Bandhas and Pranayama: The Yogic Locks Explained

By Breathwork Studios · Updated March 2026 · 9 min read

Bandha (Sanskrit: bond, lock, seal) refers to specific muscular contractions applied during pranayama to direct and contain prana — sealing it within the body's central channel and intensifying its effects. The Hatha Yoga Pradipika describes bandhas as essential companions to kumbhaka (breath retention), stating that pranayama without the appropriate locks is like building a fire without containing it.

There are three primary bandhas — Jalandhara, Mula, and Uddiyana — and a fourth that combines all three simultaneously: Maha Bandha. Each works on a different region of the body and governs a different aspect of pranic movement.

Jalandhara Bandha — The Chin Lock

Name: Jalandhara (jala = network/web, dhara = upward flow or holding) — the lock that holds the network of nadis in the throat.

Action: The chin is drawn down and back toward the sternum — not simply dropped forward but actively pressed inward. The sternum simultaneously lifts slightly toward the chin. The throat is sealed.

When applied: During Antara Kumbhaka (full breath retention, after inhale). The lock is released before the exhalation begins.

What Jalandhara Bandha does

Physiologically: The chin pressing against the sternum directly compresses the carotid sinus — a cluster of baroreceptors in the carotid artery at the base of the throat. Baroreceptor stimulation sends signals to the brainstem that interpret high blood pressure, triggering a strong parasympathetic response: slowed heart rate, reduced blood pressure, and deep calm. This is one of the most direct vagal stimulation pathways available in pranayama practice.

Pranic framework: Jalandhara seals the throat, preventing Udana vayu (upward-moving prana) from escaping during retention. It also contains the prana that accumulates during Antara Kumbhaka, directing it downward into the body's central channel rather than allowing it to dissipate through the throat and head.

Traditional source: The Hatha Yoga Pradipika (Chapter 3, verse 70–72) describes Jalandhara as destroying all diseases of the throat and preventing old age. It states that by contracting the throat and holding the chin firmly against the chest, the nectar (amrita) that flows from the Sahasrara is prevented from being "consumed by the fire" of the digestive region.

How to practice Jalandhara Bandha

1. Take a full inhalation and retain the breath.
2. Lower the chin toward the chest — simultaneously lift the sternum slightly toward the chin.
3. Maintain the lock comfortably throughout the retention.
4. Before exhaling: lift the chin first, then release the breath slowly.
5. Never exhale with the chin lock still applied — always release the lock first.

Contraindications

Cervical spine injury or degeneration, high intracranial pressure, hyperthyroidism. Caution with hypertension (the initial baroreceptor stimulation briefly raises pressure before the vagal response lowers it).

Mula Bandha — The Root Lock

Name: Mula (Sanskrit: root, base, foundation). The lock of the root centre.

Action: A gentle contraction of the perineum and pelvic floor — the muscles between the pubic bone and the coccyx. In women this corresponds roughly to a Kegel contraction; in men, a similar perineal contraction. The contraction is subtle — not a gross clenching of the buttocks or inner thighs, but a specific internal lift at the pelvic floor.

When applied: During both Antara Kumbhaka (full retention) and Bahya Kumbhaka (empty retention). Also used continuously during certain pranayama sequences in advanced practice.

What Mula Bandha does

Physiologically: The pelvic floor contraction activates the deep core — the same system engaged in diaphragmatic breathing (diaphragm, pelvic floor, transversus abdominis work together for spinal stability). Mula Bandha coordinates this system and activates the pudendal nerve, which has connections to the sacral parasympathetic outflow. The subtle upward lift of the pelvic floor may also stimulate the inferior hypogastric plexus, part of the autonomic nervous system's pelvic ganglion network.

Pranic framework: Mula Bandha seals the base of the body, preventing Apana vayu (downward-moving prana) from escaping downward. By containing Apana at the root, it allows Apana to be directed upward to meet Prana vayu at the navel — a meeting described in classical texts as creating the inner fire (agni) that purifies and energises the entire system.

Traditional source: The Hatha Yoga Pradipika (Chapter 3, verse 61–68) describes Mula Bandha as unifying Prana and Apana, eliminating urinary and digestive ailments, and as "the best of all bandhas." The Gheranda Samhita states that it prevents the aging process and makes one appear young.

