Consider for a moment that we are vibrational beings existing in a vibrational universe. Modern physics is discovering that on a quantum level we are all part of a harmonious interconnected web of wavelength and frequency, of sound and light, or music and colour. We are are a symphony of vibration co creating our reality with the energy that creates worlds. We each have our own beautiful music in us.
It is logical therefore if disharmony has arisen within us to treat vibration with vibration.
