Some people say that the 528 cps is the frequency of love. Love is an intention coming from the heart. When a mother sings a lullaby to her baby they may not sing in the tune of anywhere near the frequency of the 528. It does not matter. The sound will carry their intention of love and healing. Therefore, the 528 forks, when used in this context can carry the vibration of love and healing the mother brings to it.
We do believe with strong intention and visualization, all healing is possible and the sound of the tuning forks, based on scientific research will create the environment in your body so that our biochemistry has a new chance to reorganize and create a new pattern for healing.
Some also claim 528 cps has effect on beauty!
