Everyone has their innate wisdom to heal. What Reiki and sound healing does is to help the individual to access this so that healing can take place.
Sound healing with quartz crystal singing bowls reaches deep into the cellular level. Every cell,every part of one's body has it's own resonant frequency. When this vibrates out of frequency, illness occurs. The sounds of the singing bowls helps to entrain the body to regain is healthy resonant frequency.
I was personally moved to obtain these bowls from my own healing experiences with them. They can be purchased from one of my teachers at:
