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. 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 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.
