The right way to chant Aum Namah Shivaya Sadhguru: The sound AUM is not to be uttered as Om. The way it is to be uttered is, open your mouth – “AAHH,” and as you slowly close your mouth it becomes “OOH,” and “MAA.” It is a natural happening. It is not something that you do. If you just open your mouth and exhale, it will become “AAHH.” As you close your mouth, it slowly becomes “OOH”, and when you close it, it becomes “MMM.” “AAHH,” “OOH,” and “MAA” are known as the fundamental sounds of existence. If you utter these 3 sounds together, what do you get? “AUM.” So we say “AUM” is the most fundamental mantra.
