Aum is often called the "sound of the universe". Sounds hippy-dippy, yes...but the vibration that resonates in your body when you chant has both physical and physiological benefits! It can bring a sense of calm and focus, it can decrease blood pressure, increase relaxation, and the vibration can give a little massage to your chest, throat and head.
There are actually three different sounds that are made when you chant OM...the first is "Aaahhh", and the vibration begins at the heart. From there, it moves to the "Ooohhh" sound (like "home") which resonates in our throat. The final sound, "Mmmm" has a sound that can be felt in our head. You can even put your palm on each body part when you make the sound to feel it!
