The outer path we take is public knowledge, but the path with heart is an inner one. The two come together when who we are that is seen in the world coincides with who we deeply are. As we grow wiser, we become aware that the important forks in the road are usually not about choices that will show up on any public record; they are decisions and struggles to do with choosing love or fear; anger or forgiveness; pride or humility. They are soul-shaping choices.
Music is, and always will be, a method used by beings to bring about a unity between different vibrations, causing a harmonious note to the ear. In mystical fashion, one endeavors to achieve the same result with our intermingling vibrations of polarity. The thread, which binds in harmony, is the "music of the spheres." Its song plays continuously, but our ears cannot hear, unless our soul is tuned in.
