The Divine Sound (Mantra) “OM” is actually pronounced by “merging” three individual sounds: AA + UU + MM. As you flow through AA (like AH), UU (like OO), and MM (like MM) you experience the mantra-sound fully and can see that it is basically the long version of “OM”. The yogis (most-achieved meditation masters) of the ancient Himalayas taught that AH represents the total sound of human speech when the mouth is fully open. They also taught that MM represents the total sound of human speech when the mouth is fully closed. So, transitioning from mouth-open to mouth-closed represents the complete span of human speech. Therefore, AUM/OM represents the totality of sound from a human being. Hence, this sound is complete and perfect.
