Nauli Kriya: Meaning, Types, Steps, Benefits & Precautions

Nauli Kriya is one of yoga’s most striking practices to watch and one of its most demanding to learn. With the breath held out, the abdominal muscles are isolated and rolled side to side, creating a movement that looks almost impossible. It’s part of the Shatkarmas, yoga’s traditional six cleansing practices — and it asks for patient preparation through Uddiyana Bandha and Agnisara Kriya first. In this guide, we’ll meet Nauli Kriya with care, walk through the build-up sequence, and be honest about who should approach it and who should wait.

Nauli (also called Nauli Kriya or Nauli yoga) is a Hatha Yoga cleansing technique where you hold the breath out, isolate the two long abdominal muscles (rectus abdominis), and roll them from side to side like a wave. It is one of the six Shatkarmas. It is traditionally practised to support digestion and build core control, and should be learned from a qualified teacher.

What Is Nauli? Meaning in English

Nauli in English is usually described as “abdominal churning” or “abdominal rolling.” The word comes from the Sanskrit nala, meaning a tube or pipe, because the isolated abdominal muscle stands out like a vertical tube. Kriya means action or process. So the Nauli meaning is simply “the churning action of the abdomen.”

While doing Nauli Kriya, the organs in the stomach are moved vertically and transversely, creating a wave-like movement. You can imagine it like a boat rolling on a rough sea.

Nauli in the Classical Yoga Texts

In the Gheranda Samhita (1.52), Nauli is called Lauliki. The text describes moving the stomach and intestines with force from one side to the other, and says this practice removes disease and strengthens the digestive fire.

The Hatha Yoga Pradipika (2.33–2.34) describes it this way: with the shoulders bent forward, rotate the abdomen left and right with the speed of a whirlpool. The text calls Nauli the crown of Hatha Yoga practices and says it awakens weak digestion.

Nauli also has a practical role in the Shatkarmas. It is needed to perform Basti, the yogic colon cleanse, in which water is drawn into the large intestine using the suction created by Uddiyana Bandha and Nauli.

Note: The classical texts describe Nauli as a remedy for many diseases. Modern scientific research on Nauli is still limited, so these descriptions should be read as traditional teachings, not medical claims.

Bandhas: A Must-Know Before Doing Nauli Kriya

Energetic locks are known as Bandhas. These locks are physical contractions that support the organs in the abdomen, spine, and pelvis. Bandhas protect the body during practices that put pressure on the core region. Before learning Nauli, it is important to be comfortable with the three Bandhas below.

1. Mula Bandha (Root Lock)

In Sanskrit, “mula” means root and “bandha” means lock. Mula Bandha is a gentle lift of the pelvic floor, the muscles between the genitals and the anus.

Steps to follow:

• Sit comfortably with your spine straight.
• Gently contract and lift the pelvic floor, as if you were trying to hold back urine. Only imagine this action. Don’t practise by stopping the flow while actually urinating, as this can affect bladder health.
• Try to isolate the contraction at the perineum (the area between the genitals and anus) without squeezing the anal sphincter.
• Sitting with one heel pressed gently at the perineum, as in Siddhasana, can help you feel the right spot.
• Hold for a few seconds, then release. With practice, you’ll be able to hold it longer and more softly.

2. Uddiyana Bandha (Upward Abdominal Lock)

Steps to follow:

1. Stand with your legs a little apart.
2. Bend your torso forward and keep your hands on your thighs.
3. Take a deep inhalation through the nose, followed by exhalation through the mouth.
4. Contract the abdominal muscles fully to push maximum air out of the lungs.
5. Relax the abdominal region.
6. Expand the rib cage as if you are inhaling, but don’t actually breathe in. This pulls the abdominal organs and muscles up into the chest area, and the stomach becomes hollow.
7. With the chin lock, hold your breath out for 10–15 seconds. If you are doing it for the first time, hold for less.
8. Slowly release the abdominal region.
9. Raise your head.
10. Inhale as usual.

Precautions:

• Uddiyana Bandha must be practised on an empty stomach.
• It is done after exhalation, never after inhaling.
• It is usually combined with Jalandhara Bandha (the chin lock).

