The “Resonance of Being” can be thought of as the Om Vibration, as referred to in Yogic tradition. The vocalizing of the sound of Om, when toned with the back of the throat wide open (as in Tibetan low-voice chanting), the entire body, especially from the crown of the head to the base of the spine, begins to vibrate in resonance with the vocalized sound.
When the body vibrates in this particular way, it draws the mind deeply within, offering an easy entryway to the sublime experience of the subtle realms. Now, the simple vocal chanting of Om will not necessarily create this “easy” connection. It is easy when the vocalization of Om is accompanied by a deep feeling of the rest of the body (especially the spine) vibrating in resonance with the sound.
In chanting Om, pay attention to keeping the back of the throat wide open, allowing the overtones of sound to go very deep and wide, like in Tibetan Low-Voice chanting. The vibration then easily draws the mind deeply within.
The mind that goes deeply within when chanting Om will experience the sounds and their overtones as ethereal reverberations that have a way of holding body and mind in delicious resonance, as though electrified!
