Bhastrikā

Bhastrikā (भस्त्रिका) is an intense prāṇāyāma technique characterized by forceful, rapid inhalations and exhalations of equal duration, powered by the diaphragm and accompanied by an audible sound. The name means “bellows,” likening the practitioner’s lungs to the blacksmith’s bellows that stoke a fire. The Hatha Yoga Pradīpikā commends its plentiful practice, saying that it quickly breaks the three knots (granthi) and awakens the kuṇḍalinī.

Bhastrikā is considered more vigorous than kapālabhātī — B.K.S. Iyengar described kapālabhātī as “a milder form of Bhastrikā” — involving active and forceful movements in both directions of breath. It is traditionally said to generate internal heat (tapas) and awaken the kuṇḍalinī energy.

Origins

The practice appears in the Hatha Yoga Pradīpikā (2.59–2.63), where it is described as a powerful method to destroy energy blockages and purify the nāḍīs (energy channels). The Shiva Saṃhitā also mentions it as a means to achieve control over the vital breath. In traditional sequencing, it is often taught after kapālabhātī, building on the purification achieved by that practice. The Gheraṇḍa Saṃhitā places it among the advanced prāṇāyāma techniques.

Technique

The practitioner sits erect and breathes rapidly through the nose, with forceful, equal-duration inhalations and exhalations — one inhalation and one exhalation forming a single round. Unlike kapālabhātī, where only exhalation is active, bhastrikā employs active effort in both phases. The Hatha Yoga Pradīpikā describes the breath moving with the rapid, hissing action of a bellows.

Typically, 20–30 breaths constitute one round, with the practitioner pausing after each round to observe the effects. Three to five rounds are traditionally recommended.

Benefits (as claimed by tradition)

Traditional texts claim Bhastrikā:

• Intensely purifies the nāḍīs (energy channels)
• Generates internal heat and kindles the digestive fire
• Destroys energy blockages (granthi)
• Awakens kuṇḍalinī shakti
• Balances the three doṣas and increases vitality

The Hatha Yoga Pradīpikā states that it “destroys diseases of the nāḍīs” and brings about prāṇic awakening.

In modern practice

Bhastrikā is considered an advanced practice and is often taught only to experienced students. It is valued for its stimulating and energizing effects, and is sometimes used as a pratyāhāra (sense withdrawal) preparation. Physiological studies suggest it increases oxygen consumption, metabolic rate, and sympathetic nervous system activation. It should be avoided by those with hypertension, heart conditions, or during pregnancy.
