Bhastrikā — the bellows. Rapid and rhythmic breathing, active and vigorous, like the bellows of a blacksmith.

“Destroyer of great sins” — it has intense purifying power. It dramatically activates prāṇa and eliminates blockages.

It is a warming and activating prāṇāyāma. It generates internal heat and stimulates all systems. It should not be practiced in excess or by those with high blood pressure or heart problems without supervision.
