I have found that the greatest degree of inner tranquility comes from the development of love and compassion. The more we care for the happiness of others, the greater is our own sense of well-being. Cultivating a close, warmhearted feeling for others automatically puts the mind at ease.
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.
