We are sound and we are profoundly affected by sound. Why? Because sound is energy and sound has the power to transform energy. (Think homeopathy- "Like cures like.") It works on all levels- physical, mental, emotional, spiritual. If you look a little more deeply into this video beyond the very cool effects, it actually demonstrates how and why sound can be such a powerful healing tool. We are composed mostly of water and free space, thus our bodies are excellent conductors of sound. Sound waves can penetrate all matter, but it flows easily through our bodies. Find the right frequencies and you can re-harmonize the body, the mind, the emotions- no different than tuning a musical instrument and in fact sometimes more quickly and easily than tuning a temperamental instrument! It's not complicated.
