What is Bandha?
A bandha is a muscular lock used in haṭha yoga to seal and redirect prāṇa during breathwork and posture practice. The three principal forms are mūla bandha (root lock), uḍḍīyāna bandha (abdominal lock), and jālandhara bandha (throat lock). Described in the *Haṭha Yoga Pradīpikā* from the fifteenth century, they remain central to āsana, prāṇāyāma, and kriyā practice.
What the three locks do
A bandha is a sustained muscular contraction held for the duration of a breath, a series of breaths, or a postural sequence. The three principal locks are anatomically specific. Mūla bandha, the root lock, is a drawing-up of the pelvic floor and the perineum. It engages the muscular ring the clinical literature calls the levator ani complex. The instruction is to hold it lightly enough that it can be maintained across long breath cycles without losing the softness uḍḍīyāna requires. Uḍḍīyāna bandha, the upward-flying lock, is performed on a full exhalation with the breath held out. The abdominal wall draws up and back toward the spine, lifting the diaphragm into the thoracic cavity. This creates a marked vacuum in the abdomen. The texts treat the resulting pressure shift as the operative driver of kriyā and advanced prāṇāyāma. Jālandhara bandha, the throat lock, is a chin-to-chest seal that closes the upper aperture of the trunk during breath retention. The classical literature warns that without it, pressurised air rises into the head, where the inexperienced practitioner is most likely to cause harm. All three combined form mahā-bandha. The haṭha texts describe this as the seal under which gathered prāṇa can be directed along the suṣumnā of the subtle body toward the chakras the classical model places along the central axis.
Where the locks sit in the haṭha curriculum
The *Haṭha Yoga Pradīpikā* of Svātmārāma (fifteenth century) and the Gheraṇḍa Saṃhitā (seventeenth century) treat bandha as one of six categories of technique, alongside āsana, prāṇāyāma, mudrā and ṣaṭkarma. Both texts are notable for their caution. A bandha taken on without the preparatory āsana and prāṇāyāma base is, they argue, more likely to produce harm than benefit. The Pradīpikā devotes considerable space to contraindications. Contemporary studio practice has largely shed the bandhas along with longer breath retentions and deeper meditation work. What circulates in popular Vinyāsa flow under the heading of engaging mūla bandha is usually a much lighter engagement than the classical instruction describes. The Aṣṭāṅga Vinyāsa tradition codified by Pattabhi Jois is the main exception. There, mūla bandha and uḍḍīyāna bandha are held continuously throughout the vinyāsa, paired with the dṛṣṭi gaze-points and the ujjāyī breath as the three elements that distinguish the practice from a postural-only sequence. The Iyengar tradition is a second exception, teaching the bandhas with the same technical specificity that characterises its broader postural pedagogy.
Where to encounter them in the index
The most direct transmission of the bandhas in the corpus comes through Sadhguru, whose Śaiva yogic curriculum carries the haṭha system in a form closer to the classical original than most contemporary postural-yoga offerings. *Inner Engineering: A Yogi’s Guide to Joy* is the printed introduction. The Inner Engineering Online course transmits the Shambhavi mahāmudrā kriyā, a roughly twenty-one-minute seated sequence whose operative core is a bandha-mudrā configuration integrated with prāṇāyāma and a directed gaze. Sadhguru on disability and spiritual practice and Sadhguru on unlocking the mind’s full potential describe the same energetic mechanics without foregrounding the technical names. Paramahansa Yogananda’s *Autobiography of a Yogi* is the canonical Western entry into the kriyā lineage descended from Lahiri Mahasaya. The bandhas play a role in that technique, but the specific working configurations are preserved in the lineage’s initiated transmission rather than in print. Yogananda sketches the framework without disclosing the details, in keeping with the kriyā tradition’s reserve.
What bandhas are not
The bandhas are not an isometric core-strength exercise. The contemporary fitness-yoga rendering of mūla bandha as a kegel-equivalent pelvic-floor strengthener captures part of the physical mechanics and misses the rest. In the classical texts the locks are sustained inside breath-controlled practice because the operative claim is on prāṇa movement, not muscular conditioning. The muscular engagement is the means, not the end. They are also not a standalone practice that can be lifted out of the haṭha curriculum and dropped into an unprepared regimen. The texts are explicit: bandha without the prior āsana and prāṇāyāma foundation is the most common cause of the energetic dysregulation the classical literature warns about. The Pradīpikā and the Gheraṇḍa Saṃhitā treat the bandhas as gates inside the practice, not exercises done for their own sake. They organise where the energy gathered by the breathwork is allowed to go, opened in deliberate sequences and closed when the work is complete.
