This module teaches the pa-varg: प फ ब भ म. These sounds are made with the lips, so focus on lip closure, voicing, and aspiration.
Learn to recognize प फ ब भ म. Because these are lip sounds, connect what you see with how the lips move when you say them.
Say each example clearly. These letters all begin with lip closure, so pay attention to whether the sound is voiced, aspirated, or nasal.
