Duration/repetitions: Beginners may practice Bhramari three times and advanced practitioners for 11-21 times.
Technique: Breathe in and out with the nose only. Close the ears with your thumbs, place index fingers just above the eyebrows at the sinuses and the remaining three fingers on the eyes with finger tips slightly pressing the ridge of the nose on each side. Inhale deeply and while exhaling make a humming sound like that of the black beetle. Say "Om' in a soft humming sound while making the humming sound.
Mental focus: Concentrating on the center of the eyebrows (ajna chakra) visualize light in the center. Feel that your body, mind and soul are radiating with light. Try to experience inner joy and bliss.
Benefits: Good for sinus problem, hypertension, heart blockage, etc. Vibrations created by humming destroys negative energy, reduces stress/tension, depression, fears and doubts.
it is better to do soft humming that gently reverberates in the sinuses and the skull rather than powerful vibration. Four to five repetitions of Bhramari is plenty. People with epilepsy, head trauma or tumor, migraine, severe or persistent headaches should avoid Bhram
