Shat Karma Kriyas: The Six Purificatory Actions of Yoga
Imagine you are about to clean a house that has been locked for years. You wouldn't start by arranging the furniture — you would first sweep out the dust, clear the cobwebs, and wash the floors. The Shat Karma Kriyas are exactly that for the human body and mind. They are the six classical yogic purification techniques designed to remove physical and energetic blockages before deeper practices like pranayama and meditation can be safely and effectively undertaken.
The word Shat means six, and Karma means action. These are not exercises in the modern sense — they are deliberate, often intense, cleansing procedures. Their purpose is not to build strength or flexibility, but to create a clean, stable vessel for the energy (prana) to flow freely.
The Six Kriyas
The six techniques are traditionally grouped as follows:
| Kriya | Meaning | Primary Action |
|---|
| Dhauti | Washing | Cleansing the digestive tract (stomach, esophagus, intestines) |
| Basti | Enema | Cleansing the colon |
| Neti | Nasal cleansing | Clearing the nasal passages |
| Trataka | Gazing | Concentrated staring to purify the eyes and mind |
| Nauli | Churning | Abdominal churning to massage internal organs |
| Kapalabhati | Skull-shining | Rapid, forceful exhalations to cleanse the frontal sinuses and lungs |
These are advanced practices. Never attempt them without direct guidance from a qualified teacher. Improper technique — especially with Dhauti, Basti, or Nauli — can cause injury.
Why Purification First?
The classical yogic texts, particularly the Hatha Yoga Pradipika, state that purification must precede all other practices. The reasoning is simple: if the body is clogged with toxins, mucus, or undigested food, prana cannot move freely. Pranayama on a congested system can create imbalance, even harm. The Shat Karmas clear the physical channels (nadis) so that energy work becomes safe and fruitful.
A Closer Look at Each Kriya
Dhauti — The most well-known form is Vamana Dhauti (also called Kunjal Kriya), where you drink several glasses of lukewarm salted water and then voluntarily vomit it back out. This washes the stomach and esophagus. Another form, Vastra Dhauti, involves swallowing a long strip of cloth and then pulling it out — this is extremely advanced and should never be attempted alone.
Basti — This is yogic enema, but unlike a medical enema, it uses the abdominal muscles to draw water into the colon and then expel it. It cleanses the large intestine and is said to balance the Apana Vayu (the downward-moving energy).
Neti — Jala Neti uses a small pot to pour warm saline water through one nostril and out the other. Sutra Neti involves threading a soft catheter through the nose and out the mouth. Neti clears the sinuses, improves breathing, and is often recommended before pranayama.
Trataka — You sit still and gaze without blinking at a fixed point — traditionally a candle flame. When tears come, you close your eyes and visualise the flame at the eyebrow centre. This strengthens the eyes, improves concentration, and calms the mind.
Nauli — After mastering Uddiyana Bandha (abdominal lock), you isolate and rotate the rectus abdominis muscles in a churning motion. This massages the digestive organs, stimulates peristalsis, and is considered one of the most powerful kriyas.
Kapalabhati — Often mistaken for a breathing exercise, this is a kriya. You exhale forcefully and rapidly through the nose (about one breath per second) while the inhalation happens passively. The focus is entirely on the exhalation. It cleanses the lungs, sinuses, and energises the brain. …
