To be specific, during Bhramari exercise, the practitioner while trying the task of imitating snoring and also observe the movement of the soft palate in his mind. Actually the soft palate is being lifted and then drawn towards the nasal part of the throat. This movement can actually be felt inside the mouth. Then drawing the soft palate a bit closer to the throat, he needs to breathe in air.
A beautiful sound is thus created by this mishmash of gentle vibrations of the 'soft palate'. Then the nasal friction will also be heard. Although in the initial stage it seems to be very difficult for an exerciser to adept this process. However, with vigorous practice one can do it easily and smoothly. So much so that Bhramari expert can even produce such melodious sound which to a listener it seems as if it is the sound has been produced from a string instrument. Some Yoga scholars claim that serene sound produced by this Bhramari asana can give the feel of divine bliss to any of the diligent exerciser.
