Bandha

Bandha literally means “lock,” “bond,” or “restraint” in Sanskrit, referring to specific muscular engagements that seal and redirect the flow of prāṇa (vital energy) within the body. In the hatha yoga system, bandhas are considered essential companion practices to āsana, prāṇāyāma, and mudrā. They function as energetic valves that prevent prāṇa from dissipating through the lower gateways of the body and instead channel it upward through the central channel (suṣumnā) toward the higher cakras.

The three principal bandhas are mūla bandha (root lock), uddīyāna bandha (abdominal lock), and jālandhara bandha (chin lock). When all three are engaged simultaneously, the practice is called mahābandha (the great lock). Mūla bandha involves the contraction of the pelvic floor muscles, particularly the perineum in men and the cervix in women, and is said to prevent the downward escape of prāṇa and the vital essence (bindu). Uddīyāna bandha entails drawing the abdomen inward and upward beneath the diaphragm, creating a vacuum that massages the internal organs and directs prāṇa upward. Jālandhara bandha involves pressing the chin toward the sternum, closing the throat to prevent prāṇa from escaping through the upper gates.

Bandhas are traditionally practiced in conjunction with prāṇāyāma, particularly during kumbhaka (breath retention). During inhalation, mūla bandha is engaged; during retention, jālandhara bandha is added; and uddīyāna bandha is applied with the breath held out after complete exhalation. The Hatha Yoga Pradīpikā describes bandhas as the means by which kuṇḍalinī is awakened and directed upward. Without bandhas, the energy generated through prāṇāyāma and kuṇḍalinī practices cannot be properly contained and directed.

Origins

The concept of bandhas appears in early tantric texts, where they were described as energetic seals used in kuṇḍalinī yoga. The Hatha Yoga Pradīpikā (15th century CE) by Svātmārāma provides the most systematic treatment, devoting an entire section to the three bandhas and their integration with prāṇāyāma. The Gheraṇḍa Saṃhitā (17th–18th century CE) similarly describes the bandhas among the twenty-five mudrās as part of the broader hatha yoga curriculum. The Śiva Saṃhitā also discusses bandhas in the context of the subtle body and kuṇḍalinī awakening.

Technique

Mūla bandha is performed by drawing the perineum (or cervix) upward and inward, as if trying to lift the pelvic floor. The practitioner typically begins by isolating this contraction from the gluteal and abdominal muscles, gradually developing the ability to sustain it for extended periods. Uddīyāna bandha is practiced standing with the knees slightly bent, or seated, by exhaling completely, drawing the abdomen inward and upward under the ribcage, and holding the lock as long as comfortable. Jālandhara bandha is achieved by pressing the chin firmly against the manubrium (upper breastbone) while keeping the spine erect.

The Hatha Yoga Pradīpikā (3.13–3.19) provides detailed instructions for mahābandha, in which all three locks are engaged simultaneously. The practitioner sits in siddhāsana, engages mūla bandha, then jālandhara bandha, and finally uddīyāna bandha, holding the breath and the locks together. This combined practice is said to awaken kuṇḍalinī and send it coursing upward through the suṣumnā.

Benefits (as claimed by tradition)

According to traditional sources, bandhas prevent the loss of vital energy and direct it toward spiritual awakening. The Hatha Yoga Pradīpikā (3.61–3.69) describes mūla bandha, which prevents the descent of apāna (downward-moving prāṇa) and unites it with prāṇa (upward-moving prāṇa), generating a fire that awakens kuṇḍalinī. Uddīyāna bandha is said to make the body light and youthful, strengthen digestion, and activate the nāḍīs. Jālandhara bandha prevents prāṇa from escaping through the throat and directs it downward into the suṣumnā. The texts also claim that regular bandha practice removes diseases of the abdomen, purifies the blood, and stimulates the lymphatic system.

In modern practice

Bandhas are taught in traditional lineages of hatha yoga, including Iyengar, Ashtanga, and Kundalini yoga, though their presentation varies. In Ashtanga yoga, uddīyāna bandha and mūla bandha are emphasized during vinyāsa (breath-synchronized movement). In Kundalini yoga, bandhas are combined with specific kriyā (exercise sets) and breathing techniques. Scientific research on bandhas is limited, though studies on intra-abdominal pressure and diaphragmatic function suggest that uddīyāna bandha may have measurable effects on core stability and respiratory function.
