Sound and light affect our consciousness, for we (like them) are composed of vibrations. Music therefore is more than entertainment, and lighting, more than something to see by. Sound and light actually affect our consciousness, and help direct it toward spirituality, worldliness, or depravity. Be sensitive to the subtle effect of vibrations. Protect yourself from disruptive ones by listening to inspiring music, or by singing (even mentally) songs that are uplifting, and by surrounding yourself with calm, soothing, or brightly cheerful lights and colors.