How to practice Mula Bandha

1. Find the perineum — the area between the genitals and the anus.
2. Practice the contraction first without breath retention: inhale, and on the exhale, gently lift and contract the perineum inward and upward. Release on the next inhale.
3. Once comfortable, apply during breath retention: retain the breath and apply the perineal lift and contraction. Maintain throughout the hold.
4. Release the lock before releasing the breath.

Contraindications

Pelvic inflammatory disease, recent pelvic or abdominal surgery, pregnancy. Avoid during menstruation (traditional caution).

Uddiyana Bandha — The Upward Lock

Name: Uddiyana (Sanskrit: upward flight). The lock of the upward-flying prana.

Action: After a complete exhalation with the lungs empty, the diaphragm is lifted and the abdominal wall is drawn sharply inward and upward — creating a dramatic abdominal vacuum. The false inhalation — expanding the ribcage without actually breathing in — creates the negative pressure that draws the abdominal organs up into the thoracic cavity.

When applied: Exclusively during Bahya Kumbhaka (empty breath retention, after exhalation). Never attempted with air in the lungs.

What Uddiyana Bandha does

Physiologically: The abdominal vacuum created by Uddiyana Bandha produces the most vigorous internal massage of the abdominal organs of any yogic practice — the liver, spleen, pancreas, stomach, and intestines are all compressed and then released. This stimulates digestive function, peristalsis, and lymphatic drainage from the abdominal region. The diaphragm's upward lift also directly massages the heart from below.

Pranic framework: Uddiyana locks Apana vayu into the upward direction, joining it with Prana vayu and directing the combined force into Sushumna. The name — "upward flight" — describes this lifting of the pranic energy toward the upper body and beyond.

Traditional source: The Hatha Yoga Pradipika (Chapter 3, verse 55–60) describes Uddiyana Bandha as the "lion that kills the elephant of death" — a hyperbolic description of its supposed life-extending effects. It calls Uddiyana "the best of bandhas" and states that one who practices it will appear young even in old age.

How to practice Uddiyana Bandha

1. Stand with feet shoulder-width apart, hands on thighs.
2. Take a full inhalation, then exhale completely — emptying the lungs fully.
3. With the lungs empty, expand the ribcage as if about to inhale (false inhalation) without actually breathing in. Feel the diaphragm lift and the abdominal wall draw sharply inward and upward.
4. Hold for 3–10 seconds (increase gradually). The abdomen should be hollow.
5. Release the lock gently before inhaling. The release should be gradual, not abrupt.
6. Never practice Uddiyana Bandha with air in the lungs.

Contraindications

Pregnancy, hernia (hiatal or abdominal), ulcers, high blood pressure (the pressure changes during the lock can be significant), heart conditions, recent abdominal surgery, and during menstruation.

Maha Bandha — The Great Lock

Name: Maha (Sanskrit: great). The great lock that combines all three.

Action: All three bandhas applied simultaneously during breath retention — Jalandhara (chin lock), Mula Bandha (root lock), and Uddiyana Bandha (abdominal lock).

What Maha Bandha does

Maha Bandha seals the body at three points simultaneously — top (throat), bottom (perineum), and middle (abdomen) — creating a complete containment of prana during retention. In the pranic framework, this is the most complete possible sealing of prana within the central channel. The Hatha Yoga Pradipika describes Maha Bandha as giving all the benefits of the three individual bandhas together and as capable of overcoming death — the tradition's way of describing its most powerful life-extending effects.

Maha Bandha is the technique that corresponds to the "Yogi" level in Yogi Breath's six-level curriculum — the most advanced practice in the pranayama system.

Applying Maha Bandha

1. Take a full inhalation.
2. Apply Jalandhara Bandha (chin to chest).
3. Apply Mula Bandha (perineal contraction).
4. For the full Maha Bandha: exhale, then apply Uddiyana Bandha (abdominal vacuum) with the lungs empty, while maintaining Jalandhara and Mula.
5. Hold for a comfortable duration.
6. Release Uddiyana first, then Jalandhara, then Mula. Inhale slowly.
