This is a PHENOMENAL video, which demonstrates toning and sound-vibration in action. To a certain extent, this explains what happens when a healing occurs.
In the video, some rice is randomly tossed on a metal sheet and just lies there in a chaotic mess. When the sound vibration begins, the rice starts to organise itself into patterns that resemble Mandalas, which are also in resonance with the sound frequancy, then and there. From chaos to order. This is somewhat similar to what happens with the healing process also. That is something to ponder on. To quote Fred Alan Wolfe, Ph.D., from the film ' WHAT THE BLEEP DO WE KNOW?'; "Ponder on that for a while!" :)...
obs! It might be a good idea to turn down the volume on your speakers first, as the sound gets quite sharp in this video and increases in volume and pitch.
