You can watch the video in my YouTube channel "Transform Your Life with coach Nalini". Link is also given in the podcast description. This is recorded live in Group meditation. How to chant AUM? The root sounds are "Aa", "Oo" and "Mm", uttered together as "Aum".
Say Aaa from beneath the naval, from manipura chakra.
Then gently close your mouth by saying Uuuuu and mmmmm.
All three sounds should be utetred for equal duration.
The mantra activates and energizes the various sections of the body, reverberating through the whole system. Furthermore, it can bring peace and balance to the meditator's system, and is known to relieve people from numerous physical and mental ailments when practiced regularly.