3. Jalandhara Bandha (Chin Lock)

Jalandhara comes from “Jal,” meaning net or web, and “Dhar,” meaning to hold or restrict the flow.

Steps to follow:

1. Sit in a comfortable position with your hands on your knees.
2. Take a deep inhalation through your nose and hold your breath.
3. Drop the chin down close to the chest, creating a double chin.
4. At the same time, lift the sternum (breastbone) up toward the chin.
5. Keep your shoulders relaxed, away from the ears.
6. Hold for as long as is comfortable.
7. Slowly lift your chin and exhale.

In Nauli practice, Jalandhara Bandha is done with the breath held out instead of in.

Precautions:

• Don’t hold your breath for too long.
• Always lift your head fully upright before you breathe in.

Agnisara Kriya: The Key Preparation for Nauli

Agnisara comes from “Agni,” meaning fire, and “sara,” meaning to wash or cleanse. This kriya is said to awaken the digestive fire, and it builds the abdominal control you need for Nauli.

Steps to follow:

1. Come into the standing position of Uddiyana Bandha, with the breath held out.
2. Without breathing in, quickly pump the abdomen in and out.
3. Do 10–15 pumps, or as many as you comfortably can, in one breath hold.
4. Release the abdomen, stand up, and breathe in slowly.
5. Take a few normal breaths and repeat for 3–5 rounds.

With regular practice, you’ll be able to do more pumps in each round. Practise Agnisara daily for a few weeks before moving on to Nauli.

Types of Nauli Kriya (नौली क्रिया के प्रकार)

How many types of Nauli Kriya are there? Nauli Kriya has 4 types, learned one after the other:

Some teachers count only three types and treat the rotation as the full practice that combines them.

How to Do Nauli Kriya: Step-by-Step Guide

Once you are comfortable with Uddiyana Bandha and Agnisara Kriya, you can begin this Nauli technique. Learn each stage fully before moving on to the next.

1. Madhyama Nauli (Central Nauli)

In Madhyama Nauli, both the left and right rectus abdominis muscles are contracted together, so they stand out as one vertical column in the centre of the abdomen.

Practice tips:

1. Stand with your feet apart and knees slightly bent. Place your hands on your thighs.
2. Inhale through the nose, then exhale fully through the mouth.
3. Hold the breath out (Bahya Kumbhaka) and come into Uddiyana Bandha, drawing the abdomen in and up under the rib cage.
4. Press your hands firmly on your thighs and push the lower centre of the abdomen forward. The two rectus muscles will stand out together in the middle.
5. Hold for a few seconds.
6. Release the muscles, then release Uddiyana Bandha.
7. Stand up and breathe in slowly.
8. Take a few normal breaths before the next round.
9. Repeat 3–5 times, as per your capacity.

2. Vama Nauli (Left Nauli)

In Vama Nauli, only the left rectus muscle is isolated and seen on the left side of the abdomen.

Practice tips:

1. Follow the steps of Madhyama Nauli until the central muscles stand out.
2. Shift your weight slightly to the left, press more with your left hand on your left thigh, and relax the right side of the abdomen.
3. The left muscle comes forward while a hollow forms on the right side.
4. Hold for a few seconds.
5. Release the muscles and Uddiyana Bandha, stand up, and breathe in deeply.
6. Repeat as per your capacity.

3. Dakshina Nauli (Right Nauli)

In Dakshina Nauli, all the steps of Vama Nauli are repeated. The only difference is that you press more with your right hand and isolate the right muscle, bringing it to the front.

4. Nauli Chalana (Abdominal Rotation)

This is the complete form of Nauli Kriya.

Practice tips:

1. Come into Madhyama Nauli.
2. Move the muscles from the centre to the left, then to the right, and back to the centre in one smooth, continuous wave.
3. Start with 3–5 rotations in one direction.
4. Release, stand up, and breathe normally.
5. After resting, rotate in the opposite direction.

How long does it take to learn Nauli? Most people need a few weeks to a few months of daily practice. Don’t rush to the next stage.

Common Mistakes to Avoid

• Breathing in during the hold: Keep the breath out the whole time.
• Breathing in before releasing the muscles: Always release the abdomen first, then inhale.
• Practising after eating: This can cause cramps and nausea.
• Forcing the movement: Nauli comes from relaxation and control, not force.

