Music soothes the savage beast, but also enrages it. Each of your musical notes corresponds to an energy center within the body. Picture your subtle body like a keyboard with the energy centers as the vibrating strings attached to each key. As a note is played in the physical world, the relevant center vibrates in resonance. This is why certain songs strike you so blatantly. Yes, they activate your emotions, for each energy center is related to a specific emotion.
You have seen, perhaps, your Christmas lights that dance and light up in response to the notes of a song. This is what the body does. Can you see this in your mind? It is no wonder that you respond as you do to certain songs. You are being played by the vibrations of sound. Use music to your advantage. Soothe the soul or energize it as needed. Hold the image in your mind of the body as a vibrating, perfectly tuned instrument and let it sing in resonance with joy as you fill your life with joyful song.
