The sweetest harmony is made by the silent song of the Dao. The orchestra of the Dao plays with instruments that we could never comprehend or ever hope to hear play. Listened for it cannot be heard even by the best of ears. The music is cool and hot, loud and soft, fast and slow, incorporating the balance of yin and yang. Every note is pure. If we choose to dance to the music of the Dao, we will never be out of step in life. Even though we cannot hear it, we can be in rhythm with it.
