Maha Bandha (Great Lock)

Mahā means "great," and Bandha means "lock" or "seal." Mahā Bandha is the simultaneous engagement of all three major Bandhas — Mūla Bandha (Root Lock), Uḍḍīyāna Bandha (Abdominal Lock), and Jālandhara Bandha (Chin Lock) — creating a unified seal throughout the entire length of the torso.

Mahā Bandha is considered the pinnacle of Bandha practice in the Hatha Yoga tradition. When all three locks are engaged together, Prāṇa is prevented from dissipating through the body's extremities and is instead drawn powerfully into the Suṣumṇā Nāḍī (central energy channel). Classical texts describe this as one of the most potent techniques for purifying the nāḍīs, awakening Kuṇḍalinī energy, and accelerating the movement toward Samādhi.

Mahā Bandha is practiced during Kumbhaka (breath retention), typically on the external retention after a full exhalation. The sequence is precise: exhale completely, engage Mūla Bandha at the pelvic floor, draw Uḍḍīyāna Bandha upward behind the navel, then lower the chin for Jālandhara Bandha. Hold for as long as comfortable, then release in reverse order — Jālandhara first, then Uḍḍīyāna, then Mūla — before inhaling. Repetitions are built gradually over months of consistent practice. This is an advanced technique; students must have established mastery of each individual Bandha before attempting the combined form.