Benefits of Nauli Kriya

Here are the main Nauli Kriya benefits, based on yoga tradition and the experience of practitioners. They support good health but are not a replacement for medical treatment.

1. Improves Digestion: The churning massages the stomach and intestines. In yoga tradition, Nauli strengthens agni (the digestive fire), helping food digest properly.

2. Increases Appetite: When practised regularly and correctly, the stomach feels light and free of heaviness, and appetite improves.

3. Helps with Constipation and Gas: The rolling action encourages regular bowel movements and helps release trapped gas.

4. Massages the Abdominal Organs: The movement stimulates the area around the stomach, liver, pancreas, spleen and intestines.

5. Builds Core Strength and Control: Nauli trains you to control each part of the abdominal wall separately, building deep core awareness.

6. Improves Breath Control: Holding the breath out and lifting the diaphragm builds awareness and control of the breathing muscles, which supports pranayama.

7. Balances the Doshas: According to yoga and Ayurveda, Nauli helps balance Vata, Pitta and Kapha, especially in the digestive system.

8. Activates Manipura Chakra: In yogic philosophy, Nauli activates the Manipura (solar plexus) chakra, linked with strength, confidence and willpower. The bandhas used in Nauli also work with the Muladhara and Vishuddha chakras.

9. Increases the Flow of Prana: Nauli is believed to help prana (vital energy) flow smoothly through the body.

10. Strengthens Mental Focus: Nauli needs complete attention. Regular practice builds concentration and presence of mind.

11. Supports Other Cleansing Practices: Nauli is needed for Basti, the yogic colon cleanse, and strengthens the bandhas used in advanced pranayama.

Does Nauli Kriya Help with Weight Loss?

Nauli does not burn fat or reduce belly fat by itself. It supports digestion and core strength. As part of a healthy diet and an active routine, it can support a healthy weight.

Best Time to Practise Nauli Kriya

• According to yoga teachers, the best time to practise Nauli Kriya is early morning, when the stomach and bowels are completely empty.
• The bowels and bladder should be emptied before practice.
• If you have eaten a heavy meal, wait around 5–6 hours before practising.

Is Nauli Kriya Dangerous? Side Effects and Precautions

Is Nauli harmful? For healthy people who learn it slowly under a trained teacher, Nauli is generally safe. But practised wrongly, or by people with certain health conditions, it can cause problems. These are the main Nauli Kriya dangers to know.

Possible Side Effects

• Abdominal pain or cramps
• Dizziness or light-headedness from holding the breath too long
• Nausea, especially if practised after eating
• Strain in the lower back

Stop immediately if you feel any pain.

Who Should Avoid Nauli Kriya

• People with stomach or duodenal ulcers
• Women during menstruation
• Pregnant women, and women less than 3 months after delivery
• People with gallstones or kidney stones
• People with high blood pressure or heart disease
• People with a hernia, or anyone who has had recent abdominal surgery
• People with asthma or glaucoma, as the practice involves holding the breath out
• People with acute back pain, vertigo, migraine or frequent dizziness
• People who feel weak, unwell, or in pain anywhere in the body

Older adults should be careful and practise only a few gentle rounds, with a teacher’s guidance. People with anxiety or depression should practise only under a teacher’s supervision, as intense breath retention can sometimes increase unease.

Safety Tips

• Always practise on an empty stomach.
• Learn from a qualified yoga teacher, not only from videos.
• Don’t hold the breath beyond your comfort.
• If you have any medical condition, check with your doctor first.

Conclusion

Nauli Kriya is often called the crown of Hatha Yoga practices, and for good reason. It asks for patience, steady practice, and a strong foundation in the bandhas, but it rewards you with better digestion, deep core control, and a sharper, more focused mind. Start slowly with Uddiyana Bandha and Agnisara, respect your body’s limits, and let each stage come in its own time. It is an art we all can learn, but it must be practised with good care.

Because Nauli is an advanced kriya, it is best learned in person from an experienced teacher who can correct your technique and keep you safe. At Rishikul Yogshala, Nauli and the other Shatkarmas are taught as part of our Yoga Alliance–certified Yoga Teacher Training in Rishikesh, India, alongside asana, pranayama, meditation and yoga philosophy.
