Shatkarma: The 6 Yogic Cleansing Practices

The shatkarmas — from shat (six) and karma (action or practice) — are the six purification practices of Hatha Yoga, described in detail in the Hatha Yoga Pradipika. Unlike the asanas and pranayamas, which are primarily practices of development, the shatkarmas are practices of cleansing — specifically designed to remove the impurities and blockages in the physical body that prevent pranayama and higher meditation practices from working effectively. They are not supplementary techniques; the classical texts present them as prerequisites for serious pranayama work.

Why Purification Comes First

The Hatha Yoga Pradipika presents the shatkarmas in the context of nadishodhana — purification of the pranic channels (nadis). When the body accumulates mucus, toxins, and energetic obstruction in the digestive tract, respiratory system, and sense organs, pranayama practices cannot circulate prana effectively through the blocked channels. The shatkarmas clear these blockages so that pranayama and subsequent practices can work at full depth. This sequence — purification before development — is logical and reflects an understanding of the relationship between physical cleanliness and pranic clarity.

The Six Practices

1. Neti — Nasal Cleansing

Neti has two forms. Jala Neti (water nasal cleansing): warm saline water is poured through one nostril using a neti pot and flows out the other. This clears the nasal passages of excess mucus, allergens, and debris; reduces sinus congestion; and prepares the nasal passages for optimal pranayama practice. Sutra Neti (thread nasal cleansing): a waxed cotton thread is passed through the nostril and out through the mouth, then drawn back and forth to mechanically cleanse the nasal passage. More advanced and requiring expert instruction.

2. Dhauti — Digestive Tract Cleansing

The most important Dhauti practice is Vaman Dhauti (also called Kunjal Kriya) — drinking 4–6 glasses of warm saline water on an empty stomach, then regurgitating it through deliberate stimulation of the gag reflex. This cleanses the stomach of excess acid, mucus, and undigested material. Particularly recommended for those with hyperacidity, nausea, or early morning heaviness. Requires proper instruction and should not be performed more than once weekly.

3. Nauli — Abdominal Churning

Nauli is considered the most powerful of the shatkarmas. It involves isolating and rotating the rectus abdominis muscles in a churning action, massaging the abdominal organs. The precondition is mastery of Uddiyana Bandha. Nauli stimulates all the digestive organs (liver, spleen, pancreas, intestines), strengthens the abdominal muscles, and is said to be the most effective internal massage available to a yoga practitioner. Requires expert instruction — incorrect practice can cause abdominal strain.

4. Basti — Colon Cleansing

The yogic version of an enema — drawing water into the colon through the anus using the muscle control developed in Nauli and Ashwini Mudra. Traditionally performed while immersed to the navel in water. Particularly effective for chronic constipation and for the deep cleansing preparation that precedes Panchakarma or extended meditation retreats.

5. Trataka — Concentrated Gazing

Fixed, unblinking gaze at a single point — traditionally a ghee lamp flame — until tears flow. This practice simultaneously cleanses the eyes (the tear reflex flushes the lacrimal ducts), strengthens the extraocular muscles, and develops concentration to a degree that dramatically accelerates meditation progress. It is the most accessible of the shatkarmas and the one most widely applicable without advanced preparation.

6. Kapalabhati — Skull-Shining Breath

Rapid diaphragmatic pumping through forceful exhalations — described in detail in the pranayama section. As a shatkarma, its function is specifically purification of the respiratory tract and nasal passages. The forced exhalations expel the stale air from the lower lung lobes that passive breathing never reaches. Practised as shatkarma, it precedes the pranayama sequence as a cleansing preparation.

Learning the Shatkarmas

Jala Neti and Trataka can be learned from written instruction with reasonable safety. Vaman Dhauti, Nauli, and Basti require in-person instruction from a qualified teacher to learn correct technique. The Medhya Laya 200 Hour TTC includes practical instruction in Jala Neti, Trataka, and Kapalabhati (as shatkarma), with an introduction to Vaman Dhauti and the theory of Nauli and Basti.
