The word 'Bhramari' is derived from Hindi 'Bhramari' which means bee. In this Pranayama, the buzzing sound of a Bhramar is produced while doing Rechaka.
Sit in Jnan Mudra and normalise your breath. Close both ears with your index fingers keeping the palms of the hands open and the elbows on level with the shoulders. Inhale slowly and fill your lungs with air. Now do Antrik Kumbhaka for a few seconds and exhale slowly producing the buzzing sound of a Bhramar. After this, do Bahya Kumbhaka for two seconds and repeat this activity. In this way, do it for five to seven times. Its frequency can be increased gradually. The rhythm of buzzing should not discontinue.
Bhramari Pranayama is in fact a spiritual exercise. By its long practice, one achieves the Siddhi or Nad Bramha.
In several physical disorders also it shows its effect. It helps relieve the tension of mind and keeps the mind alert. It also strengthens the veins and tissues of the brain and provides massage for them. It helps in the awakening of the Ajna Chakra.
