When one looks at the cosmos, the movements of the stars and planets, the laws of vibration and rhythm - all perfect and unchanging - it shows that the cosmic system is working by the law of music, the law of harmony. Whenever that harmony in the cosmic system is lacking in any way, then in proportion disasters come about in the world, and its influence is seen in many destructive forces which manifest in the world. If there is any principle upon which the whole of astrological law is based - and the science of magic and mysticism behind it - it is music.
