In Sanskrit Bhastrika means 'bellows'. Rapid succession of forcible expulsion is a characteristic feature of Bhastrika. Just as a blacksmith blows his bellows rapidly, so also you should move your breath rapidly.
Sit on Padmasana. Keep the body, neck and head erect. Close the mouth. Next, inhale and exhale quickly ten times like the bellows of the blacksmith. Constantly dilate and contract. When you practise this Pranayama a hissing sound is produced. The practitioner should start with rapid expulsions of breath following one another in rapid succession. When the required number of expulsions, say ten for a round, is finished, the final expulsion is followed by a deepest possible inhalation. The breath is suspended as long as it could be done with comfort. Then deepest possible exhalation completes one round of Bhastrika. Rest a while after one round is over by taking a few normal breaths. This will give you relief and make you fit for starting the second round. Do three rounds daily in the morning. You can do another three rounds in the evening also. Busy people who find it difficult to do three rounds of Bhastrika can do one round at least. This also will keep them quite fit.
Bhastrika is a powerful exercise. A combination of Kapalabhati and Ujjayi makes up Bhastrika. Practise Kapalabhati and Ujjayi to start with. Then you will find it easy to do Bhastrika.
Some prolong the practice till they get tired. You will get perspiration profusely. If you experience any giddiness stop the practice and take a few normal breaths. Continue the practice after the giddiness has vanished. Bhastrika can be done both in the morning and evening in winter. In summer do it in the morning only during cool hours.
Bhastrika relieves inflammation of the throat, increases gastric fire, destroys phlegm, removes diseases of the nose and chest and eradicates asthma, consumption, etc. It gives good appetite. It breaks the three Granthis or knots viz., Brahma Granthi, Vishnu Granthi and Rudra Granthi. It destroys phlegm which is the bolt or obstacle to the door at the mouth of Brahma Nadi (Sushumna). It enables one to know the Kundalini. It removes all diseases which arise from excess of wind, bile and phlegm. It gives warmth to the body. When you have no sufficient warm clothing in a cool region to protect yourself from cold, practise this Pranayama and you will get sufficient warmth in the body quickly. It purifies the Nadis considerably. It is the most beneficial of all Kumbhakas. Bhastrika Kumbhaka should be specially practised as it enables the Prana to break through the three Granthis or knots that are firmly located in the Sushumna. It awakens the Kundalini quickly. The practitioner will never suffer from any disease. He will always be healthy.
The number of exhalations or rounds is determined by the strength and capacity of the practitioner. You must not go to extremes. Some students do six rounds. Some do twelve also.
You can practise Bhastrika in the following manner. There is some slight change in the end. Having inhaled and exhaled quickly twenty times, inhale through the right nostril, retain the breath as long as you can do it comfortably and then exhale through the left nostril. Then inhale through the left nostril, retain the breath as before and then exhale through the right nostril.
Repeat OM mentally with Bhava and meaning throughout the practice.
There are some varieties of Bhastrika wherein one nostril only is used for breathing purposes and in another variety the alternate nostrils are used for inhalation and exhalation.
Those who wish to do Bhastrika for a long time in an intense manner should live on Kichadi, and take an enema or do Bhasti in the morning before starting the practice.
