An article written by D Cysarz & A. Bussing spoke of a report done which examined the effects of meditation on breathing oscillations and the modulations of heart rate.An electrocardiogram and a respiratory trace were recorded simultaneously as a series of tests were conducted. The bottom line was that "The high degree of cardiorespiratory synchronization during meditation in unexperienced meditators suggests that the physiological implications of meditation does not require prior experience in meditation."
Using Tibetan bowls in sessions works as in internal opiate and reduces pain as it initiates the relaxation response. This, combined with cardiorespiratory synchronization creates of the body a perfect container for healing. It has been my experience that people who are not accustomed to meditating (as well as those who are) are able to achieve a deep level of altered consciousness much faster during singing bowl sessions than in other forms of meditation.
