Second, I do not feel that setting of intention is needed in sound healing because once again the concept of mechanical vibration follows a different set up physics than electro-magnetic energy used in energy healing. Unlike the ability to change the production of electro-magnetic energy with just a thought, you cannot change the flow of mechanical vibration with thought alone. Electro-magnetic energy does not have the necessary mass to cause a soundwave to alter its course unless a volume of molecules within the travel path is heated appropriately to bend or refract the soundwave. However, this only implies that there is a change in direction flow, and it doesn’t mean there is any change to the environment where the work is being done in the human tissue of the client. So I do not think that “intention” or selective focus by the healer is needed in sound healing even with unweighted tuning forks in the air around the client.
