Bhramari is a relaxing technique.
The word Bhramar means “bee” in Sanskrit. So, here the practitioner creates the same deep, low pitched humming sound as that of the black bee. It is used in nada yoga to awaken awareness of the inner psychic sounds.
According to Hatha Yoga Pradipika (sutra 68), the definition of bhramari is:
"Inhale producing louder imitating the sound of a male wasp and exhale slowly producing sound of low tune of a female wasp. Practicing in this way a peculiar type of blissful experience is produced in the mind of best yogis."
Bhramari pranayama is differently described in Gheranda Samhita: there, this pranayama is meant for listening to the internal sound known as Anahat nada. And it has been also considered as a means for Samadhi.
Relieves stress, anger, anxiety and insomnia.
Creates a soothing effect on the mind and nervous system.
Very good technique to enhancing the memory and the concentration.
It induces a meditative state.
It makes the practitioner introvert.
People suffering from severe ear infections or severe ear pains should not practice this pranayama.
Depressed people should not practice too much because this technique makes the practitioner more introvert.
