This Ghosha, known by the name Pranav, is not pronounced through external efforts. It is not even a consonant and a vowel. It is not pronounced even through throat, palate, lips or nose etc. It is also not pronounced from the area called teeth situated at the end of both the lips. ‘Pranav’ is the best letter, which never disappears. Omkar should be practiced in the form of Pranayama and the mind should always be engaged in the resonating sound.
