
Vṛttis can be kliṣṭa (afflictive) or akliṣṭa (non-afflictive), depending on their effect on experience.
They are afflictive when they reinforce ignorance, attachment, aversion or identification. They are non-afflictive when they allow greater clarity.
However, no vṛtti, by itself, leads to liberation. Even the most stable or pleasant ones still belong to the mind.
Yoga does not aim to replace some with others, but to understand the mechanism of identification.
Why can the mind not stop moving?
The mind belongs to prakṛti, which is dynamic by nature. Everything that belongs to nature is in constant transformation.
Thus, mental activity is neither optional nor an error — it is inevitable.
Trying to force the mind to stop completely goes against its constitution and tends to create conflict.
What can change is not the movement of the mind, but the way we relate to it.
What is the role of attachment (rāga) in vṛttis?
Rāga is attachment to what is pleasant. It arises when a comfortable experience is registered and becomes desired or repeated.
In the context of vṛttis, this is important because even calm mental states can generate attachment.
This shows that comfort is not a reliable criterion of progress. It can reinforce identification with the mind.
For this reason, Yoga includes vairāgya (detachment), not as rejection, but as freedom from dependence.
Does the practice of Yoga consist in improving mental states?
No. Although the mind may become more stable, this is not the main aim.
If practice is oriented towards producing pleasant states, it remains centred on vṛttis.
Yoga proposes observing both comfortable and uncomfortable states without identification.
What matters is not the type of experience, but the relationship to it.
How does one work with vṛttis in practice?
The first step is to recognise the present vṛtti — thought, memory, imagination, etc.
Instead of reacting or trying to control it, the practitioner observes. This observation includes noticing the impact of the vṛtti.
With practice (abhyāsa) and detachment (vairāgya), a clearer relationship with the mind develops.
The mind remains active, but is no longer taken as identity.
How does understanding vṛttis lead to liberation?
Understanding vṛttis allows one to see that all mental activity belongs to prakṛti.
When this understanding becomes stable, consciousness (puruṣa) no longer identifies with the mind.
This reduces the causes of suffering, which depend on that identification.
Liberation (kaivalya) does not result from the absence of mind, but from the clear distinction between the observer and what is observed.
Conclusion
Patañjali shows that the problem is not in the vṛttis, but in identification with them.
The mind moves because it belongs to prakṛti; consciousness remains because it is puruṣa. The path of Yoga arises precisely from this distinction.
When the practitioner learns to recognize each modification of the mind as a natural event — comfortable or uncomfortable — and no longer takes it as identity, a stable clarity emerges: the mind experiences; consciousness witnesses.
Thus, understanding the vṛttis is not about shaping the mind according to an ideal, but about realising that all its activity belongs to Nature.
When this vision becomes established, inner freedom no longer depends on mental states — and that is where Yoga truly begins.
