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.
Any type of work can be meaningful. It is the spirit in which you do it that makes the difference.
Things just happen in the right way, at the right time. At least they do when you LET them, when you work WITH circumstances instead of saying, "This isn't supposed to be happening this way", and trying hard to make it happen some other way. If you're in tune with The Way Things Work, then they work the way they need to, no matter what you may think about it at the time. Later on, you can lookback and say, "Oh, now I understand. That had to happen so that THOSE could happen, and those had to happen in order for THIS to happen..." Then you realize that even if you'd tried to make it all turn out perfectly, you couldn't have done better, and if you'd REALLY tried, you would have made a mess of the whole thing.
