Ancient cultures developed medical systems based on energetic principles of the universe and somatic cellular body. The Sanskirt principle of Ayurveda describes the wheels of life or Chakras as originating from subtle energy known as Prana. This type of subtle energy can be modulated by electromagnetic field/visible light, to stimulate the brain/nervous system, cellular tissues, and bodily organs. Visible light is emitted in the form of photons that are absorbed through the skin and the active receptors in the eyes. Once absorbed, proteins or photopigments are activated at specific wavelengths to produce chemical reactions in the body. The reactions can produce various therapeutic biochemical benefits depending on their wavelength.
