The 5 Niyamas of Yoga: Meaning and How to Practise Them

The niyamas are the five personal observances of yoga: Saucha (cleanliness), Santosha (contentment), Tapas (discipline), Svadhyaya (study) and Ishvara Pranidhana (devotion or surrender). Patanjali lists them in Yoga Sutra 2.32 as the second of the eight limbs of yoga, right after the yamas. The yamas describe how you treat other people. The niyamas describe how you treat yourself and your practice.

What does niyama mean?

Niyama (नियम) comes from the Sanskrit root yam, to hold or restrain, with the prefix ni, which adds a sense of inward direction. It is usually translated as "observance" or "rule". Yama, from the same root, is the restraint you keep toward the world. Niyama is the one you keep toward yourself.

The sutra itself is short:

śauca santoṣa tapaḥ svādhyāya īśvarapraṇidhānāni niyamāḥ
Cleanliness, contentment, discipline, study and devotion to Ishvara are the niyamas. (Yoga Sutra 2.32)

They sit inside a larger list. In Yoga Sutra 2.29 Patanjali names the 8 limbs of yoga: yama, niyama, asana, pranayama, pratyahara, dharana, dhyana and samadhi. The first two are the ground the rest stand on. If you are new to the text, our short guide to what a sutra is explains how it is written.

Yamas and niyamas: the difference

The five yamas are about restraint in how you act toward others: Ahimsa (non-harming), Satya (truthfulness), Asteya (not stealing), Brahmacharya (moderation) and Aparigraha (not grasping). Patanjali calls them a "great vow" that holds regardless of place, time or circumstance (2.31).

The niyamas turn inward. They are habits you build: how you keep your body and space, how you meet what you have, how you practise, what you study and what you offer your effort to. A simple way to hold the two apart: the yamas are what you avoid doing to others, the niyamas are what you choose to do for yourself.

The five niyamas, one by one

1. Saucha: cleanliness

Saucha comes from shuci, clean or pure. The commentary by Vyasa, the oldest we have on the Sutras, describes two sides. The outer side is ordinary: wash, eat clean food, keep your space in order. The inner side is clearing the mind of what clouds it, such as pride, envy and resentment.

On the mat, saucha can be as plain as a clean mat and a tidy corner to practise in. Off the mat, it is noticing what you take in, from food to the news, and whether it leaves your head clearer or noisier.

Patanjali says more about saucha than you usually hear in class. In Sutra 2.40 its first fruit is a certain distance from your own body and less wish for contact with other bodies. Modern teachers mostly leave that part out, and it helps to know it is there.

2. Santosha: contentment

Santosha is sam (completely) and tosha (satisfied). Contentment means being at ease with what you have, instead of reaching for the next thing. Sutra 2.42 calls the happiness that comes from it unsurpassed.

Contentment sits fine next to ambition. You can work hard for change and still stop measuring your life against someone else's. On the mat, it is the day your hamstrings are tight and you fold as far as they allow today, without forcing the pose you had last week.

3. Tapas: discipline

Tapas comes from tap, to heat or burn. It is the effort you keep up when it would be easier to stop: getting on the mat on a grey morning, holding a pose for five more breaths, keeping a promise to yourself. Vyasa describes it as enduring opposites like heat and cold, hunger and thirst, and keeping vows.

There is a limit built in. The same commentary says tapas should not disturb the clarity of the mind, and in the Bhagavad Gita, austerity that torments the body is called the lowest kind. Tapas is steady heat. Grinding through pain is a different thing.

A practical start: pick one small habit, like ten minutes of practice in the morning, and keep it for a month. The old saying that tapas works best on one or two changes at a time holds up well.

4. Svadhyaya: study

Svadhyaya is sva (own) and adhyaya (study, reading, recitation). In the classical sense it means studying the texts that point toward liberation and reciting mantra, above all Om. Sutra 2.44 says it brings you into contact with the deity you are devoted to.

Most modern teachers read it as "self-study": watching your own habits and reactions with the same care you would give a text. Both readings lead to the same place in practice. You read something that matters to you, and you notice how you act. Writing a yoga journal is one concrete way to do the second part.

5. Ishvara Pranidhana: devotion or surrender

Ishvara means lord. Pranidhana means placing down, dedicating. Together: dedicating yourself, and the results of your actions, to Ishvara.

