Nauli 101: How To Purify The Body Using This Ancient Yoga Technique
Many yoga classes taught the West focus on the physical postures (also known as the asanas), with a little breathwork (pranayama) thrown in. If you've mastered your crow, feel happy in lotus, and are craving something new, it might be time to explore the kriyas—lesser-known parts of the yogic discipline that focus on ritual purification techniques. These internal cleansing practices have been used for thousands of years, and one of the most popular is Nauli Kriya.
What is Nauli Kriya, and how do you practice it?
For yogis, being internally cleansed is essential for mental, physical, and spiritual focus and strength. Nauli is a preliminary cleansing exercise that involves isolating muscles in the abdominal area and sucking them inside the rib cage. Its origins lie in the Sanskrit roots nau ("boat") and li ("to cling to"), and, when done correctly, the practice creates a wave motion in the abdominal area.
Here's how it's done: First and foremost, always practice Nauli on an empty stomach, preferably first thing in the morning after you use the bathroom. Do not eat or drink anything, even water, beforehand as it will make the motion uncomfortable.
There are five steps of the Nauli Kriya. It's best to practice each one repeatedly before going on to the next if you're a beginner. This ensures you will be able to do the full technique correctly.
Step 1: Bahya Uddiyana Bandha
From standing, place your hands on your thighs, bend your knees, and exhale all the air out of the lungs and pause. Relax the belly, but don't inhale. Swallow, and when you feel the throat muscles tighten, hold. With the mouth closed and throat contracted, imagine you're taking a big inhale. No air will come in, but the pressure created by your diaphragm trying to draw air into the lungs will cause your abdominal contents to be hollowed out.
Step 2: Agnisara Kriya
Now you'll create a wavelike motion with the abdominal muscles by engaging and releasing Uddiyana Bandha. Without inhaling or exhaling, slowly release the fake inhalation. And then again, without inhaling/exhaling, reestablish full uddiyana bandha.
Step 3: Madhyama (Middle) Nauli
Maintain the hollow created with uddiyana bandha in Step 1, and use the pressure of your hands against your thighs to push out the abdominal muscles. The sides of your belly will be sucked back in by the vacuum, and the rectus will protrude.
Stage 4: Vama (Left) and Dakshina (Right) Nauli
This one takes quite a bit of practice: If you've achieved Step 3, you can now work on isolating the left and right sides of the abdominals. From Step 3, release the weight from your right hand so that you are pushing down strongly into only your left thigh. This should make the right side of the abdomen retreat and the left side protrude (a shape known as vama nauli). Then, repeat on the other side: Release the left hand so that weight is only in the right (known as dakshina nauli).
Stage 5: Nauli Kriya
This is it! If you can practice each stage successfully, then you're ready for full Nauli, which essentially strings together Steps 1 through 4 to form a continuous motion. From Step 3, go to vama nauli in Step 4, then back to Step 1, then to dakshina nauli in Step 4, then back to Step 3. Release, inhale, and return to standing when you feel you are at your capacity.

Benefits of Nauli
Nauli is thought to stimulate the body's digestive fire, also known as agni. By fueling this fire, the practice can be beneficial for digestion. Nauli is essentially an internalized form of an abdominal massage, which is known to stimulate and regulate digestion too.
A stronger core
Nauli kriya is a powerful abdominal workout that requires core strength and the ability to isolate the muscles of the rectus abdominis, which make up the "six-pack," or "washboard" region of the abs. Practicing it properly and employing these muscles regularly will strengthen and tone them.
Healthier internal organs
Proponents of the practice believe that the churning effect of Nauli massages the internal organs (such as the stomach, liver, spleen, urinary bladder, pancreas, gallbladder, and large and small intestine) and helps the body eliminate toxins in the digestive tract, though evidence of this is largely anecdotal.
Increased mental clarity
Some people believe that because Nauli kriya stimulates the solar plexus or manipura chakra (a storehouse of prana, or energy), it increases mental clarity and reduces brain fog. Again, evidence of this is anecdotal and hasn't been backed up by research.
While some of the benefits claimed of Nauli are not yet scientifically proven, many practitioners nonetheless enjoy this challenging and advanced purification technique.
Is Nauli dangerous?
Nauli may look unnatural and intimidating, but it is safe for most people. However, since it's an advanced yoga practice, it's best tried for the first time under the supervision of an experienced yoga teacher. There are also a few instances whe/n you should not practice Nauli, including if you're pregnant or trying to become pregnant; have any symptoms of constipation, diarrhea, or heartburn/acid reflux; have hernias; or are suffering from heart problems, since the practice raises heart rate significantly. If you're unsure whether it's for you, it's always best to consult an experienced yoga teacher as well as your medical doctor before attempting Nauli.
If Nauli isn't right for you, another rewarding and more accessible yogic cleansing practice is Ujjai breathwork, and if you're looking for something a little calmer, this timed breathwork routine is perfect.
