Hinduism which is often regarded as the mother of all religions and is the oldest living religion in the world today has a concept called Nadabrahma which in its simplest terms means that the "World is Sound". It is believed that the whole universe, in its fundamental form, is made up of vibrating, pulsating energy. In fact at any given point of time all of us are vibrating. Whether we are standing, sitting, working or resting every part of our body is vibrating at different frequencies. One can almost imagine that each one of us is an individual musical chord and when we are in good health our chord is in harmony with the elements that surround us.