Who Ishvara is, Patanjali explains in Book 1 (1.23-1.27): a special self, untouched by suffering and karma, the first teacher, whose sound is Om. Sutra 2.45 says that samadhi, the final limb, comes from this devotion. Some readers take Ishvara as God, some as a personal chosen deity, some as the idea of something larger than the ego.

In practice, many teachers frame it as doing the work and letting go of the outcome: practise fully, then leave the result alone. That links it to abhyasa, steady practice, which Patanjali pairs with non-attachment in Book 1.

Kriya yoga: the last three niyamas

Tapas, svadhyaya and Ishvara pranidhana appear twice in the Sutras. Sutra 2.1, the opening line of Book 2, names these three as kriya yoga, the yoga of action. Patanjali gives it as the practical entry point: discipline, study and devotion, done every day. Our teacher Clare Nicholls covers this in her class on Sadhana Pada Sutra 1 and kriya yoga.

How to practise the niyamas day to day

You do not practise all five at once. Pick one for a week and give it a concrete form:

• Saucha: wipe your mat after practice and clear the space before you start.
• Santosha: in class, stop one step before your usual edge and stay there for the full hold.
• Tapas: practise at the same time each day for seven days, even if it is ten minutes.
• Svadhyaya: read one sutra in the morning and write two lines about it at night.
• Ishvara Pranidhana: before Savasana (Corpse Pose), drop the question of whether the practice went well.

Patanjali also gives a tool for when it goes wrong. Sutras 2.33-2.34 say that when a harmful thought takes hold, you cultivate its opposite, pratipaksha bhavana. Envy at a neighbour's backbend becomes a moment of santosha. Sitting with this in meditation makes it easier to catch.

Where the sources disagree

The niyamas are often taught as a fixed, ancient set. The picture is less tidy.

• Five or ten. Patanjali lists five. Later texts, among them the Shandilya and Varaha Upanishads and some hatha yoga texts, give ten niyamas, adding items like faith, charity, listening to scripture, modesty, mantra repetition and vows. The five in this post are Patanjali's.
• Study of texts or study of self. The classical commentaries read svadhyaya as scripture and mantra. "Self-study" as the main meaning is a modern emphasis. Both are useful, but the older meaning is the textual one.
• God or surrender. Patanjali's Ishvara is a specific being in his system. Modern secular yoga often reads Ishvara pranidhana as letting go of results. That reading works on the mat. It is still an adaptation.
• Purity as health. You will read that saucha purifies the body and that tapas burns off impurities. The Sutras speak of impurity in a spiritual sense. They make no medical claims, and neither do we.
• Rules or ideals. Some teachers treat the yamas and niyamas as preconditions: no asana until they are in place. Most modern schools, following Krishnamacharya's students, treat them as ideals you grow into alongside the physical practice.

To hear the sutra read and explained line by line, Clare Nicholls teaches Sadhana Pada Sutra 32 on the niyamas, part of our introduction to the Yoga Sutras of Patanjali.

Frequently asked questions

What are the 5 niyamas?

Saucha (cleanliness), Santosha (contentment), Tapas (discipline), Svadhyaya (study, often read as self-study) and Ishvara Pranidhana (devotion or surrender). Patanjali lists them in Yoga Sutra 2.32.

What does niyama mean?

Niyama means "observance" or "rule". It comes from the Sanskrit root yam, to hold or restrain, with the prefix ni. In yoga it names the five personal practices that make up the second limb.

What is the difference between yamas and niyamas?

The yamas are restraints in how you act toward others, such as non-harming and truthfulness. The niyamas are observances you keep toward yourself, such as cleanliness and discipline. Yama is the first limb of yoga, niyama the second.

Which limb of yoga is niyama?

The second of the eight limbs in Patanjali's Yoga Sutras, after yama and before asana, the physical postures.

Which niyama is the most important?

Patanjali does not rank them. He gives Ishvara pranidhana the largest result, saying in Sutra 2.45 that it leads to samadhi, and he makes the last three together, kriya yoga, the starting point of Book 2.

Do you have to believe in God to practise Ishvara Pranidhana?

Patanjali's text assumes a lord, Ishvara. Many modern teachers present it as dedicating your effort and letting go of the result, which anyone can practise. Both readings are common in yoga classes today.

Are there ten niyamas?

In some texts, yes. Later works such as the Shandilya Upanishad list ten niyamas, including faith, charity and mantra repetition. The five taught in most yoga classes come from Patanjali's Yoga Sutras.
